The Fitbit Flex is slim and stylish, and tracks everything you do, all the time.
It’ll show you how many steps you took and how much distance you covered, how many calories were burned and how your activity matches up against predefined goals.
It’ll wake you up with a silent alarm that won’t disturb the person in bed next to you, and it’ll show you how long you were asleep.
The Fitbit Flex comes with a free smartphone app, and you can sync it with your computer and mobile devices.
