I find the current generation of smartwatches a complete waste of money. Other than the signaling factor of the iwatch, i found it annoying and utterly useless. Between the wrist-shock vibration (hey my phone is already vibrating in my pocket) to the annoying "breathe" app, this is by far the worst apple product i ve used. But it's not their fault, it's a problem with the genre. Between the daily-recharge hassle, the inability to have an always-on screen, the lack of a killer app and its relative fragility , watches like these are doomed. I much prefer the $30 xiaomi mi band as a sort-of tracker.
(this is just my opinion)
