Limited and buggy
First right off the bat, Im not a fan of this app because it assumes that youre sleeping when you press on start. I would have liked for it to start counting actual sleep time the moment you started to not move as much (actually sleep).
I have only tried this app 2 times since the big update and both times when I tried to sync the data to my iPhone (I took the watch off airplane mode before even ending tracking) the data wouldnt sync to my iPhone and it would disappear from my watch.
Essentially youre better of just using an iPhone app to track your sleeping since this isnt working as claimed.
