11 Must Have iPhone Apps for Fitness

Cardiio iphone app review

7. Cardiio

Cardiio is an impressive app that tracks your heart rate throughout a workout—by using the phone on your camera. While most heart rate monitoring apps require another piece of hardware that gathers the data, Cardiio tracks heart rate by visually measuring the blood volume in your face, tracking minute changes in reflective light to find out how fast your heart is working. The app also analyzes the data it collects, giving you insight into your overall health and fitness level.
