BT Mobile app - When are we getting a good one!

Hello,

I'm a long time BT user and BIG fan, however the distinct lack of support for mobile devices is frustrating. I know you have a basic app for Android and iPhone however there are so many cool apps for tracking workouts. It would be great to see BT come up with something in this space. It would be really great if you had somthing like the FITBIT that could track a bunch of other fitness factors such as sleep etc etc. 

Cheers, Paul
