Decent

Once you figure out how to pair the HRM with the app the readout is generally fine. However, when I have the workout set to treadmill it doesnt log any miles. Maybe it doesnt work with the accelerometer in the phone? It would be nice if the voice feedback had more flexibility, like you could set it to give you average heart rate and/or current heart rate for the entire run and/or the current segment. Also, tonight it was telling me my avg heart was 170, but when I stopped it said my avg was 153. I dont know what thats about.
