The Fitbit One activity calculator helps you become more active, sleep better, and eat smarter. During the day, it tracks your steps, distance, calories burned, and stairs climbed. At night, it measures your sleep cycle to help you see how to sleep better; and it can even wake you in the morning without waking your partner.
Your stats upload wirelessly via computer, or select Bluetooth 4.0 devices (like the iPhone 4S and iPhone 5). Powered by your stats, you can set goals and track progress. Stay motivated by earning badges or connecting with friends for support or friendly competitions. Log food, workouts, and more. Bring greater fitness into your life—seamlessly, socially, 24 hours a day.
