Understand your body better with the Oura Ring 5. Its discreet sensors accurately track over 50 metrics, giving you valuable insights into your health and wellbeing. Plus, it looks and feels just like a normal ring, so it fits seamlessly with your style. Its all-titanium design is thinner, lighter and 40% smaller than the Ring 4. It's built to be tough without weighing you down. And with an Oura Membership (sold separately), you can access features like in-depth sleep analysis, personalised health insights and live heart rate monitoring. You even get the first month free if you're signing up for the first time.

Please note:
- To find the most comfortable fit, we recommend purchasing the Oura Ring 5 Sizing Kit. Sizing differs from Gen 4 and standard ring sizes, so if you're switching rings or are unsure, use the correct kit. Wear the sizer for 24 hours to find your best fit.
