The Oura Ring 4 is a sleek, fully titanium smart ring designed to deliver accurate 24/7 health tracking without the bulk or distractions of a smartwatch.

Featuring breakthrough Smart Sensing technology with 18 sensing paths and recessed sensors for all-day comfort, it monitors over 50 wellness metrics including sleep quality, heart rate variability, stress levels, blood oxygen, body temperature, activity, and women's health.

With an all-titanium construction inside and out, the Ring 4 is lighter, smoother, and more accurate than previous generations, providing up to 8 days of battery life on a single charge.

Available in six refined finishes—Black, Silver, Stealth, Brushed Silver, Gold, and Rose Gold—and sizes 4-15, it seamlessly integrates with the Oura app to deliver personalized daily readiness scores, activity goals, and AI-powered insights that help you understand your body's needs and build healthier habits.
