The red Fitbit Flex Wireless Activity and Sleep Tracker Wristband is a water resistant band that you wear on your wrist to track vital daily stats. It tracks your steps taken, distance, and calories burned. It also measures your sleep quality and has a silent alarm that vibrates to wake you up - rather than beeping which could wake others. The Flex features Bluetooth 4.0, so it syncs wirelessly with your devices automatically whenever it is within 20' of them. Both a small and large wristband are included to ensure a comfortable fit, as well as a wireless sync dongle and charging cable.

Set Your Goals
Flex allows you to set a goal and uses LED lights to show how you're stacking up. Each light represents 20% of your goal. You choose which one - steps, calories, or distance. It lights up like a scoreboard, challenging you to be more active day after day
Flex tracks your steps taken, distance traveled, calories burned, active minutes, hours slept and the quality of your sleep. It's powered by Fitbit's accelerometer, and bases calculations ilke calories burned on your personal profile - reflecting your customized stats
Helps You Get Better Sleep
Flex is always on. Slip it into your wrist band at night, and it'll measure your sleep quality. 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. Your Flex also has a silent wake alarm that gently vibrates to wake you at your desired time, without disturbing your partner. At night it tracks how long and well you sleep, and how many times you wake up. In the morning, it wakes you with a silent alarm that won't bother your partner
