We’ve tested and reviewed a lot of the best sleep trackers, but the Oura ring continues to come out on top—and experts agree. On a recent episode of the mindbodygreen podcast, psychiatrist, and neuroscientist Dave Rabin, M.D., Ph.D., called the Oura ring the “most accurate consumer wearable,” explaining that “HRV is one of the most accurate measures of resilience in the body, and it’s impacted by things like getting great deep sleep.” 

Research backs the ring’s accuracy, too. When compared to a comprehensive medical test used to diagnose sleep disorders (the polysomnography test), the Oura ring showed accuracy levels of up to 92.6%.

Oura is also constantly updating its technology, with close attention to how to more accurately measure metrics like HRV, body temperature, and time spent in different sleep cycles: light sleep, REM sleep, and deep sleep. With this data, the app provides you with a daily sleep score, activity score, and readiness score, along with expert- and science-backed tips to optimize your health and well-being.

The readiness score, for example, is provided in the morning and helps you decide whether you want to opt for an intense workout or prioritize rest and relaxation to help your body and mind recover. The sleep score measures how well you slept, taking into account the total time spent in bed, the time in each sleep stage, your resting heart rate, HRV, restfulness, and more. And the ring gives more holistic insights than just sleep.

It’s also a fitness tracker, accurately measuring your steps, workouts, training volume and frequency, as well as any time spent inactive or recovering. All metrics are viewable in the brand’s app, which is easy to use and regularly updated as the technology is enhanced. It’s worth noting that I truly love the fact that this is a wearable without a screen because I certainly don’t need another screen in my life.

If you’re hesitant about a tracker that’s meant to be worn 24 hours a day, seven days a week, I felt the same way. I’ve wanted to dive into my sleep data for a while, but every wearable I tried felt like it would disturb my sleep more than it would help track it. The Oura ring is sleek and comfortable. I wear it as the brand recommends, on my pointer finger, without any disturbance to my sleep whatsoever. When you order the ring, you’ll first be sent a sizing kit, ensuring a fit that you’ll feel comfortable in (and one that will give the most accurate results).

Each morning, I look forward to viewing my sleep score and my readiness score, using these insights to think more deeply about my routines. Since getting the ring, I’ve adjusted the timing of my meals, played around with my sleep schedule, and experimented with different supplements. I’ve seen significant improvements in my sleep quality simply by leaning into the lessons from Oura. What’s more, I feel less stressed throughout the day, and I’ve been able to optimize my workouts by staying mindful of how much energy I have to give, and when I need to opt for a rest day. I’m also incredibly impressed by the ring’s battery life, which lasts up to seven days on one full charge (leaps and bounds above other trackers I’ve used). The ring is water-resistant up to 100 meters, too.
