Oura Ring 5
Health Monitoring, Sleep Tracking, Fitness Tracking, Heart Health, Women's Health, Stress Management, Recovery Tracking, Illness Detection, 24/7 Wellness Monitoring
Overview
The Oura Ring 5, announced May 28, 2026, is the world's smallest smart ring, re-engineered to be 40% smaller than its predecessor while improving accuracy and battery life. It packs a redesigned 12-signal-pathway sensor array — tri-LED PPG, temperature sensor, and accelerometer — into a 6.09mm-wide titanium band that tracks 50+ health metrics including sleep stages, heart rate, HRV, SpO2, temperature trends, stress, and women's health. Available in six finishes at $399–$499, the Ring 5 pairs with new software experiences like Health Radar and AI medical guidance, though most insights require an Oura Membership subscription.
Key Highlights
- World's smallest smart ring — 40% smaller than the Oura Ring 4 with a fully titanium design (6.09mm wide, 2.28mm thick, from 2g) in six finishes: Gold, Deep Rose, Brushed Silver, Stealth, Black, Silver
- Waterproof to 100m/328ft (IP68) with super-hard PVD coating for scratch resistance and a non-allergenic, BPA-free titanium inner shell
