If you want a fitness tracker you can wear (almost) anywhere, you have to get a Whoop. The tracker is a little mechanism with a hook that can be strapped onto the wrist band, but Whoop sells apparel that helps you fit it around your bicep. You can even put it in a pocket in your gym shorts if wearable isn’t quite your vibe. Like a smart ring, there is no screen, which means you need a pretty damn good app. Whoop’s app checks all the boxes and presents a bunch of information cleanly and readably, with emphasis on what’s most important.
Wearability isn’t the only thing that makes the Whoop band a versatile tracker. Due to its form factor, it’s excellent for cardio workouts but the app also has a bunch of strength training options. As long as you can get whatever you’re doing to get your heart pumping, the Whoop will record it for you. The MG in this top-of-the-line version I’ve tested stands for “medical grade,” which gets into a whole world of hoops to jump through and certifications to be made. In short, it’s some of the most advanced monitoring you’ll find in one of these trackers.
The caveat is it’s more a subscription than other devices. Once that first year is up, you have to pay the multi-hundred dollar subscription fee to keep using the device.
