As the saying goes, “the best gear is the gear you’ll actually use.” Nowhere does this apply more than with your fitness tracker, which you need to wear constantly to monitor your step count, heart rate, and sleep quality. Studies might be mixed on their benefits, but fitness watches have longer battery life, better software, and more stylish designs than ever before. We’ve tested dozens over the past three years to bring you these picks.

It’s worth noting that Apple recently debuted the Watch Series 6 and Watch SE, which we’re testing at the moment alongside new Fitbit, Samsung, and Garmin watches. Looking for more options? Check out our guides to the Best Smartwatches and Best Running Gear.

Updated September 2020: We added new trackers and watches, such as the Oura Ring.
