The Oura Ring 4 is a titanium smart ring that tracks sleep, heart rate, blood oxygen and daytime activity, then scores your readiness and stress in the Oura app. It is the slimmest, most comfortable Oura yet, with recessed sensors and up to eight days of battery. It suits people who want health tracking without a screen on their wrist, and it beats most smartwatches on sleep detail and wear comfort. Reviewers praise the sleep insights and build quality but say the subscription is required for real value and that step and workout tracking lag behind a watch.
