Instant Heart Rate: A Cool Way to Track Your Ticker
Every now and then I'm surprised and delighted by the utter ingenuity I stumble upon in the iTunes App Store. I really like it when someone utilizes common technology for a unintended purpose -- in this case, using the camera on your iPhone to track the beat of your heart. Crazy, I know, but Instant Heart Rate - Heart Rate Monitor by Azumio does it in just a few seconds.
