Fitbit Flex Wireless Activity & Sleep Wristband

Don't leave home without this slim and stylish device. The Fitbit Flex Wireless Activity & Sleep Wristband tracks your steps, distance and calories burned during the day and at night, it tracks your sleep quality and silently wakes you in the morning. The 5 LED indicator lights show you how you are tracking towards your personal goal so you are motivated to get out and be more active.


Set a goal and get moving

Choosing between steps, calories or distance, set your goal and allow the LED indicator lights to show how you're tracking. Each light represents 20% of your goal.

What is tracked?

Powered by a leading-edge accelerometer, Flex bases calculations like calories burned on your personal profile reflecting your stats. Measurements include steps taken, calories burned, hours slept, distance travelled, active minutes and quality of sleep.

Helps you sleep

Flex never sleeps, even when you do. At night, Flex tracks how long and how well you slept as well as how may times you wake up. In the morning it wakes you with a silent alarm which won't bother anyone else.

Always with you

Easy to wear and water resistant, it fits comfortably around your wrist so you can wear it all the time.

Sync your stats for progress updates

Get real-time access to your stats on the Fitbit dashboard throughout the day. Flex automatically syncs your data to PCs, Macs, many iOS devices and selected Android phones via Bluetooth. Also works with NFC-enabled Android devices so you can tap and go.
