Oura Ring 5 Slims Down and Elevates Health Tracking, But Hits a Higher Price

The Oura Ring 5 is a sleeker successor to Ring 4, 40% smaller and weighing 2–2.69 g, with upgraded sensors (fewer optical paths, stronger LEDs, larger photodiode) delivering about 12% better overnight HRV and up to 19% better HR during workouts. It adds software features like a health radar, blood pressure signal monitoring, GLP-1 medication tracking, and external HR device integration, plus IP68 dust resistance and a 6–9 day battery life. Priced at $399 and with a reduced size range plus a required monthly subscription for advanced features, it may not justify upgrading for all Ring 4 users.
