Smart rings monitor your health in a tiny, inconspicuous package. At first glance, they look like any other piece of jewelry, a simple gold or silver ring. But with tiny sensors, these rings track biometrics through your finger. Yes, they'll track your step count and calories burned, but more advanced technology allows them to track sleep and stress levels, all detected through heart rate and variability.

After extensive testing — including some epic marathon training — we selected the best smart rings of the year so far. This year, Oura debuted the Oura Ring 5, which is an exceptional ring for comfort, design, and overall health tracking. While it takes the top spot in our guide, we tried plenty more options.

This guide compares the top options for fitness-minded tech users who want a low-profile health tracker. To compare the rings, we dug into what actually separates these rings: design, battery life, health features, price, subscription costs, and device compatibility.

As of August 2026, we've replaced the Oura Ring 4 with the Oura Ring 5. Yes, it's the latest model, but its smaller size has greatly improved its comfort, making it the best Oura Ring but also the best overall smart ring.

We've also removed the Evie Ring from this list as it appears to be out of stock. The website for the Evie Ring appears to be unavailable, and the product is no longer listed for sale. We've reached out to Evie for comment on whether the ring is officially discontinued and the status of the company.
