Verdict

The Fitbit Charge 6 is a fitness band for people who want training data without a smartwatch on their wrist. The built-in GPS means you can leave your phone at home on a run and still get a route and pace, which is the feature that separates it from cheaper bands. Heart rate, SpO2 and sleep tracking are included, and the colour AMOLED screen is small but readable. Battery life is claimed at up to 7 days, which is the practical advantage over a smartwatch: you charge it weekly, not nightly. Google Maps and Wallet support add a little everyday utility.

The compromises are the familiar Fitbit ones. Some of the deeper insights sit behind Fitbit Premium, the screen is too small for serious app use, and the strap is proprietary. This is not a smartwatch and should not be bought as one. It is a training and sleep tracker that happens to show notifications.

For runners, walkers and anyone who wants a week of battery life, the Charge 6 is a strong middle ground. For iPhone owners who want apps and a large display, the Apple Watch is the better fit. Buy the Charge 6 for the GPS and the battery, not for the ecosystem. The screen is bright enough outdoors, and the band is comfortable enough to sleep in, which matters if you want sleep tracking to be useful rather than occasional. It is also a good choice if you want Google Maps directions on your wrist without buying a smartwatch.
