Make fitness a lifestyle with Flex!
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.
Powered by fitbit's leading-edge accelerometer, the Flex bases calculations like calories burned on your personal profile — reflecting your stats, not any average Joe's. It is water resistant and should be able to brave all the elements of your everyday life - whether you're in the shower or out in the rain, submergible up to 10 meters.
The Flex Tracks:
- Steps taken
- Distance traveled
- Calories burned
- Active minutes
- Hours slept
- Quality of sleep
It syncs automatically your data to PCs, Macs, many iOS devices and select Android phones without plugging in or pushing buttons. This gives you real-time access to your stats on the fitbit dashboard throughout the day. Syncing occurs automatically any time the Flex is within about 6 meters of the wireless sync dongle and is relatively motionless. The dongle plugs into your Mac or PC's USB port.
