Oura Ring Gen3 Horizon ($359, originally $449)

It’s no surprise that Jennifer Aniston endorses the Oura Ring. The fitness tracker is her go-to to monitor her sleeping patterns, and it’s worked wonders. “I struggle with sleep, so it’s something that allows me to really track how that’s going,” she told Popsugar in a previous interview. “You can either start your day off feeling incredible or it will just tell you how crappy you did — like, first thing out of the gate, you get a 60 sleep score.” It also can monitor your heart rate, stress level, activity, and more. Get even more details in our editor’s review of the Oura Ring.

Looking for the newest model? The Oura Ring 4 ($297, originally $349) has many of the same capabilities, along with extended battery life, a more comfortable fit, and improved sensing technology.

Editor Quote: “In summary, I really like my Oura Ring. I find the data very helpful, and it lets me know how to make minor tweaks to support my overall health and wellness goals. It’s not going to tell you anything unprecedented; after a turbulent red-eye last night, it’s no wonder my sleep score was abysmal, and I’ve had lots of coffee to keep up. But, for someone that generally leads a healthy lifestyle or is looking for clues to improve their everyday habits like sleep and movement, I’d highly recommend the Oura Ring.” — India Yaffe, former associate editor, Shopping
