iHeart is a device and iOS application using a fingertip optical sensor to record the arterial pulse for 30 seconds and display an objective health index: Internal Age. iHeart measures Aortic Stiffness, a scientifically accepted predictor of overall health. With positive lifestyle choices and regular testing, iHeart users can watch themselves getting internally younger, with improving health and longer lifespan. Each iHeart user's results are stored on their own personal dashboard where they have access to diet, fitness and lifestyle resources and the iHeart community. 

Developed by a medical doctor, the iHeart method of measuring aortic stiffness has been validated against the gold standard of aortic stiffness testing. iHeart is not a medical device. It is intended to be used for personal health and wellness education.

With medical device certification iHeart would be useful to medical clinicians for stratification of cardiovascular health risk.
