Monthly Meanderings: August 2026

2026-09-01T00:00:00Z

Another month, another edition of “What’s Chris been up to?”. Fun fact: I very nearly published this post with a “[intro]” placeholder here instead of this paragraph, despite proofreading it multiple times. “Yep, that’s where the intro will go, all good”. Now instead we have this weirdly meta introduction.

Website updates and other projects

A few website updates this month, and one of them neatly addresses the “other projects” bit too. First, I’ve added a new fitness page which has some stats and information about my cycling and running. I’ve also added some fitness-related widgets to support that page and these monthly summaries, and a new music one you can see a bit further down.

I’ve also added what I think is quite a fun new feature: a post feed builder that lets you build RSS feeds containing only posts that are semantically similar (or dissimilar) to other posts. So if you want to only hear about my fitness journey you can pin a few of those posts, or if you want to exclude posts that talk about LLMs you can exclude a few of those. It’s basically super-charged fuzzy tags, but it means I don’t have to actually tag things.

I blogged about building a family of single-user services which is where most of my coding energy went this month. Those projects were almost entirely authored by LLMs, and I’m not hating the process. The models have got a lot better at coding, and I enjoyed getting to focus on the bigger picture aspects rather than getting bogged down in details. Rest assured, all the writing on my website is still 100% me. I am the load-bearing seam, here.

Entertainment

Back in March I said ‘I can’t do “what I listened to last month” stats until next month’, and then for the next four months completely forgot about it. Well, not any more! Now I come equipped with some stats about my monthly music habits:

	Album	Artist	Unique tracks played	Total tracks played
1	Fallen	Evanescence	8	40
2	Love, Drugs & Misery	Eva Under Fire	12	32
3	NEON VOID	Sumo Cyco	6	23
4	The Strange Case of…	Halestorm	11	21
5	Coming in Hot	DIAMANTE	9	20
6	Everest	Halestorm	7	20
7	Glory Days	Little Mix	5	20
8	From Zero	Linkin Park	9	19
9	KPop Demon Hunters (Soundtrack from the Netflix Film)	KPop Demon Hunters Cast	7	19
10	No Need to Argue	The Cranberries	6	19

I suspect I won’t show this every month, as it’s probably going to be quite same-y. I, shockingly, tend to play music that I like more than that which I don’t. I’ll usually either put on my “favourites” playlist, or my “daily mix” playlist which biases higher-rated tracks over lower ones. So effectively this just becomes a noisy view over how highly I’ve rated the tracks in an album. Maybe I can control for that, but then I’m not sure what it’d actually be showing… “Here are all the albums I played this month that I don’t usually play because I don’t like them as much as the other albums I’m not showing any more”? It’s a bit wordy. Back to the drawing board with that idea, I think.

I was away for a few weeks this month, including a few days at a small LAN event. Being at a computer gaming event meant that we, naturally, played some board games. Apparently I hit an h-index of 23 from these plays. That’s 23 games I’ve played at least 23 times each. I’ve been at 22 since December last year: obviously the higher the number goes, the harder it is to reach. I also go on and off games (and the whole hobby at times), which doesn’t help on that front. Anyway, here’s ~~Wonderwall~~ the plays for this month:

6 plays
3 plays

No films this month, but my World of Warcraft habit has picked back up with the launch of the new season. They’ve made Mistweaver Monk, my previous specialisation, a lot less fun to play, so I’m focusing on one of my many alts: a Restoration Shaman:

I don’t quite like it as much as Mistweaver in season 1, but it’s a lot nicer than Mistweaver in season 2. You can actually make health bars move when you press your healing buttons, rather than ignoring half of them because they’re not worth using.

Fitness

My running kick is still going. I’ve “officially” finished the couch-to-5k programme I was doing, and I actually hit 5k on the last day of the programme. I didn’t actually mean to do that: I was saving the 5k run for this week, but by the time I noticed I’d run “too far” it was close enough that I just kept going. I have an actual 5k race coming up this month, which is exciting. Once that’s over I’m planning to work my way up to 10k. I’ve added a few widgets to keep track of some stats:

As well as the running, I did a couple of long (for me) cycle rides, clocking in at around 40 km. It’s a fun loop, but both times I did it I started flagging towards the end. The second time I made sure to eat and drink plenty along the way, and my legs still raised objections about halfway round. My next goal is 50 km which would let me get to the next town over and back but the route has a lot more elevation to go with its increased length, so it’s probably going to be quite a bit more taxing. I’m not sure when I’ll attempt that, as the weather is starting to turn. I was previously bemused when people mentioned “cycling seasons” and switching to indoor trainers. Then I wanted to go out when it was raining, and suddenly I understood. Running in the rain: surprisingly pleasant; cycling in the rain: no thank you.

