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...
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.
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.
>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
