The Best Fitness Trackers

Wrist-worn fitness trackers that can monitor your steps and heart rate were once seen as cutting-edge devices. Now these wearables are becoming more high-tech with each release, equipped with features like personalized workout programs and the advertised ability to monitor stress or sleep quality.

Since 2015, we’ve been running, walking, swimming, cycling, sleeping, and basically living with 46 different fitness trackers day and night, to assess their accuracy, ease of use, and comfort. Although no tracker perfectly recorded every metric we tested, we found that the simply designed yet feature-packed Fitbit Inspire 3 is the best option for most people who want to monitor their activities, with metrics like distance traveled, step count, heart rate, and estimated calories burned.

The Fitbit Inspire 3 was the most accurate fitness tracker for step count and near the top of the rankings for every other test we performed. The touchscreen display is only 1.5 inches tall but is simple to navigate, thanks to its sharp colors and easily readable text and icons. The thin, half-inch band doesn’t feel clunky during workouts or everyday use, and the Inspire 3 weighs just 0.32 ounce—lighter than a typical USB flash drive.

Fitbit has a free app where you can connect with other Fitbit users, log information to learn about stress management, and dig deeper into data such as heart-rate history (a premium version of the app costs $10 per month or $80 per year) and offers access to apps like Calm for sleep and meditation). The Inspire 3’s battery is advertised as lasting 10 days before charging, although we found it to come in a fair bit short of that mark.

Battery life: up to 10 days
Water resistance: yes, for up to 50 meters
GPS: when connected to a phone

Runner-up

The latest version of the Charge series continues a tradition of accurate activity tracking, but many of the new additions require Google integration.

The Fitbit Charge 6 offers a few upgrades from the Charge 5 , which we previously recommended as a runner-up pick. The most notable upgrade is a haptic side button that allows for easier screen navigation than swiping on the touchscreen (which, we found, sometimes isn’t responsive). The Charge 6 also has built-in GPS, which the Inspire 3 doesn’t have, in addition to access to Google Maps, Google Wallet, and YouTube Music (with subscription). But when it comes to tracking distance, the Inspire 3 performed better in our tests.

Battery life: up to seven days
Water resistance: yes, for up to 50 meters
GPS: built in

Also great

The Apple Watch SE delivers some of the most precise readouts and—with a mobile plan—can be used for calls and messaging. But its battery life is much shorter than that of our Fitbit picks.

The second-generation Apple Watch SE has a vibrant, clear display and the best intuitive touchscreen of the devices we tested. Even if you’re not connected to an iPhone, you can take advantage of a large library of apps. Performance-wise, the Apple Watch SE—also our budget pick smartwatch for iPhone users—accurately measured heart rate, steps, and distance. But for people who want to go on a run and just track, say, their pace and distance, the Apple Watch SE might be overkill, especially given its higher price and limited battery life.

Battery life: up to 18 hours
Water resistance: yes, up to 50 meters
