Oura Ring

The Oura Ring is a line of smart rings made by Oura Health, a Finnish health technology company. Worn on the finger, the rings use optical heart-rate, temperature and motion sensors to track sleep, heart rate, heart rate variability, activity and readiness, shown in the Oura app. Several generations have been released, most recently the Oura Ring 4 and the Oura Ring 5, which went on sale in June 2026. Most of the app's insights require a paid Oura membership.
