Our Take

The Oura Ring Gen 3 is a titanium smart ring that tracks sleep, activity, heart rate variability, and body temperature from your finger. It's one of the most accurate sleep trackers available, measuring sleep stages, blood oxygen levels, and resting heart rate in a form factor that's significantly more comfortable to wear overnight than a wrist-based tracker. The new Daytime Stress and Resilience features make it a comprehensive health monitoring tool.

The Verdict

4.4

The Oura Ring is the best sleep tracker you can buy. The combination of comfort, accuracy, and week-long battery life makes it a genuine health tool rather than a gadget. While the subscription model is frustrating, the data quality justifies the ongoing cost for those serious about understanding their body.
