A slim and stylish device that stays with you at all times, the Fitbit Flex keeps track of steps taken, distance traveled, calories burned, and your sleep cycle to help you reach your personal fitness goals.
Tracks steps, distance, calories burned, and total active minutes using a MEMS 3-axis accelerometer for the most accurate data
Also tracks how long you sleep and how many times you wake up; silent alarm gently wakes you in the morning without disturbing anyone else
Five LED indicator lights communicate a variety of feedback, such as goal progress, battery life, and sleep mode
Fitbit free mobile app and free online dashboard let you see your stats as graphs or charts so you know exactly how close you are to reaching your personalized weekly fitness goals ~ Fitbit helps keep you motivated by awarding badges when you achieve a goal ~ Connect with friends and family on Fitbit.com so you can see each others progress
