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 other’s progress
• Rain-, splash-, and sweatproof so you can wear it all the time (but not in the pool; unfortunately, it’s not fully waterproof)
• Rechargeable Li-ion polymer battery typically lasts about 5 days per charge
• Data syncs automatically and wirelessly to your computer, iPhone (4S or 5), iPod touch, iPad (3, Retina, or mini), and select Android phones
