This tracker records the number of steps you take and stairs you climb, calculating how far you travel, how many calories you burn, and how much daily time you spend active. The information it records is sent wirelessly to your smartphone and/or computer, so you can learn more about your habits over time. The front of the One features an OLED display that shows your daily stats and time of day. The device is water-resistant and its battery lasts for 10 to 14 days on a single charge, which takes one to two hours. It clips securely to your pocket, belt, or other article of clothing, and includes a wristband for sleep tracking. Also included are a USB dongle for wirelessly syncing with your computer, a charging cable, and a silicone clip. Sleep Management Measure your sleep duration and quality at night by inserting your One into the included sleep wristband. You can also wake up to a silent alarm that rousts you with a gentle vibration. Wireless Sync The included USB dongle lets you sync your One to your computer, and the Fitbit smartphone app lets you sync your One to your Android, iOS, or Windows Phone device. You can see your progress in easy-to-read charts and graphs on your computer or mobile device. Free App The Fitbit app lets you view your progress and analyze your trends on your mobile device and computer. You can also share your progress and compete against friends, and earn badges for your effort. A barcode scanner, calorie estimator, and food database let you log meals for a more accurate picture of your calorie burn, and workout logging with MobileRun gives you deeper insight into your exercise.
