Nike+ FuelBand tracks your activity through a sport-tested accelerometer, then translates every move into NikeFuel. It's also a great watch. Nike+ FuelBand tracks running, walking, dancing, basketball and dozens of everyday activities. How active do you want to be? Set your Daily Goal and Nike+ FuelBand tracks your progress, lighting up from red to green throughout the day. Get to green and you've hit your goal. With the touch of a button you can cycle through your time, NikeFuel earned, steps taken and calories burned. Challenge yourself to capture records, reach new milestones and unlock special achievements. Go on a streak by seeing how many days in a row you can get to green. Wirelessly sync your Nike+ FuelBand to visualize your results. Or plug it directly into your computer's USB port to sync. See your peaks, your progress and your trophies. Get the free Nike+ FuelBand mobile app to sync wirelessly, track your progress and get extra motivation on the go. With the app you can compete with yourself or share results with your friends to compare, compete and celebrate. To accommodate a range of wrist sizes, each Nike+ FuelBand comes with two easy-to-insert links (8 mm and 16 mm). Wear it without the inserts for the minimum size or add a link to make it larger.
