Certain innovative apps manage to impress you the first time you use them and make you wonder exactly what goes on behind the scenes. Instant Heart Rate is such an application. By placing your finger on your phone’s camera lens for a few seconds, it manages to measure your current heart rate.

When your heart beats, your blood gets more oxygen rich and that causes the color of your skin to change slightly. The app measures these changes and calculates your heart rate based on them. Pretty cool if you ask me.
