Fitbit Flex blauw

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 cycle 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.

Helps you get your ZZZs
Flex never sleeps, even when you do. Continue to wear it all night and it’ll measure your sleep cycle. Your dashboard will reveal how long you slept and the number of times you woke up to help you learn how to sleep more soundly. Flex also has a silent wake alarm that gently vibrates to wake you at your desired time, without disturbing your partner.

Always by your side
Flex is your perfect companion. It fits comfortably around your wrist so you can wear it proudly all day and night.

Sync your stats. See your progress
Flex automatically syncs your data to PCs, Macs, iPhone 4S & 5, iPad 3, Retina & mini, iPod touch, and to 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. Also with select NFC-enabled Android devices, you can tap your device to launch your Fitbit stats. It's like magic.

Discover your trends
Flex comes with free online tools and a mobile app that allow you to set goals and follow your progress through awesome graphs and charts.
Log food, workouts and much more and get the inside scoop on your health. Knowing how close you are to reaching your goals gives you the motivation to reach them and aim higher.

Badges galore
We’ll sing your praises and keep you motivated with Fitbit badges for daily, weekly, even lifetime achievements. Each time you achieve a new goal, or “wow” us with your performance, we’ll award you with a badge. But you’ll have to work for it.
