I just learned about a new health tracking device on Kickstarter called FlyFit...Instead of being a wrist bracelet, the FlyFit attaches to your ankle. This way, it tracks your leg's movement instead of your arm, and works with your iPhone or Android (Kit Kat OS or later) phone. The benefit: by attaching your your ankle, the FlyFit can track running, walking, cycling, stationary biking, swimming as well as your sleep. And it tracks stair climbing too.