Hacker News In Uncompromised Detail

When I first read the title my gut reaction was “I know everything I need to know about Hacker News, right?”. The title is accurate though. There’s so much interesting stuff, presented really cleanly. It’s a good read.

Another dry sounding title, another fun article. It starts with a treatise on rating systems and ends with a lovely satirical list of rating ideas.

I like to think I’m relatively well versed in how to use Git. I can do an interactive rebase and everything! This tip from Ham was new to me, though, and is incredibly useful.

Novice Marathon Training Plan

Hal Higdon has a whole bunch of training plans. He literally wrote the book on marathon training. I’ll hopefully be following this plan next year, assuming I manage the 5k, 10k and half-marathon training! This would be the perfect plan for someone who’s run a half marathon a while ago, and is tempted to join me in my “marathon before I’m 40” goal…

Building a family of single-user services

2026-08-27T00:00:00Z

Last month I made and wrote about a personal service to track my workouts and record personal bests. Since then, things have escalated. I now have eight different services running in the same “family”:

Name	Purpose
Collegiate Room	Simple weather overview for my current location
German Mall	LLM broker for use by other services
Gloss White	Weight tracking
Olive Crosses	Central service hub
Pompei Band	Workout and personal best tracking
Speed Carp	Spaced repetition system
Tiger Island	Reading history and library tracking
Typical Horse	Location history and analytics

The names are all anagrams of something related to their function. Finding those anagrams brings me an unreasonable amount of joy. Unscrambling them is an exercise left to the reader. On top of those eight, I currently have four other service ideas sat in my todo list. It’s going to be a big family.

A postmortem on the previous hodge-podge

Most of this functionality isn’t new to me. When I started out playing around with LLMs, I created a “personal data aggregator” that just kept getting things bolted on. I said at the time:

My biggest just-for-me project is a web app that I started to help me aggregate film recommendations. It’s since morphed into a general personal data aggregation service: it deals with data from GitHub, Todoist, Letterboxd, TMDB, Healthkit, and others. It also lets me make re-orderable lists, store recipes, and more. Parts of this could definitely be open sourced, and I might carve them out at some point, but it’s mostly a glorious hodge-podge of things specific to me. Having all these services in one place lets me make quick and dirty automations, for example: when I create a Todoist note on my phone or watch, I often forget to set the due date, so it doesn’t show up in the “Today” view. It was literally a few lines of code to plumb things together so any inbox task without a due date gets set to today automatically.

In a twist that nobody could see coming, it turns out that a “glorious hodge-podge” is actually quite hard to maintain and very annoying to work with. It didn’t help that it had a fairly extensive Svelte frontend and I really am not a fan of JavaScript. I ended up using it less and less just because it wasn’t fun to use or work on, and I didn’t want to waste the limited LLM tokens on doing massive refactors or reworks.

I’ve got almost two decades of professional software development experience under my belt, so you’d think I would have learnt the lessons on how to write maintainable software. Hell, my CV even mentions that as something I’m particularly good at. So what went wrong?

There were a few factors. One of the obvious things to blame is that it was written mostly with LLMs. Most of that blame isn’t very honest, though. In the year or so since, LLMs have definitely got better at writing good code; but I was manually reviewing all the code at the time, and telling it quite carefully what to implement and how to do it. So the buck really stops with me.

I think it’s actually more because it was my first larger project using LLMs. It’s a bit like learning a new programming language. I don’t think the first sizable project I’ve written in any language has ever been any good. You can read and learn as much as you want, but you need to actually run into some problems headfirst to get a grip on how the language works. Or at least I do. LLM coding agents are basically the same deal.

What the LLMs actually did was mask several problems. The architecture wasn’t right for how the service developed. It started out as a single-purpose app and gradually got things bolted on, without any major changes. Everything ended up in horizontal slices: a massive database layer with every query used by every part of the app, a massive HTTP layer, and so on. Working on a single feature became a tap dance all over the source tree. This sort of friction is normally quite apparent when you’re writing code by hand, and at some point it hurts enough that you throw in the towel and do some refactoring. But the LLM will happily plod on without exposing that pain, so the project needed a more active kind of architecture management that it just didn’t get.

The other problem they covered up was how brittle and unmaintainable the JavaScript frontend was. I’m not even sure how I ended up with a Svelte frontend in hindsight. It’s my preferred framework, but I still only reach for it as a last resort when there’s no other way to avoid using one. It seems like there were lots of ways to avoid it here, but I seem to have… well… avoided them. Anyway, each feature got its own slew of Svelte components, without much thought to reusability, shared patterns, or anything sensible. Some of them were just thin wrappers around data supplied by Go, others had vast swathes of logic in them, with no real rhyme or reason as to which way that would fall. It’s the same issue as before: a human would look at it, say “WTF?” and suggest tidying it up; instead, the LLM just gets on with what you tell it to do.

