So, I have an Apple Watch now. No, I didn’t feel a sudden need to check what time it is a few seconds faster (though ironically it does help because my new iPhone is a bit bulkier and a bit more awkward to pull out of the pocket).
I was primarily interested in getting something to help with general health and fitness monitoring. The Apple Watch wasn’t the only option here, as there are various other devices from Fitbit, Garmin, and other more fitness-oriented brands. After looking at various reviews and recommendations though, they all seemed about equivalent functionality-wise (there’s only so much you can do with a sensor package on your wrist, something to keep in mind when considering the accuracy of anything here), and I’m already tied into the Apple ecosystem, so what the heck, the Apple Watch it is.
Wearing It
It felt a bit weird to be wearing something on my wrist again, after decades of not having a watch, but it didn’t take long for that feeling to go away, and sleeping with it on hasn’t been a problem either. The crown is kind of awkward to turn though, but that might be partly due to my dumb fat fingers, and fortunately it’s not needed a lot since swiping up and down on the face usually works as well.
I probably would have liked the strap to be just a little longer, though. It’s fine on my wrist, but taking it off requires squeezing my hand an uncomfortable amount. Just a couple extra millimetres would probably have helped a lot. It’s not enough to bother taking it back and getting a longer strap though, for that small a difference.
So far the battery has been lasting about two days, in my usage. A bit disappointing compared to the other competing devices, many of which could go a full week, but it shouldn’t be too bad in practice. Most days I’ll have to take it off for the morning shower anyway, and that’s long enough to charge it to full.
Activity Tracking
One of the first things you notice is that it’ll start pestering you about doing certain activities, and standing in particular. There was a bit of configuration of this in the initial setup, but I kinda just rushed through and left most of it at the defaults. With that, it’ll track three metrics on a daily basis: calories burned, minutes exercised, and times standing up and moving around. I’m kind of skeptical about the first two; I have no idea how it’s tracking calories, and it seems pretty generous about what it considers exercise.
The standing tracking is useful though, as I’m prone to getting into long binges of just sitting at the computer. If my watch notices that I haven’t stood up in a while, it’ll ding and tap me on the wrist and display a reminder, and then I have to actually get up and walk around a bit to increment the counter towards the daily goal. Intrusive, but I do really need to get up and stretch more often. I just wish there was an option to ‘sleep’ the reminder, so it reminds me again in 5 minutes or so, in case the notification happens to come up in the middle of something that can’t be interrupted. It also sometimes seems to think that I’ve stood up when I actually haven’t, but maybe I’m just flailing my arms around too much while gaming…
Sleep
One of the features I’m really interested in is the sleep tracking, since lately it’s been feeling like I’m not getting the best sleep. You set the start and end times for when you usually sleep, wear the watch to bed, and in the morning you can review various stats. I’m not very consistent about exactly when I head to bed, or when I wake up on the weekends, but it seems to be able to handle variations in that well enough. You have to keep in mind that it’s not going to be 100% accurate (again, only so much you can do with just a sensor pack on your wrist), but it’s supposedly one of the most accurate of the current field of watches/wristbands.
I am a bit surprised with the data collected so far, though. It feels like my sleep lately hasn’t been so great, but most of these days the stats look pretty normal. There are nights where I wake up too often, but it doesn’t seem to last long at least? I’ll have to learn a bit more about how to interpret the results.
I’m also a bit skeptical of data like this:
where it looks like I fell asleep immediately, but I know that I didn’t, and just lay there for a long while before finally falling asleep. I guess I was staying still enough that it got interpreted as sleep? How much of that ‘deep sleep’ was just me lying there trying to doze off? Did that throw off the results somehow and that’s why there was no other ‘deep’ sleep recorded, or did I actually miss out on deep sleep that night? I’m not sure, and I guess it’ll take some more testing and seeing how I feel lines up with what the stats say. (Though it probably doesn’t help that I’ve been full of sugar from holiday snacking…)
It also claims to be able to notify me of sleep apnea events, which is something that I’m also concerned about. It tracks respiration rate and ‘breathing disturbances’, but the stats for that seem fine, and I haven’t gotten any warning alerts so far.
BLOOD BLOOD BLOOD
As you may recall from previous articles, I’m also a bit concerned about my heart, and it can track some stats related to that. Heart rate is a pretty simple one that anything can track nowadays, but it’s interesting to see the trend data for it. There are times where I thought my heart was beating rapidly, but upon actual measurement, it’s within perfectly normal range.
It also claims to be able to measure blood oxygenation level, but there are some caveats to it. Individual readings can vary quite a bit, so the general recommendation I’ve seen is to not pay much attention to those single readings, so don’t freak out if I do a sampling and it comes up at 93%, but to look at the overall trend line, which so far is staying in a pretty safe 93-100% range.
The star of the show is the ability to take ECG readings, though. It’s a very limited ECG since it’s only one-point, but it’s still supposed to be able to detect potential atrial fibrillation from that. It’s not continuous detection, unfortunately, which would apparently be impractical due to needing you to touch the crown and the battery drain it would cause, but it’s better than nothing. It’s kind of reassuring to feel a slight chest twinge, fire up the ECG app, and see that no, my ECG hasn’t turned into a big scribble.
Again, due to the limits of what it can measure and interpret, all of these should not be considered comprehensive proof that things are guaranteed to be fine and healthy, but it’s still nice to have a potential way of warning me. Consider it the SMART data for my body.
Apps
And of course, as an Apple Watch, there are numerous other apps available to do various other things. I haven’t looked into these too deeply yet, as I don’t really have an urgent need to play games or music or write texts or whatever from my wrist. Maybe later.
Overall, although I do have some skepticism about the data, it does seem like it will actually be useful. I need to get back into my walking routine, so we’ll see what kind of data I can collect from that as well. Worth the cost? Eh, hard to say, if cost is a major concern for someone, many of the other devices on the market will probably do just as well and cost a lot less.
