The Whoop is one of the most loved activity trackers in the fitness community and for good reasons: It is incredibly accurate. It tracks your activity and rest with the most accuracy we’ve seen, which makes its recovery features really shine. That’s part of what makes athletes love this so much: The app does the math for you, measuring how much energy you’ve exerted versus how much you’ve recovered and tell you how much movement to engage in the next day.

For a fitness tracker that doesn’t look anything like a fitness tracker, Withings is it. This wearable tracks your heart rate and steps, along with calories burned and distance traveled. Along with sleep cycle tracking, it also has an option for a vibrating alarm for a very gentle wakeup call. You can choose from a variety of face colors and watch bands to make it feel as personal to you as you want.

Fitbit’s latest, the Charge 6 fitness tracker, has one job: Track fitness. And you know, it does that job exceedingly well, with a precision that other trackers are still aiming to have. It’ll tell you your heart rate during activity, how well you’ve recovered after sleep, and when you’ve been sitting too long and could use an exercise snack.

If you’re training for a marathon, the Garmin Forerunner is the best you can get. It’s fast, accurate, and gives you the clearest data on how fast and far you’re running, as well as your energy exerted during it. The highly visible screen is both convenient for daily life and ensures you can stay safe and read that screen when you’re out in the elements.

Samsung’s latest galaxy watch has made some upgrades in its precision on tracking fitness, sleep, and heart rate, as well as making a longer lasting battery. Samsung improved its sensor, which helps give a better read on your heart rate and auto-recognizing your workouts as you begin them. Plus, you can also get an on-demand read of your body composition data.

Montblanc’s stainless steel and leather watch looks nothing like a wearable and everything like a very expensive watch, of which it is both. It is the best for tracking fitness, sleep, VO2Max, and recovery while you’re on the go or traveling a lot. It syncs up to the Timeshifter app, which provides feedback and advice on how to best prevent jet lag while traveling.

Sometimes you want all the add-ons and bonus features and sometimes, you really just want to know if you hit your 10,000 steps. For a simple, accurate, and reliable tracker that does its job well in a lightweight construction, the Fitbit Altra is it. It’ll track your heart rate and let you know once you’ve hit your preferred workout zones.
