It is giving me wrong HR figures while exercising.
It seems to work better when you don't move at all.
A bit disappointed since this is a fit-watch and not a smart-watch.
I saw today the HR tests of Apple Watch from the quantified scientist in youtube and I was impressed.
And Apple Watch is purely a Smart watch with some fit capabilities here and there.
Fitbit should have been the leader here. It's their field to have better fit capabilities.
