By installing this app, you can measure your heart rate through your phone's camera lens by just placing your index finger on it. Make sure the flash and camera lens are both shielded so the app will work properly.  The heart rate monitor will begin tracking your heart rate when you press the button in the center of the app. All results can also be saved on your phone to check over and over and to compare each result.

Just a heads up, the app has not received approval from any medical organizations, and it is not a medical app.
