Great App

Extremely useful"I use this app with my Scoche Rhythm heart rate monitor for boxing and kickboxing. It works flawlessly and gives not only very accurate and easy to use data but provides many different options so you can customize your training data. I especially like that it validates my calories burned based on calculation from my heart rate. This app is the very best...simple, intuitive, and extremely useful.
