Product Details

Fitbit Flex Black, Model FB401BK

Features:

  • 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
    • Calories Burned
    • Hours Slept
    • Distance Traveled
    • Active Minutes
    • 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 quality. 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.
  • Share and compete with friends
    Challenge and compete with friends and family on Fitbit.com. In addition to rooting for one another, you can compare stats and see how your progress stacks up.
  • Flexibility to match your style
    Flex tracker is flexible. You can take this tiny tracker out and put into any of Flex's colorful bands to fit your mood. Check out our accessory band colors and look good no matter what you're wearing.
  • Plays well with other apps
    Weight trends can be influenced by a variety of fitness and nutrition factors. Fitbit works with several popular health apps that let you export your Fitbit data their way. Some, like Lose It!, also let you import their data into your Fitbit dashboard, so you can track your stats in either location. Learn more in our App Gallery.

Specifcations:

Controls & Display

  • Flex uses five white LED indicator lights to show you how your day is stacking up against your goals. Each light represents 20% of your goal. Just tap the display twice to see your progress against your daily goal.

Wireless sync to PC & Mac

  • Fitbit's trackers are the first all day activity trackers to offer Bluetooth 4.0 connectivity, so you see your stats in real-time. Syncing occurs automatically any time Flex is within about 20 feet of the wireless sync dongle and is relatively motionless. The dongle plugs into your Mac or PC's USB port. Syncing and uploading require use of the Fitbit Connect application

Wireless sync to mobile

  • Syncing Flex to your smartphone or tablet requires Bluetooth 4.0 compatibility.
    This is currently available on:
    • iPhone 4S, 5
    • iPad 3, Retina
    • iPad mini
    • iPod touch, 5th generation
    • Samsung Galaxy S4
    • Samsung Galaxy S III
    • Samsung Galaxy Note II
    • Samsung Galaxy Note 10.1

Memory

  • We recommend syncing your data regularly. As long as Flex has battery power, it tracks the most recent seven days of detailed, minute-by-minute data. It also tracks your daily total for the past 30 days and summarizes your daily calories, distance, and steps taken.

Batteries & Power

  • Flex battery lasts approximately five days when fully charged. When charging your Flex the LED lights will indicate its level of charge. All 5 lights will light up when it's fully charged. You can also see your battery level on your Dashboard and mobile application. Remember to charge your Flex every 3 to 5 days to ensure you are always tracking.
  • Battery Life: 5 days
  • Battery Type: Lithium-polymer
  • Radio Transceiver (For Wireless Sync): Bluetooth 4.0

    This was great to show my husband I'm a restless sleeper. I still need to enter the stuff for the calorie count, but it is a great tool. An added bonus is the alarm I can use to either wake up or if I have something scheduled during the day.

    I love my fit flex, but I am frustrated with the controls. Last night it told me I had only slept 20 minutes. This is because the control got changed somehow. I have ordered the fit Force to solve this problem. If you are ordering a new item - put out the money for the Force, unless you are only using it for the pedometer, which works great. I am giving mine to my daughter who runs and is not worried about tracking her whole day for diet reasons.

            This is a smart pedometer, not accurate, you have to log every activity like your food, time to go to bed, to getup from bed etc.
            Not working for iPhone 4, not for mini iPad, not for Samsung tablets, not for many phones, only limited phones. On computers XP hard to set up, only for 7 or 8. I swim with it,good for time battery.
