What for you will use "smart watch"? For real. There is not so much they can do and even less they can do properly

Not the OP, but my Apple Watch has changed my life. Being able to track, manage, and be challenged on my exercise habits has helped me lose 30 pounds in 7 months. Plus the convenience of knowing who’s calling without pulling my phone out, answer the call or text message directly from my Watch, check the temperature at a glance... And it’s pretty good at telling time, too.

  So just to be clear If someone wear 1-10-100 "smart devices" that someone do not loose weight You lost weight because you work hard, you eat smart and you change habits https://www.strongerbyscience.com/complete-guide-to-bar-speed-trackers/ https://www.strongerbyscience.com/complete-guide-to-bar-spee... About phone calls - I prefer do not answer at all. Better to recall or write message or mail About measurements - you really can't rely on any of wrist device sensors. They are not calibrated at all And even better. You body has so much more preciser sensors than any device. One device that can measure somewhat decent when you do exercises - chest strap monitor And I love tech a lot. But tech which can improve my or someones life

    This reminds me of the discussion where someone asserted that because were capable of taking our own pulse there’s no advantage to a device that tracks it all the time. I’m not going to throw a chest sensor on every time I leave for lunch just in case I decide to jog there. Or when I get up from my desk to run up and down the stairs. Nor is a chest sensor going to remind me to stand up every hour. Or allow me to set a reminder to take a bag out of my car when I get home. Or tell me what song is playing. You’re welcome to choose not to use a smart watch, but to claim they can’t improve someone’s life is willful ignorance of the facts. They’ve already literally saved lives.

      >to a device that tracks it all the time There is the problem with hand devices and quality of measurements they do Article describe it more properly If you have heart problems and you need some measurements there are a lot of medical _calibrated_ devices for that There are 0 devices for that which has only hand wearable part Also consider such cases when such devices can do a lot of harm https://www.theguardian.com/world/2018/jan/28/fitness-tracking-app-gives-away-location-of-secret-us-army-bases https://www.theguardian.com/world/2018/jan/28/fitness-tracki...

        You keep moving the goalposts. First you claimed they weren’t useful. Now they’re simply inaccurate (somewhat valid, but see below) and when used stupidly can be privacy problems. I can’t argue the latter, but that’s not just a smart watch problem. Regarding accuracy, though, the Apple Watch is very accurate for heart rate, which is important because it can alert the wearer to dangerous heart conditions. It’s also best-in-class accurate for calorie expenditure, which is fine for general day-to-day tracking and dietary planning. https://www.macrumors.com/2017/05/24/apple-watch-heart-rate-most-accurate-fitness-study/ https://www.macrumors.com/2017/05/24/apple-watch-heart-rate-...

        Not useful - because inaccurate on individual level Not useful - because algorithms for caloric expenditure are usable now only for group level experiments >that’s not just a smart watch problem True https://www.mdpi.com/2075-4426/7/2/3/htm#jpm-07-00003-f003 https://www.mdpi.com/2075-4426/7/2/3/htm#jpm-07-00003-f003 >Overall, heart rate error was within the acceptable error range for the majority of task/device combinations, but EE error exceeded the allowed threshold for all tasks and devices. And I repeat - for group level experiments such devices are good For individual, without calibration - not https://www.mdpi.com/2075-4426/7/2/3/htm#fig_body_display_jpm-07-00003-f002 https://www.mdpi.com/2075-4426/7/2/3/htm#fig_body_display_jp... You can see this on Fig2. That individual dots on image - that may be error on your device on your body And even more - I do not know what for you need your pulse measurements. Even accurate You do not need that number when you reach your peak velocity and do not need it when your sitting >It’s also best-in-class accurate for calorie expenditure, which is fine for general day-to-day tracking and dietary planning. I know even more accurate device for such purpose Scales And btw - scales can be mechanical so they can't send your data

Same things I used my Pebble for. Read and send canned responses to texts. See who's calling me. Read emails. Check bus/train schedule. Basically an extension of my phone. You can debate the "smart" label if you like, but the semantics don't really concern me.

  I'm more about "fitness and heath" aspect of such devices And probably just hate small displays in general
