Sorry to bump and old thread, but no point starting a new one, right?
Tomos, how have you got on with your monitor? Could you link to the one you have?
I want to use mine with Strava and JeFit. I find Endomondo would stop working too easily in the middle of a ride.
Also, if it matters, I'm using a Galaxy S3. It worries me many of the monitors specify which devices they work with, Bluetooth should be a universal standard, no?
