Great app

New Review 9/11/2016: App worked great every time for last 3 years until 9 months ago. I purchased new batteries for Runtasic heart and cadence/speed sensors, heart sensor works fine, speed/cadence sensor never resumed working, does not pair, turns green, shows paired, but doesnt show RPMs while riding or in results at end of ride. Purchased both Runtasic sensors for my wife at Christmas 2015, same mountain bike app, same problems, no cadence sensor readings. I wrote to Runtasic several times, only auto robotic replies with no solutions. Poor customer support. And, as other have mentioned, location services, create an option for on when using app. I guess Ill delete app and toss sensors in recycle bin, better products out there...

Old Review Ca 2013 was 5 stars:
Works great every time, calorie burn may be a bit too high than actual...
