10 Weeks with an Apple Watch 10
Published on

Around ten weeks ago[1] 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 exercise[2], 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 mmHg[3] over 80 mmHg[4], 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 now[5].
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 complication 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 Tailscale[7]. 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 watchfaces[8], 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 thanks[9].
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.

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!

Exercise for the sake of exercising just seems so overwhelmingly tedious and boring to me. And other types of exercise generally require social interaction, co-ordinating with people, and so on. ↩︎

Who decided to use “millimeters 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? ↩︎
-
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. ↩︎
Thanks for reading!

Fixing a loud PSU fan without dying
Three months after I built my new computer, it started annoying me. There would occasionally be a noise that sounded like a fan was catching on a cable, but there weren’t any loose cables to be a problem. Over the course of a few weeks, the sound got progressively worse to the extent that I didn’t want to use the computer without headphones on. I measured the sound at 63 dB, which is about the sound of someone talking. That may not sound terrible, but it’s a constant, nasty noise coming from something that sits about 40cm from my head.
