Instant Heart Rate
This clever, award winning app is based on the heart rate monitors used by hospitals and emergency rooms and gives you an accurate heart rate within 10 seconds. You place your finger over the camera lens and it uses the light from the flash to track colour changes in the light that passes through your finger. Sounds crazy but bizarrely it works!
Great for when you want a resting heart rate or are out on the trail and want to get a quick snapshot of where you are intensity wise. Just be careful if your phone has a case as it could be throwing off the beam from the flash. Also, certain phones work better than others.
The basic version is free from the Apple app store and the Android marketplace but there is a more advanced option with more features that you can upgrade to for a dollar.
