Cardio – Heartbeat Detection for iPhone
You might be familiar with the Heart Rate app which can detect your pulse by pressing your finger against the iPhone’s camera. Well Cardio is a new app that takes such voodoo to a whole new level – it can detect your heart beat just by being pointed at your face. It works by analysing the amount of light reflected off of your beautiful visage – you just hold your phone and look into the camera to see your BPM. It’s out now for $4.99.
