Product Details

Fitbit One Wireless Activity & Sleep Tracker, Model FB103BK

If you want to turn fitness into a lifestyle, the One™ is for you. For starters, it never rests. During the day, it tracks your steps, distance, calories burned, and stairs climbed. Come nightfall, it measures your sleep quality, helps you learn how to sleep better, and wakes you in the morning. The One™ motivates you to reach your goals by bringing greater fitness into your life – seamlessly, socially, 24 hours a day.

Key Features:

  • A Lot Of Power, A Little Device
    Monitor your day with the One- this tracker's aim is to empower and encourage you by delivering real-time feedback that helps you be more active. Why not take the stairs instead of the elevator? Or go for a quick walk after lunch? Those steps will add up fast.
  • Helps You Get Your ZZZs
    The One doesn’t nap, even when you do. Slip it into your wrist band at night, and it’ll measure your sleep quality. Once the data syncs, graphs on your dashboard will reveal how long you slept and the number of times you woke up, giving you a sleep quality score. Over time, you can apply what you learn to help you sleep more soundly. The One™ also has a silent wake alarm that gently vibrates to wake you at your desired time, without disturbing your partner.
  • By Your Side, Day And Night
    Debuting in black and burgundy, the One™ is suitably  discreet. Wear it comfortably in your pocket, on a belt, or a  bra – the silicone clip will keep it secure. Use the sleep wrist  band at night. Its rechargeable battery lasts five to seven  days before needing a boost. The One™ is also rain, splash,  and sweat-proof, allowing you to brave the elements.
  • Syncs Your Stats For You
    The One automatically syncs your data to PCs, Macs, the iPhone 4S & 5, iPad 3, Retina & mini, iPod touch,  and select Android phones. All you need to do is sign up for your free account on and register your device (which you can also do via select smartphones). After that, voilà. Your stats will sync on their own, giving you real-time access to all that outstanding data on your Fitbit dashboard.
  • Paints A Picture Of Your Health
    Fitbit is full of graphs, charts, and tools designed to help you track your progress and understand your health and fitness. The customizable dashboard and mobile app (both free) bring all that digestible data to your fingertips. Knowing how close you are to reaching your goals gives you added incentive to achieve them, sleep better, 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 In addition to rooting for one another, you can compare stats and see how your progress stacks up.
  • Log Activities, Meals, & More
    Log your food, water, workouts, weight, and more using Fitbit’s online tools. If you’re on the move, use the mobile app to do the same. Our expansive database covers food and activities, which makes logging your info quick and easy. Create a Food Plan to eat smarter. Log an infinite number of activities, from walking the dog to swimming laps. Before you know it, you’ll have a complete picture of your progress.
  • Tuned Into Other Apps
    To further track your health, you can export your Fitbit data to several popular fitness apps. Some of them – including SparkPeople, Lose It!, MyFitnessPal, and MapMyFITNESS – let you import their data into Fitbit’s dashboard, so you can track and understand your health in either app. See what’s available in our App Gallery.
