What's the best way to track your progress? We've tested dozens of fitness trackers, spending hours on the treadmill, running, biking, swimming — even sleeping — and found that the Fitbit Charge 2 is the best overall choice for the money.
The Charge 2 is comfortable enough to wear all day, has a large screen and an interchangeable strap, continuously tracks your heart rate and automatically monitors your sleep without you having to lift a finger. Note that Fitbit released a firmware update that it says will improve the Charge 2's step-counting accuracy, so make sure yours is running with the latest version.
Those on a budget should consider trackers like the Fitbit One ($99), which tracks your steps, sleep, and calories, and can even automatically recognize some types of exercises. We chose this device after evaluating a dozen cheap fitness trackers. The Fitbit One lacks a heart rate monitor, but its discreet design that clips to your clothing makes it a perfect fit for fitness newbies.
For not much more money, you can get a tracker that gives you smartphone notifications that appear as text on your device. And if you're willing to spend $200 or more, other fitness trackers have special features such as GPS (great for runners who want to know their pace and distance). We've also evaluated the latest running watches.
To help you select the right fitness trackers for your needs, we’ve evaluated all of the latest models based on design, performance and ease of use. Here are our top picks—both high-end and budget—for each category.
How We Evaluate Fitness Trackers
For each new fitness tracker, we evaluate its hardware design and comfort. You need to be able to wear the device all day. We also evaluate the features, including movement detection (such as step counting and sleep monitoring), distance calculations and when applicable, GPS and heart rate accuracy. We test how well a device pairs with its companion app, and evaluate the experience of using the two together.
We also look to see what features the device's app supports, such as coaching and diet tracking, and if it can sync data with third-party apps, such as MyFitnessPal. Lastly, we wear the device for several days to a week to test the manufacturer's battery life claims.
