I've loved the idea of a computer on my wrist since I was a kid but now they're available, I find myself unable to think of an actual useful application for them apart from telling the time - what do you smart watch people actually do with them? Are they mainly toys or do they enrich your life in some practical way?

[perrygeo]

Biometrics, heart rate and sleep tracking are huge, like 95% of the reason I own a smart watch. It's a sensor, not a UI. Everything else can be done better on a phone.

I turn off notifications (because if I get a message on my watch, what am I going to do with it? watch is basically read-only)

One use that comes up a lot: setting a timer. Being able to ad hoc set timers with your voice is huge - without it, my coffee would get cold, my laundry would stay wet, and my kid would be late because dad got distracted by a HN comment.

1. Notifications. Most useful in noisy environments such as grocery stores, airports, shop floors, or any place you may be wearing hearing protection. Also great while working with your hands, like car work or cooking and directions while driving. It’s best to limit them to the apps that matter, and only when you need them.

2. Biometrics.

However, after this watch finally dies, I don’t think I will be going back. Big reason is smart watches are not stylish at all. For men watches are our only fashion accessory that we can freely wear in all occasions. No matter what band or watch face you use you are stuck with a black square attached to your wrist. Also smart watch battery life is a bit of a bummer, it’s hard to beat self winding or solar powered watches that you never think about changing as long as you wear them.

[danparsonson]

Yeah the battery life is off-putting for me - watches I had as a kid would last for years on a single battery so I think I have that expectation stuck in my mind. I do like the biometrics angle - something that tracked my health condition and alerted me to any problems would be interesting, but it would have to be fully under my control; I'm not keen on my health data disappearing into who knows what databae.

Garmin smart watches can last weeks on a charge

There are reportedly solar smart watches. I do wish my dumb watch was a tad smarter in that it doesn't get automatic time updates, but that's not impossible even without a phone. I haven't found one that's waterproof, solar, wireless time, and the right price though.

It helps mine runs a bit fast so I'm early to things. If it ran slow I'd probably have replaced it years ago. As is, I'm going on 10 years with barely taking it off my wrist and never charging or replacing a battery, and I'm not the first owner.

[asciimov]

Citizen has an Atomic Timekeeping Eco-Drive series of watches that have a 200 meter water resistance. If you like complications see the Promaster Skyhawk A-T.

[Neywiny]

Sadly I got my current watch for free and it still works. And I don't really get dressed up for stuff. So while yes they certainly do have a series of nice looking watches, I can't justify the purchase at the moment.

[crabbone]

I run every day. Started doing it for multiple reasons, some of them being health. The watch tells me my pulse, speed, cadence, calories burned. I doubt the numbers are very accurate, but they are consistent, and, probably, not too far off outside of cases of obvious misreading. It also has a way of collecting some data about swimming (which I don't understand, like what is swolf? I know, I could look it up, but I'm a terrible swimmer, so I don't bother).

For people who like to leave their phone in random places around the house, the watch can help in locating it. You can also almost always turn off the alarm on your phone w/o getting out of bed (provided you sleep with your watch on and the phone's bluetooth didn't decide to randomly disconnect).

All this said, I think that smartphones, in general, provide very marginal utility. A little bit of convenience here and there but nothing groundbreaking. If phones had better GPS antennas and a framework to attach devices like pulseox or sphygmomanometer they'd be preferable to the watch because the display is bigger and the input is (slightly) more convenient.

[danparsonson]

Yeah fitness tracker is a good one; I'm the opposite with my phone though - I get a ton of utility out of mine, but not things that I think would be improved by shrinking them down onto my wrist.

[Silamoth]

I stopped wearing my Apple Watch because notifications were too distracting when trying to work (even with Work Focus, I want some notifications, but I don’t want my wrist buzzing and lighting up all the time). I don’t miss it. The only real use I ever got was GPS directions when riding a bike or electronic scooter. I guess I also tracked my runs with it. But I don’t use those often enough, and I can wear the watch for those situations if needed.

I do also love the idea, though. I think part of the limiting factor is that you can’t attach sensors or peripherals to it. Even with a hackable watch like in TFA, there’s only so much you could add without it getting bulky. And the screen is too small to do much with.

[neurobashing]

I switched from Apple Watch to a Garmin Fenix 7, for much longer battery life (advertised as ~14 days, in practice 10-12), durability (they're very tough), better biometrics, and stuff like built-in maps/GPS (I camp/hike/hunt/etc a lot). I just didn't use any watchOS features, and I use an MVNO that doesn't support sim cloning so cellular's a wash. In short even with reduced features I am considering just going back to an old analog Timex Explorer and using a dedicated GPS device, because even the more limited feature set of the Garmin seems like I'm barely using what it's capable of.

[rhubarbtree]

Don’t have one capable of it, but listening to music whilst running without a clumsy phone to hold/strap to my arm/put in a silly belt would be awesome.

[danparsonson]

Yeah, we used to have MP3 players for that - I still have my Sansa Clip+ in a box somewhere...

[arximboldi]

As a former user of the Sansa Clip, I recommended the Shanling M0 as a modern alternative (they sell a separate case for the clip if you want that). Great audio quality and features, format and Bluetooth codes support.

[danparsonson]

Thanks, I'll take a look!

[Revanche1367]

Same here, loved the idea since I was a kid and I spend a lot more money on gadgets than I probably should but somehow managed to avoid getting a smartwatch because it doesn’t do anything a smartphone does better. I just wear a simple casio solar powered watch I got for about $100 which I never have to charge. I still like the idea of something programmable though, but this watch in OP is a bit too DIY for my tastes.

[crabbone]

Smart watches, in general, have a better GPS antenna. I tried running using just my phone's GPS and it's all over the place, completely unusable for that task (it showed me crossing walls, canals, running in circles where I went in a straight line etc.)

Also, a lot of smart watches come with a pulseox, so, you can look up your pulse any time you like :D Not super useful unless you are working out, but there's that.

[cityhall]

They're great for doing phone stuff without pulling your phone out of your pocket and unlocking it. I can check if a notification is important, get GPS directions, snooze alarms, get OTP/2FA codes, or check the weather. None of it it is critical but it's collectively a quality of life improvement.

[saltcod]

Just two things for me: telling time, same as yourself, and notifying me that my watch has a text message I might want to attend to. If I could replace the notification feature somehow I’d do that.

I used to use it for running but it performs that job very poorly compared to my $200 Garmin.

[culopatin]

Lately the only useful thing I get out of it is Auto Unlock my phone when I’m wearing a helmet and gloves.

[narag]

Some applications that we use in smartphones are very useful, like the alarm clock. I have begrudgingly adapted to their quirks and privacy implications. I'd rather program my own versions, same for smartwatches.

[danparsonson]

Alarms I can understand, but that's been a feature of standard watches almost since they were invented I think. I'm looking for something that requires a programmable device to be meaningful and so far the ideas are fairly thin on the ground :-) I get the techy appeal though, and agree wholeheartedly about the value of having total control over a device if possible.

[narag]

In case you're still reading... standard watches alarms are useless to me. Even regular alarm clocks were not very effective for my kinda morning sleepwalking.

Smartwatches are a godsend: I can set multiple alarms with chosen intervals, volume and ringtones, that never stop and place the phone easily at the right distance.

I could even improve on that and the same could be said of most phone apps. Recording and positioning are the most interesting features if they can be decoupled from big brother's eyes.
