what workout app do you use replay? I'm a hamster bike for my excercise, so I've been using Endomondo. They are the only app I've found that actually thinks hamster bikes are exercise, and will track it.
Biggest downside to the gear fit is they don't let 3rd party apps access the heart rate monitor for some reason. If they had that, and a few small things, it's a great cheap watch. Or more of a remote for your phone.
