Oura Ring 5 Review: Refined Design and AI Health Coaching

Oura has released the Ring 5, a refined version of its smart ring that maintains leadership in the category. The ring is 40% smaller than the Ring 4, measuring 6.09 mm wide and 2.28 mm thick, with a tougher titanium coating and IP68 rating. Setup is straightforward, with sizes 6 through 13. Battery life averages six to nine days per charge. The biggest changes are in the app, featuring Oura Advisor, an AI-powered health assistant, and new predictive features like Health Radar, which includes Blood Pressure Signals and Nighttime Breathing. The ring now supports pairing with third-party heart rate monitors via Bluetooth, multiple rings on one account, and GLP-1 tracking. Privacy controls include time-based data deletion. Competitors like Samsung Galaxy Ring, Ultrahuman, and RingConn have narrowed the gap, but Oura still offers the strongest software experience, though a $6-per-month subscription is required for full features. The Ring 5 is recommended for first-time buyers or those upgrading from Ring 2 or 3, but Ring 4 owners may not see dramatic gains.
