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. The One doesn't nap, even when you do. Slip it into your wrist band at night, and it'll 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, 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. 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. 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 Fitbit.com and register your device (which you can also do via select smartphones). Your stats will sync on their own, giving you real-time access to all that outstanding data on your Fitbit dashboard.
