Fitbit Flex

The Good The Fitbit Flex is a simple way to track steps, sleep, and calories. The Flex's strap design makes it light and comfortable to wear. It also offers handy Bluetooth syncing, and Fitbit’s platform gives plenty ways to analyze your stats.

The Bad Clasping the Fitbit Flex’s strap shut is tricky. Direct syncing is only available with the iPhone, the Samsung GS3, and the Galaxy Note handsets.

The Bottom Line A long list of features and a comfortable fit make Fitbit’s new Flex the best fitness tracker you can buy.

A most versatile, feature-packed tracker

Editors' note (August 29, 2016): Fitbit has announced the Flex 2, an updated fitness tracker that's smaller, water-resistant and more fashion-forward than its predecessor. The Flex 2 replaces the original Flex reviewed here in Fitbit's lineup.

The $99.95 Fitbit Flex is the newest personal fitness tracker in the company's lineup. While the Flex isn't without some flaws, the gadget is the most complete product of its kind you can buy. It can track steps taken, sleep quality, and it syncs data wirelessly with PCs and Macs automatically. Comfortable to wear, the Flex can communicate directly with iPhones and select Android smartphones, and is water-resistant as well. Going head-to-head with other wristband-style exercise products such as the Nike FuelBand and Jawbone Up, the Flex offers more features and convenience at a lower price than those more expensive devices.

Design
When I first picked up the new Fitbit Flex, I initially considered its unadorned surface and clean, ring shape spartan. After all, the device lacks a real screen capable of displaying alphanumeric characters. Instead the Flex sports a thin sliver of a display cut from smoky dark plastic. Underneath the plastic sits a row of five tiny, white LEDs that blink to indicate the Flex's status.
