PLEASE UPDATE FOR iOS 9

As a certified personal trainer, this heart rate monitor and app combo is unmatched in accuracy. If you are having issues with calibration, make sure you are doing the assessment at least once a month, and make sure you dont put the sensors on your body dry. Get some water, moisten the sensors up so they can get a good reading. I would have given this app 5 stars but its currently useless because it has not been updated yet. PLEASE UPDATE FOR iOS 9!!!
