The Oura Ring 4 is highly regarded as a premium smart ring with significant improvements over its predecessors and competitors in the smart ring market. It is praised for its comfortable, elegant, and discreet design, highly accurate sleep and health tracking, and wellness-focused features that provide valuable insights for users focused on recovery, readiness, and overall wellness. Its new Smart Sensing technology improves sensor accuracy by optimizing data collection based on different factors like skin tone and finger shape, delivering fewer gaps and more reliable readings in heart rate, blood oxygen, and stress monitoring. The accompanying app is redesigned for better user experience and introduces features such as long-term stress management and personalized AI-powered health insights. Notable pros include a lightweight titanium build, water resistance up to 100 meters, long battery life (up to 8 days), and a streamlined app interface. The ring is suitable for wearing throughout the day and night, even during some water activities, though it is recommended to remove it for activities like weightlifting. However, it requires a subscription to unlock full data insights, lacks built- in GPS and extensive physical activity tracking, and does not come with a portable travel charging case. Compared to Oura Ring Gen 3, the Ring 4 features a smoother design, smaller sensor bumps, more signal pathways for better data accuracy, and longer battery life, though the size and thickness remain similar. In summary, the Oura Ring 4 is considered the best smart ring available today for those serious about health and wellness monitoring. It is less focused on exercise metrics and more on holistic health, sleep optimization, and recovery. The cost is premium, with the ring starting at $349 and an additional subscription fee ($5.99/month or $69.99/year), but many reviewers find the investment worthwhile due to the depth of insights and comfort it provides.