There’s also a big non-LLM factor: one of the primary reasons all of this unrelated functionality got tossed into the same app was that I’d previously worked on a few projects with a microservice architecture and really didn’t like it. My conclusion was they only really worked in large environments where you can dedicate people or teams to working on all the boilerplate that happens from maintaining lots of interconnected projects. Dumping everything and the kitchen sink into one badly architected monolith was, perhaps, not the best rebound from that.

Pompei Band and beyond

When I wanted to implement ~~Strava at home~~ my PB tracking app, it seemed fairly natural to build it out as a new service, rather than bolt it on to the slowly decomposing hodge-podge that was giving off a funny smell. Then when I wanted a weather dashboard, why not do it in the same style as Pompei Band? The same serving architecture, the same page layout… I could even come up with a similar weird two-word name!

Then wouldn’t it be nice if the weather dashboard knew where I was, so it could show the local weather? I could just build that functionality in, but it’d also be a good opportunity to carve out the location history feature from my old service and make a new, shinier one. Then basically every time I even thought about going near the old service, I mentally sketched out a replacement service.

Olive Crosses showing links to the other services

At one point I had the thought that it’d be nice if the services could all link to one another, but I didn’t want to have to touch every service whenever I added a new one. So I made a “hub” service, which maintains the One True Catalogue, and provides a bit of JavaScript the others can all embed to add a navigation sidebar.

So after complaining about microservices and JavaScript, it sounds like I have landed on microservices (or at least miniservices) and JavaScript? Sort of yes, but sort of no. Each service is still its own thing and makes sense independent of the others. There are some cross-service dependencies, but they’re very simple and don’t have the same cognitive or boilerplate overhead as a login service that talks to an authentication service that queries a user manager and so on. And as for the JavaScript, it’s almost exclusively used for progressive enhancement and a few limited client-side visual things like maps and graphs. All of the logic lives in Go, which is a lot easier to maintain and test, and all of the pages are simple Go templates.

Having these services built in a way that I actually like has motivated me to play around a lot more with new features:

My workout tracking app pulls photos from my private Immich server that were taken during workouts, and shows them alongside. Now I can see all my obligatory end-of-run selfies in one place.
The location history app can detect trips away from home, and get an LLM to automatically title them. My most recent, very exotic, trip has the title “A fortnight in Milton Keynes and Coventry”. Each trip gets its own little map, and in the future I want to pull in images like with workouts.
My weight tracking app now exports weigh-ins to Garmin, as it doesn’t fully integrate with Apple Health (it will export its own weights, but not import others, like the ones from my Withings scales). Stupid walled gardens, but thankfully I can fix it myself.
My book tracking app automatically cleans up the titles of books from the nonsense provided by Amazon to something more palatable. “Killing Eve: Long Shot: A twist on obsession, betrayal and revenge from Luke Jennings, author of the TV sensation Killing Eve” becomes “Long Shot (Killing Eve #5)”. It does this by passing the title to an LLM with a bunch of rules.
The hub generates me a snippet of Tailscale configuration that defines the minimal grants needed to allow the intra-service dependencies to work.

The LLM integrations were inspired by my friend Shane who recently demonstrated an inventory tracking app he’d made, which used Haiku to process images of boxes and describe the contents. I’ve dabbled with LLM integration before, and always disliked the process of fiddling with the prompts, and debugging when the LLM gave a nonsensical response. So I built German Mall, which makes it a lot easier. It lets me define a “workflow” consisting of a system prompt, initial message, and expected response format. I can browse past runs, tweak the prompt, rerun them to see the change, all without touching the services using them. Quick iteration loops are the best. German Mall also provides markdown documentation for each workflow, so integrating it downstream is simply a case of pointing a coding agent at the right documentation endpoint.

The “tidy book titles” workflow in German Mall

It’s not all fun and games: having a bunch of services all following the same pattern means you need to do cross-cutting maintenance on them now and then. But that’s surprisingly easy with LLMs. I put all the projects in a common folder, and I launch cross-cutting tasks from that folder. Usually I’ll make the change in one project, and then the cross-cutting task is simply “Look at commit XYZ in ./foo, make the same change to the other projects”.

I’ve also ended up with a shared library used by all the projects to cut down on some boilerplate. That’s normally something I’d resist, especially with personal projects, just because the extra overhead of working in a separate project, managing releases of it, and so on, is a bit annoying. But, again, LLMs can do almost all of that grunt work. They effectively reduce the “cost” of maintaining separate services to a negligible level, leaving me to focus on the more fun aspects like coming up with new names.

Monthly Meanderings: July 2026

2026-08-01T00:00:00Z

Another month, another roundup post. This month has been very… exercise-y. Which is, for the record, not normal for me. For the previous year my only source of exercise has basically been walking, but that’s not a great fitness activity for me. When my regular walks entered the 10-15km territory it got more and more annoying to find the time and/or an interesting route.

