The verdict
Our review
The Oura Ring 4 remains the reference smart ring. Sensor accuracy improved with the recessed sensor design, sizing is broader, and the app's AI Advisor answers questions about your own data in plain language.
It is the least intrusive way to get serious sleep and recovery tracking. The subscription is the ongoing cost of the best software in the category.
