Helps you monitor your sleep patterns 

The One doesn’t nap, even when you do. Slip it into your wrist band at night and it will measure your sleep cycle. Once the data syncs, graphs on your dashboard will reveal how long you slept and the number of times you woke up - providing you with a sleep quality score. Over time, you can apply what you learn to help you sleep more soundly. The One also features a silent wake alarm, that gently vibrates to wake you up at your desired time - without disturbing your partner.

FitBit One - Charcoal

Easily clips to your clothing for any activity

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.

FitBit One - Charcoal

Syncs all your stats for you*

The One automatically syncs your data to PCs, Macs, the iPhone 4S+, the 3rd generation iPad and above, iPod Touch 5G, and select Android and Windows Phone handsets. 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.


*PLEASE NOTE: Fitbit is the first connected device to offer both Bluetooth 4.0 syncing to select iOS, Android and Windows Phone devices. Syncing is available on all iOS devices after the iPhone 4S. For Android, while many phones have a Bluetooth 4.0 chip, not all are able to be accessed by apps like Fitbit. Fitbit is working closely with phone manufacturers to try to develop syncing capabilities for more phones. Windows Phone app requires Windows Phone 8.1 and Bluetooth 4.0 LE or later. Please check here to see the latest devices with sync support.
