Heartrate Monitor Live

Heart Rate Monitor Live measures your heart rate with your phone's built-in camera and shows you, based on your maximum heart frequency, in which training zone you are at the moment. The measurement process is very easy: just place your finger above the camera lens and after a few seconds your real heart rate is shown. Heart rates can be logged (e.g. for external analysis). Please note, that although HeartRateMonitor usually measures very accurate rates, it cannot be used as a replacement for a certified medical device!
