It really needs to vibrate on the start of the run/walk/exercise. On the workout app, It does a 3 second count down and should do haptic triple pulse when it starts. Seems like common sense. I really want to know who beta tests this stuff over there. Real runners would have a field day with how bad it is. Can't edit the workout upon completion, heart rate blows. Not enough info on the screen..... So many problems.
