Cardiio

Cardiio Magic

Yesterday, LT was showing me Cardiio - an iOS app that claims to "turn your phone into a biosensor." Being the eternal skeptic I assumed the app was a well designed piece of BS. I mean, read this!
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!
My knee jerk is to doubt it but based that paragraph is based on actual science, not marketing mumbo jumbo.

In summation, Cardiio is unbelievable magic.
