The newest device from Fitbit is the Fitbit Flex wireless activity and sleep wristband. Part of the company’s new smart devices to help users achieve health and fitness goals, the Fitbit Flex allows users to monitor sleep and track activity. The simple wristband is made of silicone and includes a small, removable sensor that tracks the user’s motions. With the embedded accelerometer, the Flex responds to taps by illuminating LEDs to show progress towards a daily goal. Tapping the device three times turns on sleep tracking and the device includes a silent alarm. Daily stats are updated on the Fitbit app for Android or iOS where users can set goals, track weight or log food.
