Make Fitness a lifestyle with Flex™.
FLEX™ WIRELESS ACTIVITY & SLEEP WRISTBAND
This slim, stylish device is with you all the time. During the day, it tracks steps, distance, and calories burned. At night, it tracks your sleep quality and wakes you silently in the morning. Just check out the lights to see how you stack up against your personal goal. It’s the motivation you need to get out and be more active.
QUALITY OF SLEEP
Powered by Fitbit's leading-edge accelerometer, Flex bases calculations like calories burned on your personal profile — reflecting your stats, not any average Joe's.
