Jaybird Reign

Reign labels itself primarily as a recovery band. It tracks your heart rate variability, activity, and sleep patterns to help you meet your goals and stay on top form. The ‘Go Zone’ gives you a score every morning, which tells you how ready your body is for activity, so you know how hard to push yourself. It enables you to know and understand your body from the inside out. Also, you can track and view all of your data on graphs and compare progress. Reign can also distinguish which exercises you are finding difficult, and then coaches you to your maximum effort. What more could you ask for?