I also managed to injure my knee while walking through a particularly muddy field, and spent a few months going slightly stir crazy. Coming out of that I started running three times a week, bought a bicycle, and added in some strength exercises along with the ones the physio recommended. If you told me a few months ago that I’d be annoyed at not being able to exercise too much on rest days I’d think you were mad.

Website updates and other projects

Before we talk even more about exercise, let’s do the usual topics I cover in these posts. The only website update this month has been a post about… exercise. Maybe I have a problem. Anyway, in Tracking PBs without the dark patterns I talk about building a slimmed-down, single-player Strava to track my personal bests, without all the nonsense that annoys me.

Other than the PB tracker, I’ve not been working much on personal projects. I’ve not really had any other itches that need scratching, just the usual background noise of dependency updates and other project maintenance.

Entertainment

Behold, the section where I normally talk about the films, TV programmes, and board games that have kept me entertained this month: […]. Yep, not a single one.

I have played a few games, though. A friend and I finally got around to trying out Escape Simulator 2, and it’s just as good as the original. The rooms feel a bit more detailed, and there are a few cool interactions that probably wouldn’t be possible in the old version. There’s also a hard mode for all the rooms which we’ve not yet tried, but sounds like it’ll keep us amused for a bit longer.

I’ve also been playing a bit of World of Warcraft, but it’s now in the awkward stage where I’ve done most things I can reasonably do this season, and there’s not really any point in doing anything else. All the gear will become mostly irrelevant in a few weeks when season two releases, and we’ve hit the major milestone achievements for Mythic+. Feels a bit anticlimactic to get to a fairly good stage and then just… not play for a bit.

Fitness

Given how much exercise I’ve done, it probably deserves its own section in these monthly posts. I have the vague idea of aiming to run a marathon before I turn 40 (i.e., within around 15 months). That’s both scary and yet not completely impossible. I’m going to work up through the distances and see how it goes. A 5k at the start of September, 10k in November, half marathon around Easter next year, then a full marathon just before my birthday in October. That way even if it gets too tough or something goes wrong I’ll have accomplished something.

New hobbies mean new toys. My bike is nothing particularly special: a hybrid from Halfords that’s about one step up from entry-level. But it gets the job done, and has helped me remember how much I enjoy cycling. The infrastructure around here is pretty terrible, though. There are lots of little bits of multi-use paths and a few dedicated bike lanes, but they’re not joined up or signed well in the slightest. In most cases it’s easier to just stay on the road and deal with the traffic. It’s a bit sad that they’ve spent time and money to do something and it’s not very useful.

On the running side, I picked up a Garmin Forerunner 165 watch. I’ve been wearing an Apple Watch for a little over a year now, but using the touchscreen to navigate screens and start/stop activities while running is annoyingly fiddly. The digital crown keeps getting gummed up with sunscreen and requiring cleaning, too. The Forerunner has physical buttons, and is much better at showing the data I want to see in a clear format, and letting me set things up like target pace or distance on the watch itself, instead of via a phone app. Oh, and the battery seems like it’s going to last for a week rather than a day, which is a nice change of pace.

I’m going to need to make a nice widget to show off my monthly runs and bike rides, but for now here’s some artisanal stats:

I went out for 14 runs, totalling 48km, although a significant portion of that was walking for warmup, cooldown or recovery.
My longest actual run was a 20 minute straight run covering 2.5km.
My average running pace is 8min/km, which is a “conversational” pace for me right now.
I went for 9 cycle rides: 2 on rented mountain bikes, then the rest on my own bike. They covered 128km.
When cycling I made 8 coffee shop stops, which works out to exactly one every 16km on average.

Next month I’m hoping to ramp the running up to hit 5k by the very end. I’m mostly following the NHS Couch to 5k plan but I’m tweaking it a little bit as otherwise I’d finish on 3.75km at my current pace. I guess “Couch to 30 minutes of running” isn’t quite as catchy. I made a Couch to 5k page to track my progress and adjustments.

Blogging Can Just Be Stating The Obvious

I often look at my own posts and think, “There’s nothing novel, or important, or deep in here at all — is this even worth saying?”

I’ve written before about The Curse of Knowledge and Blogging, and this is a very similar take from Jim Nielsen, but it’s still super interesting to see a similar idea expressed in another way by another person.

I Built a Voice Opening Door to Moria (My Garage)

A YouTube video documenting a really cool project. What grabs me is the amount of disciplines he dabbles in: he’s part blacksmith, part carpenter, part electrician, part programmer, and so on. It’s one of the best examples of maker culture I’ve seen in ages.

There’s one bit in particular that sticks in my mind: he tried to find a rendering of the door online, and realised all the existing ones were gibberish or illegible, so he downloaded a font and worked out the exact inscription himself. It makes my inner perfectionist feel validated.

