Heart Rate Monitor
Heart Rate Monitor is exactly what one would expect from a heart rate monitor app. It makes it easy check your heart rate by placing your finger on the rear camera lens or aiming the front facing camera at your face from about 15-20 cm away. I used my finger on the rear camera primarily during my tests. I found this mode to be easier to use and it seemed to provide more consistent test results. It was also less awkward then staring at my face in the gym while waiting for my pulse to be taken.
