The lavender Fitbit Flex 2 is a water-resistant, all-day activity and sport tracker that can be on your wrist or, using a separately pendant, around your neck. This stylish accessory tracks your steps, distance, calories burned, and more. It utilizes SmartTrack technology to automatically detect activities like running, sports, and aerobic workouts, then sends those exercise summaries to the Fitbit app for review. Additionally, the Flex 2 automatically measures your sleep quality and features a silent alarm that vibrates to wake you up, rather than beeping which could wake others.

The Flex 2 uses Bluetooth 4.0 LE to sync your data wirelessly with compatible devices whenever it's within 20' of them. Bluetooth also allows you to receive smart notifications whenever you receive a call or text. Both small and large wristbands are included to ensure a comfortable fit, as is a charging cable.
