An ultra-thin, waterproof fitness wristband with detachable tracker that can easily be inserted into one of the additional wristbands or pendants. So you can record your daily activities as well as your sleep in style - no matter which outfit you choose.

Track your footsteps, distance traveled, calories burned, active minutes, hourly activities and standstill time.

Automatically record workouts such as running, aerobics and other sports, and then view the summaries in the Fitbit app.

Automatically record your sleep quality and length, set a sleep goal and sleep time reminder to create good habits, and wake up gently in the morning with a silent vibration alarm.

Record swimming and see your summary in the Fitbit app. Whether a bubble bath or a day on the beach - you don't have to worry about wetness.

When you receive calls or text messages, the Flex 2 vibrates and the discrete LED display lights up color-coded lights so you don't miss any important messages.

To keep you active all day long, the Flex 2 sends you a reminder of your movements that prompts you to take 250 steps per hour.

With a battery life of up to 5 days*, this ultra-thin tracker records day and night without you having to charge it.

When your Fitbit Flex 2 is fully charged, the battery will last up to 5 days. Note: Actual battery life and charge cycle may vary depending on usage, settings, and other factors.
