Oura Ring 4 is a competitive sleep tracker with insights on sleep efficiency, rest, preparation, latency and more. I’ve been using woolering for a while, and it not only gives me a deeper insight into my sleep, but also supplements those data points with the explanations behind the numbers. Wella claims to accurately track sleep cycles, total sleep duration, resting heart rate, heart rate variability, and movement.
These features were enhanced by the deployment of the fourth-generation uranium ring that came to the market in October. Oura Ring 4 has a smart sensor that allows for more accurate and continuous data capture. It also has a flat sensor that is more comfortable than the Oura Ring 3 and makes it easier to wear over time.

Every morning I got my last night’s sleep score and suggested my heart rate, sleep efficiency, and my bedtime range for the day. Sleep scores help me understand my energy levels and my activity bandwidth for the day, such as whether I should exercise or rest. Welling can also detect the shortest nap and take them into consideration in your sleep score for the day. Plus, the app’s sleep tab provides information on sleep efficiency, rest, REM, deep sleep, latency and timing, so you don’t just dig deep and see how much time you spend in bed with just your sleep score.
As if Oura Ring doesn’t have enough sleep-friendly features, Oura has announced a body clock feature that teaches users more about circadian rhythms and body clocks. This feature measures sleep chronotypes calculated by body temperature, sleep wake cycle, and physical activity. Through this data I learned in the middle of the night that I was the most productive.

The battery life is excellent. It will be billed promptly and charged for about 5-6 days. Wella says the new generation’s battery life lasts for 8 days, but my testing didn’t tell me it was. The downside of the ring is the extra $72 I spend on a Wella subscription each year, plus the $350 I spend on the ring itself.
Redditors also agree that Oura Ring as a Sleep Tracker is valuable. “If you’re struggling with sleep quality, overtraining, or anything else that affects your recovery, you say it’s worth it,” one user wrote in the thread. However, one Best Buy reviewer noted that the rings do not have half sizes. This can be a problem if your fingers are swollen.
