Fitbit is a top manufacturer of activity trackers, and reviewers say the clip-on Fitbit One leads the pack. Experts call it "one of the most advanced fitness trackers money can buy." Uploading data is convenient, with Bluetooth connectivity and compatibility with many devices, including mobile apps for iOS and Android. Fitbit offers additional tracking features and support on a free web account.
Bright screen provides instant feedback. Reviews find the Fitbit One's OLED screen sharp and easy to read. Experts like its motivational messages -- urging you to get active or go faster -- and appreciate the flower icon, which grows with your daily progress. With the included wristband, users can wear the One at night to track sleep quality; a vibrating alarm provides a noiseless wake-up call. Danny Sullivan with CNET notes the Fitbit One is step-centric, so users who enjoy a lot of non-step activities (like bicycling, skating and paddle-boarding) must manually log in activities on their web account.
Accurate measuring. In side-by-side tests, experts report the Fitbit One is very accurate for tracking calories, stairs and steps. Users report the unit occasionally gets confused with altitude changes other than climbing stairs. The One is compatible with a wide range of devices: the included wireless dongle connects to PC and Mac computers, and a Bluetooth connection links with compatible smartphones. A free account at Fitbit.com graphs biometrics, rewards accomplishments with badges and encourages friendly competition. Editors at CNET explain, "To take fitness beyond casually logging workouts, runs, and walks, the Fitbit service lets you enter the food and drinks you consume."
Compact clip-on design. In a review for Time magazine, Ben Taylor calls the Fitbit One "size-efficient." "Weighing a mere eight grams, the tracker sports more options and better syncing than alternatives four times its weight," says Taylor. Jill Duffy of PCMag.com notes you can "clip the Fitbit anywhere on your clothes, or remove the casing and slip it right inside your pocket, handbag, or bra, as it will track your activity just about anywhere you place it." Some consumer and expert reviewers, including editors at CNET, say the Fitbit may be too small and warn it may be easy to lose. The built-in battery lasts about a week between charges.
In this test of 14 activity trackers, the Fitbit One earns an Editor's Choice award, tying with the Withings Pulse as the best activity tracker. Jill Duffy praises its sleek design, comfort and accuracy, recommending it as the best fitness tracker for non-athletes.

Danny Sullivan tests the Fitbit One alongside the Jawbone UP, Nike+ FuelBand and BodyMedia FIT. He appreciates Fitbit's companion website, which logs food intake and extra activities to provide a complete health picture, but finds the One's design is too limited to step activities like walking and climbing stairs.
