Here is a simple way to use you iPhone as a heart rate monitor with the camera and led flash. A simple app called Runtastic Heart Rate Monitor & Pulse Tracker. All you have to do is launch the app, set up your account and then place your finger over the camera and LED flash. The app takes care of the rest and the results are just as good as the dedicated heart rate monitors on other smartphones.