Linus Torvalds on AI in the Linux kernel

LLMs are very divisive, and there are a lot of unsettled moral and ethical issues. But at the end of the day they’re a tool that’s not going to go away any time soon. There are people on crusades to try and ban LLM tools in projects, boycott any projects that accept contributions, and so on. It’s a bit like militant veganism. I can understand where they’re coming from, but also please stop shouting at me. Anyway, this take from Linus seems pretty spot on to me.

Buttons

An interactive, graphical history of how buttons have been rendered in various operating systems and desktop environments over time. Maybe it’s just my age and nostalgia, but it really does feel like they peaked around the late 90s/early 2000s. I’m not quite sure why we went from elegant skeuomorphic buttons to ugly plain squares with weird accent colours when you click them.

Rotating sandwiches

For some reason I expected this to be static pictures of sandwiches which spun in a circle, but it’s actually recordings of sandwiches rotating on a turntable. It’s oddly mesmerising. I wonder why I’ve never seen a restaurant menu with gifs like that?

Tracking PBs without the dark patterns

2026-07-23T00:00:00Z

I’ve recently been bitten by some kind of strange exercise bug. I’ve gone from being mostly sedentary to struggling to not go out for a cheeky bike ride on a day that’s meant to be a rest day. Maybe this is what a midlife crisis feels like?

Anyway, one of the things I’ve enjoyed about this development is seeing my personal best efforts gradually go up. There’s something incredibly rewarding about doing a run, and then seeing a nice little gold medal because as part of that you ran your fastest 1km ever. Unfortunately the only software I’ve found that does that is Strava, and boy do I not get on with it.

The many shortcomings of Strava

Strava is basically the app for running and cycling. Everyone talks about it. It sounds like they like it. But I really, really don’t. It’s like someone went through a catalogue of user-hostile behaviours and said “we’ll take them all!”.

The problems started in the setup wizard: it touts a load of privacy features, but doesn’t offer any way to enable them. All your activities are public by default, and you have to spelunk around in the settings to turn that off. I wasn’t actually sure if I wanted my activities to be public or not, and ended up flip-flopping around a bit. There is a clunky workflow to bulk change past activities, but it’s arbitrarily time-gated so you can’t use it too often…

The bulk operations are extremely limited, too: you can set the activity visibility, and your heart rate visibility, and that’s it. Want to bulk delete things? You’re out of luck. Bulk rename? No chance. You either do them one-by-one or use some janky third-party script. I think I pressed around 300 little ‘delete’ links in the course of trying to get my activity history imported in a way I liked.

Those problems give a bit of a signal about Strava’s priorities, but I could live with them. Once I’ve stopped faffing with the initial import I’m not really going to want to change the privacy settings or bulk edit things. Alas, the problems didn’t end there.

Look at me! Look at me! GIVE ME ENGAGEMENT!

The most obvious one is that everything is an upsell. Vast swathes of the app are premium-only, and they don’t ever get out of your way: they stick around acting as adverts. We’re all used to freemium apps that try to hawk upgrades, but the sheer amount of screen real estate taken up by these is egregious. I started a premium trial, expecting things to get a lot better, and… they didn’t really. All the premium features are still branded as such, so now instead of “look at what you could have if you paid us” it’s “look at what you’re getting for paying us (don’t even think about cancelling)”. Subscribing also makes your avatar get a premium outline, and there’s no way to disable it. I really hate that. Now I’m an advert myself. I don’t want to be part of their weird dark patterns, thank you very much.

And while we’re talking about dark patterns: there’s so much engagement bait that I physically cringe at it. You get a notification for logging an activity with a vague call to action to check it out. You get a separate notification when you break or come close to one of your PBs, but it doesn’t tell you which; there’s plenty of space in the notification for it, but they want you to hit the app instead. It all just feels so slimy to me. I don’t know whether it doesn’t bother other people as much, or if they’re desensitised to it, or just don’t realise how pleasant things could actually be.

Making a replacement

I realised pretty early on that if I only want automatic PB tracking, I could just write something myself to do it. I already use Health Auto Export to exfiltrate data from Apple Health, including workouts. I can just make a service that receives that data, crunches some numbers, and activates the dopamine receivers in my brain when I set a new record. But I didn’t really want to bother doing that if I could avoid it. I tried a whole slew of different apps and none of them did the thing, at least not without a subscription. And Strava had soured me on fitness subscriptions. I finally resigned myself to making something.

