iPhone can now monitor your heart

Just when you thought the Iphone has nothing more to offer. A new app that I recently came across is called Cardiio,
Cardiio is an app that measures your heart rate when you look straight into the front camera of your iPhone.
How does this technology work? From the website “Every time your heart beats, more blood is pumped into your face. This slight increase in blood volume causes more light to be absorbed, and hence less light is reflected from your face. Using sophisticated software, your iPhone’s front camera can track these tiny changes in reflected light that are not visible to the human eye and calculate your heart beat!”
You  just  look directly at the front camera  of your iphone and you get your heart rate. Its that easy..

cost is $2.99
If you consider that many heart rate monitors cost over 60+ dollars, this is a great deal and can help you track your progress with your fitness goals..
