The app is so much better than the iphone one. The good parts are :-
* Asks permission to turn on BlueTooth when you start the app * Does now show maps etc. * Liaises with RunKeeper by sending it's data after an activity - more later. * It seems more accurate most of the time.
The bad parts are :-
* The app allows you to select metric units, but asks for your weight in lbs always * Switching away from the app to make a phone call, causes it to stop recording your current session * It recorded my heartbeat at 249, whilst walking up a hill. Surely I should be at the docs by now. * Whilst cycling on one trip it dropped out for a minute or two
So whilst it is an improvement on the iPhone issues it is way from perfect.