And by “myself” I mean “an LLM”. This is one of the first projects where I’ve not written a single line of code, and I’ve barely even reviewed anything produced by the LLM. I gave it an overall architecture and some sample data, and had it write a plan. I critiqued the plan, had it broken down into a few different phases, and then had it work through them. I occasionally stopped it when I saw it doing something stupid, and gave it a couple of technical steers, but my feedback has mostly been functional. I’m probably not going to be releasing it publicly any time soon for that reason — I don’t want to publish it under my name when I’ve not even looked at the code. I also wouldn’t be comfortable making software this way if other people were going to rely on it, but for non-critical, personal-use-only software I’m happy with the approach.

Anyway, I called it “Pompei Band”. Project names are hard. One of my common techniques is to put a term into an anagram finder; in this case “PB dopamine” anagrams to “Pompei Band”, and it even abbreviates to PB. Weird, but I like it. This is how it shows recent activities on the homepage:

Dashboard entry for a recent run in PB

You can click through to see the standard activity details most tracking apps show: a map, heart rate, pace, gradient, and heart rate zones. You can also click on each effort to see a history of them, which gives a nice overview of progress:

1 mile run PB history

It pretty much does exactly what I want, and has none of the annoying behaviours that Strava leans into. When I first drafted this post I wrote “there’s a few more bits I’d like to add at some point, but I can happily prompt them into existence when I want them”, but in the time I spent procrastinating before taking screenshots I ended up implementing them all. My favourite is this little history widget I added to the homepage, shown here next to Strava’s:

Recent activity calendar in Pompei Band and in Strava

The Strava one just confuses me. I’m not sure what the scale of the circles means. I’m guessing it’s time, which in effect means it just highlights my bike rides which are longer than runs. The colours for the line charts don’t work for me, and I’m not sure what three zig-zag lines are meant to represent. Pompei Band’s version uses distinct, obvious colours for different activities, and scales the brightness independently for each type of activity based on length (so long cycle rides don’t affect the short runs). I also flipped the axes so it looks more like a GitHub activity timeline, because that’s how my brain works. Nothing groundbreaking, but also none of the paper-cuts the Strava version inflicted on me.

Software doesn’t have to be awful

This blog post has been rattling around in my head for a few days. I didn’t want it to just be a litany about Strava being bad, and I didn’t want to sound like an LLM hype piece, which made it tricky to figure out what I was actually trying to say. I think the core of it is: software doesn’t have to be awful.

Everyone’s heard of enshittification, and it’s so prevalent that it’s easy to accept it as a fact of life. That’s just how late-stage capitalism works, right? But we can just make better software. And as LLMs slowly become more and more capable, that “we” grows to a broader and broader group. It’s easy to be negative about that: we’re going to drown in vibe-coded products, much like we’re already drowning in written LLM slop. On the other hand, a future where you can just say “make me single-player Strava without all the dark patterns” and get something that works just how you want it is pretty exciting.

The one thing I can’t decide: if everyone can whip up their own individual software, will the existing platforms actually improve? If Strava didn’t have all the dark patterns and engagement bait I would have just have paid for it. Will they realise that? Or will they double down even harder, try to lock you into their platform, and build moats around user data? Now I’ve said it, it seems pretty obvious they’ll try to do that. But I hope they won’t.

10 Weeks with an Apple Watch 10

2025-09-09T00:00:00Z

My watch. Yes, I am available for wrist modelling opportunities.

Around ten weeks ago¹ I picked up an Apple Watch 10, and have been wearing it almost constantly since. It’s not my first Apple Watch — I had a Series 5 for a bit back in 2020 — but it’s the first time I’ve actually stuck with it. Ten weeks seems like an apt time to reflect on it.

Firstly, why did I even bother? Well, for a couple of years I’d been wearing a Xiaomi Smart Band 7, mainly to monitor my sleep stats and set alarms that won’t wake up everyone else nearby. Its battery life was fantastic — with notifications and other things turned off, I got about a month of use between charges — but actually using it felt like trying to order food via the medium of interpretive dance.

My biggest gripe was the screen lock. If I didn’t have the screen locked then I’d periodically trigger it during the night when I moved around and it came in contact with my chest or leg. With the lock enabled you had to deliberately swipe up from bottom to top to enable interaction, but it didn’t work reliably. When I wanted to adjust an alarm, I’d be stood swiping repeatedly trying to get it to respond. When you finally get it unlocked, the whole interface is just fiddly.

The other issue was the data quality. There were some nights when I’d been woken up, sometimes even getting up and moving around, and it just didn’t show it in the data. If it can’t even get whether I’m asleep right, can I trust anything else it says?

I spent a while researching the best devices for sleep tracking. The Oura ring came highly recommended, but it was expensive and required a subscription to do anything useful. No thanks! The Apple Watch was consistently rated pretty well, and I reasoned I could pick up a refurbished older unit. I’ve been using an iPhone as my daily driver for a while, so it’d fit right into my begrudged walled garden.

