Measure your pulse on your Android or iPhone with Instant Heart Rate

Have you ever exercised and needed to know if you’re in the target heart rate zone?  Well here’s an easy and free way to do it.  Try Instant Heart Rate for android or iPhone.

All you have to do is place your index finger under the lens of the phone’s camera and it will measure your pulse.  It works best on phones that have a led flash.  I tested it both on the iPhone 4 and the Droid X and it seemed accurate.


You can upgrade to the paid version for $.99 if you want to keep a history and activity log.  This could be useful if you are tracking the progress of an exercise program like P90X and want to see if you are reaching an overall lower resting heart rate.
