Make fitness a lifestyle with Flex™.
FLEX™ WIRELESS ACTIVITY AND 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.
Set a goal and go
Flex allows you to set a goal and uses LED lights to show how you're stacking up. Each light represents 20% of your goal. You choose which one — steps, calories, or distance. It lights up like a scoreboard, challenging you to be more active day after day.
FLEX TRACKS:
- Steps taken
- Distance traveled
- Calories burned
- Active minutes
- Hours slept
- 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.