The Series 10 has a significant advantage, though: it charges much quicker than all the previous generations. On a 30-minute charge, the Series 10 can go from 0 to 60%; the 9 can only make it to 40%, and my old 5 a measly 30%. Shorter charge times means I’m far less likely to leave it on charge and wander off without it. In some ways the daily charging is more convenient than monthly: the wireless charger sits on my desk, and I plop the watch on it for a little while in the evening; I don’t need to dig out the weird pogo-pin connector that has vanished sometime in the last four weeks, then carefully arrange it so it stays attached.

How a watch maybe saved my life

One of the big features of the Apple Watch, like many other wearable devices, is health and fitness tracking. I didn’t think much about this, beyond the sleep data I wanted, at first. I’ve never had a particularly good relationship with exercise², but I do like some good statistics. I started going for walks more often to get more data and see the graphs of VO2 max and HR recovery gradually inch up. That wasn’t the most profound effect on my health, though…

The recent versions of the Apple Watch have a feature that monitors for sleep apnea, a disorder where you don’t breathe properly during your sleep. I knew I wasn’t sleeping great — that’s why I was paying attention to sleep tracking data — but was still a bit surprised to get a notification from Apple Health after wearing the watch for 30 days. It gives you a graph to print and take to your doctor. So I diligently booked an appointment and a few weeks later went to see my GP.

The appointment went about as you’d expect: talking about referral to a sleep centre for a study, and so on. Towards the end, the doctor took my blood pressure (sleep apnea can be caused by, and can cause high blood pressure, in a lovely little vicious cycle). I don’t think either of us expected anything; it was just one of those standard checks for a related problem. After taking the reading, the doctor looked at me and said, “I can’t let you leave with a BP like this”. Yikes!

Blood pressure readings are split into stages: normal is under 120 mmHg³ over 80 mmHg⁴, stage 1 is up to 140/90, stage 2 is up to 180/120, and above is simply called “crisis”. Guess where I was? Also, fun fact: depending on how exactly you count and attribute things, hypertension comes out as the single largest cause of death in humans. It doesn’t kill you outright, but contributes to strokes, coronary artery disease, heart failure, and lots of other lovely things you don’t want on your CV.

After doing a few more readings, it settled down to just under the “crisis” stage and into the “holy crap, start treatment immediately” stage instead. I won’t labour on much more about this, but things are definitely moving in the right direction now⁵.

While the Apple Watch didn’t literally save my life, it triggered the chain of events that led to this diagnosis and treatment. Who knows what would have happened had it remained undetected? Probably nothing good. Also, go check your blood pressure! It’s simple to do and simple to treat if there is an issue, but so many people are walking around with hypertension and not even realising.

Building gates in the walled garden

Even though the watch is arguably a life-saver, not everything is rosy. It’s an Apple product, so you’re firmly locked in a walled garden, jealously guarded by people wearing black turtlenecks. Fortunately, there are a few ways to make it less painful.

All the health and fitness data is stored in Apple Health. You can export data as a big messy file, but it’s a very manual process to do so and the data format is gnarly. Luckily, there’s an app for that! Health Auto Export can, well, automatically export health data. It does what it says on the tin. It can send the data to Home Assistant, over MQTT, or dump it in some cloud file services, but I just have it post it all to a REST endpoint on a service I wrote. Then I dump it all in a database and can do whatever I want with it!⁶

Another tool that’s more useful on the watch itself is Apple Shortcuts. This is their no-code “if-this-then-that”-type thing. You can make automations or shortcuts that run a number of tasks. I have a whole slew of them I access via a complication⁷ on my watch face: one which prompts for input and adds an item to my to-do list (swiping to write letters is surprisingly not horrible), one which lets me select from a bunch of pre-written ones (“charge kindle”, “take laundry out in 1 hour”, type things), one to log my weight into Apple Health, one which can open and close the blinds in my room, and so on. It’s a surprisingly robust and easy-to-use system and offers just enough freedom that I’m not constantly grating on the edge of the walled garden.

Shortcuts being able to initiate arbitrary web requests is the real killer feature for me. Anything I can’t do on the watch itself, I can just farm off to a web server and connect it up with a shortcut. No need to learn Swift or pay Apple for the privilege of being a developer! For a lot of things, like controlling the blinds or adding to-do items, I already had a HTTP endpoint available and exposed over Tailscale⁸. Adding it to the watch was just a case of entering the right things in the Shortcuts app.

Daily nitty-gritty

There are lots of other little bits and pieces that come up when using the watch daily. I don’t think I can bundle them up into a pleasing narrative arc, so instead please enjoy some disjointed paragraphs of observations.

The Apple Watch has a lot of nagging abilities. It can notify you about your fitness “rings”, prompt you to stand up every hour, count how many seconds you wash your hands for, etc. I think I’d dislike these just on general principle, but the way it does them is so condescending it’s painful. I think there’s probably a cultural divide issue here, but there is no way in British English to say “Great job! You washed your hands for 30 seconds!” without it sounding like you’re being amazingly sarcastic or like you’re talking to a young child. So I turned all of that nonsense off. It’s meant to be a tool not a wannabe life coach.

