Saw an app that does this on the android platform so thought I ‘d give it a go on iPhone.


It measures your heart rate by looking at the changes in skin colour as the blood flows in. It’s only available on the iPhone 4 as it needs the flash in torch mode to work.

You can get it here - it’s free! http://itunes.apple.com/us/app/heart-rate-free/id401450171?mt=8



I’ll do a blog post soon on how it works. It’s surprisingly simple.

Why not subscribe to my mailing list - I'll send out regular emails with new content (don't worry I won't spam you!)
