Cardiio Measures Your Heart Rate Using Your iPhone’s Camera [video]

Is it magic? We’re not sure, but we are sure that Cardiio can do something it shouldn’t just by looking at your face.

Is it magic? We’re not sure, but we are sure that Cardiio can do something it shouldn’t just by looking at your face.

Based on MIT technology, it measures when you’re face is reflecting more light and when it’s not, giving you a semi-accurate idea of your heart rate without ever having to strap a single sensor to your wrist, chest, or nether regions.

Cardiio is available for $5 in the app store
