How active are you ? Most of us have no idea how many calories we burn during our daily lives. Whatever your activity level, IRO allows you to track your daily energy expenditure with the touch of a button. The IRO bracelet, with its 3D accelerometer sensor and powerful software, tracks the movements of your wrist on a continuous 100-hour basis and shows you the corresponding color of the number of calories burned. Like the colors of the 7 chakras there are 7 color profiles on your IRO bracelet. Regardless of your age, sex or physical ability and whether you play video games with motion capture, tennis, go running or just run after the bus. From casual players to serious competitors and amateurs to professional sportsmen, IRO is for you!
