Sorry but no automatic sleep detection

Auto sleep does not work
App is too basic - should provide more details / info
Should be able to give a resting hearth rate on a daily basis not only at night time

Should be able to add manual training as hearth rate during exercise is way off . Automatic training hearth rate is useless showing 150-180 Bpm when the real HR is low 130

Should offer a lot more watch face - too basic

Should be bake to add daily notes .

Etcetcetc

Band is ok but a bit too bulky - looks like a GPS tracking device for convicted people :)
