Charge HR Wireless Activity & Heart Rate Tracker

A sleek, sporty wristband motivates you to achieve your fitness goals by calculating steps taken, calories burned, elevation climbed and distance traveled throughout the day and features a low-profile display to indicate your real-time progress. The Charge wirelessly syncs your stats to your computer or smartphone, then measures hours and quality of sleep before silently waking you with a vibrating alarm in the morning. PurePulse heart rate monitoring keeps a continuous tab on your heart rate and offers simplified rate zones for easy tracking. The included mobile app lets you track your food intake, graph your progress and watch for important trends across time, helping you achieve your training, sleep and fitness goals. You can also choose to compete with friends on the Fitbit leaderboard. The band displays caller ID when your smartphone is nearby, allowing you to screen incoming contacts during workouts so that you never miss an important call.
