Ok this could very well be the coolest, and most important for your health, iPhone app I have seen in a long time. It’s called Cardiio and it measures your heart rate just by looking directly at the iPhone camera. I learned about this app this morning on the Fast Company design blog.
The app works by looking at the blood flow in your face – and apparently it comes pretty close to perfect accuracy!
There are plenty of heart rate monitors out there – what makes Cardiio different is that you don’t need any attachment – you just look directly at the camera on the iPhone and it provides you with your current heart rate. Since most of us workout with our mobile devices, this seems like a great way to be able to tell your heart rate anytime and anywhere without the need to carry a heart rate gadget with you.
The app also tells you life expectancy, fitness level over time and has some cool graphs.
The Cardiio app is $4.99 and appears to only be available for the iPhone 4S.
