Measure your heart rate using your Android device.

There's a free app I discovered on the Market called Instant Heart Rate that lets you measure your own heart rate (and it works!)

How to Use:

Download app, run it and place your finger on your phone’s camera lens, softly for around 10 seconds, with the LED Flash light ON, the app successfully measures your current heart rate.

How the app works:

By illuminating your finger with strong LED flash, the camera becomes capable of tracking color changes in the light that passes through your finger. With every heartbeat, your blood gets more oxygen rich, causing the color of your skin to change. The app measures these changes and calculates your heart rate based on them.
