Fitbit Flex: The Wireless Activity and Sleep Tracker for Your Wrist


Whether you’re an exercise beast or a workout slacker who needs to get into shape, Fitbit’s tracker gadget — Flex — can help you exercise, sleep, and eat smarter.

Flex is the latest Fitbit product aimed to help people live a healthier lifestyle. Of the group–comprised of two wireless activity and sleep trackers and a Wi-Fi smart scale–the water-resistant silicone Flex also doubles as an accessory, for your wrist.

Fitness trackers are everywhere, and Flex isn’t even the only wristband tracker on the market right now; Jawbone and Nike sell them too.

But as New York Times‘ David Pogue notes, Flex makes up for what its competitors lack: it’s the first wristband to use Bluetooth 4.0 to sync data in real-time to mobile devices and computers, and it tracks both activity and sleep.

“We’re aware that there is no ‘one size fits all’ option in fitness, so Fitbit wants to offer the widest variety on the market,” says James Park, CEO and co-founder  of Fitbit. “When we saw that we could bring our knowledge to a wristband format done right, we had to create the new Flex.”

Overall, Flex is an analytical data tool with incredible insight on how your body is functioning. LED lights on the wristband indicate how close you are to achieving the goals you set on the app. It tracks: steps taken, distance travelled, calories burned, active minutes, hours slept, and the quality of sleep, including the number of hours and number of times you wake up. It also features a silent alarm that vibrates to wake you up gently.

While the wristband itself doesn’t have functionality that tracks what you eat and how much you weigh, easy-to-navigate charts and tools also allow you to log all of this info on the app or site to better determine the progress you’re making.

Plus, Flex comes in at least four colors, so you can remove the tiny tracker from the interchangeable bands and match, if you’re into that sort of thing.

Pre-orders for a spring delivery can now be made from the Fitbit store.
