The cost of healthcare is not cheap in some parts of the world, and the What's My Heart Rate? app measures how healthy you really are. In western society the cost of healthcare could accumulate to half of the cost of living. There are a few options to combat this, including less quality, higher costs, innovation and/or self responsibility. The latter two can be combined with this DIY app.

DIY health is showing signs of real promise. The Nike+ allows users to monitor health progress, but more serious health apps are surfacing. What's My Heart Rate? is the first smartphone app that measures your heart rate without touching the phone. It uses the camera to detect micro color changes on your face, thus making it easier to monitor body functions.