You can access Maps directly on the watch and even do navigation. It works really well. The navigation mode has some nice haptic feedback: it does a short pulse as you’re approaching a turn, and then a long pulse at the actual turn. I like it a lot more than having to dig out my phone or have the directions read out. You get one pulse, glance down and see where you need to go, then it reminds you a little later when it’s time to do it. It’s a delightful user experience.

Watchfaces aren’t quite so delightful. There’s a limited number of built-in ones, and some are “exclusive” to the Ultra Series, and you can’t use them on a peasant watch like a Series 10. Annoyingly, there’s not one that does exactly what I want: a plain analogue clock with an inset date and four complication slots around the outside. Instead, I have to use one of the slots to show the date. There are third-party watchfaces, but they have issues. Firstly, there’s no actual API for making watchfaces⁹, so what they do is bodge it horribly by using a photo background that has fake widgets on it. On top of that they’re almost universally subscription-based. Again, no thanks¹⁰.

The issue I had with the Smart Band triggering when I was sleeping is solved trivially on an Apple Watch, by virtue of it having a physical button in the crown. When you put it in sleep mode, you have to double-press the crown to unlock it before it’ll do anything else. It hasn’t misfired once while I’ve been using it.

Sleep data; spot when I swapped devices!

Finally, a special mention for the gesture controls. If you raise the watch it reliably wakes up (switching from a low refresh rate, dimmed screen to an active, brighter one); you can then double-tap your index finger and thumb together and it will scroll down or page through whatever you’re looking at. The killer feature for this is navigating recipes: you can advance to the next step in a recipe while your hands are covered in flour. It’s also handy for reading notifications: when one pops up, you can double-tap to expand it, then, when it gets to the bottom, it’ll outline the default button (often “Dismiss”) and you can double-tap again to click it.

The verdict

I normally don’t like writing an actual labelled conclusion, but it feels like one is needed here! Overall, I’m happy with the watch. The daily charging doesn’t bother me, the data gathered seems reliable, the health monitoring has obviously paid dividends already, and the walled garden isn’t too chafing. It’s a straight upgrade over my old Smart Band, and I think it was worth the cost.

The original reason for getting the watch was better sleep tracking, though, so how well did it do? I’m much happier with the data: it seems to more accurately represent when I was awake in the night, and overall the sleep phases just seem to make more sense. You can see in the graph that the old data switched frequently between phases, and they didn’t quite line up for some reason; towards the right when the Apple Watch is supplying the data instead there’s a much more consistent pattern of sleep phases that repeat over the course of the night.

I’m not going to advocate that you go out and buy one, though. I know my requirements and usage aren’t typical, and I’ve also not got experience with any recent Android Wear alternatives or the new version of the Pebble watch that’s coming soon. You should definitely get your blood pressure checked, though!

OK, it’s more like 14 now, it’s taken a while for this post to make its way from my brain into text. ↩︎
Exercise for the sake of exercising just seems so overwhelmingly tedious and boring to me. And other types of exercise generally require social interaction, coordinating with people, and so on. ↩︎
Who decided to use “millimetres of mercury displaced” as a unit? You can’t just put random chemical symbols in units! That’s not how this works! ↩︎
Blood pressure readings have two parts: systolic (the pressure when the heart is beating) and diastolic (the pressure between those beats). They’re generally presented with the systolic reading on top and the diastolic reading below, and read as “X over Y”. Now you know what some of the random numbers they shout in medical shows mean! Yay learning! ↩︎
No thanks to how much salt is in everything. I’m pretty sure I’ve had at least twice the recommended daily amount of salt in a single serving before. Don’t even get me started on the things that are “low salt” but are still full of sodium from other sources. I don’t have a problem with ionic compounds, I have a problem with sodium! ↩︎
This mainly looks like drawing graphs that are slightly different to the graphs in the Apple Health graphs, for reasons I’m not sure I can explain. Making graphs is fun, OK? ↩︎
Complications are basically just home screen widgets, but with a fancy name because they’re on a watch. ↩︎
Tailscale actually causes me some problems here: everything works fine when the watch is connected to my phone, as the phone handles the Tailscale part, but if I’m not carrying my phone the watch will try to connect over WiFi directly and doesn’t understand anything about Tailscale. It happens infrequently enough that I’ll just live with it; it’s not much worse than having no signal on a phone. ↩︎
Yay walled gardens… ↩︎
I don’t object to subscribing to things in general, but it has to be something that’s worth the ongoing cost and offers something in return for the subscription. A watchface doesn’t need enough ongoing maintenance to justify subscribing to it, it’s just a cash grab. ↩︎
