Over a year ago, this app was rejected from the iTunes store, but the Pulse Phone app has recently been accepted and returned better than ever.

Although it’s not the first app on the market to detect a user’s pulse, it's one that does not use the iPhone's mic to listen for sound like a stethoscope. The Pulse Phone App uses the tip of the user's index finger over the iPhone 4’s flash and camera lens to recognize the subtle color and brightness changes in blood as it is being pumped. The innovative usability of this app makes my heart beat that much faster.
