"Our reviews are based on actual hands-on testing and data metrics in our US labs. We prioritize long-term durability and real-world performance."

The Oura Ring 4 represents a significant leap forward in the world of smart rings. Engineered with premium titanium, this fourth-generation wearable moves away from the internal sensor bumps of its predecessor, opting for a smooth, recessed interior that provides unparalleled 24/7 comfort. Whether you are tracking your REM sleep, monitoring your heart rate, or keeping an eye on your daily stress levels, the Oura Ring 4 delivers data with clinical-grade precision.

At the heart of the Oura Ring 4 is the new Smart Sensing technology. This system utilizes 18 signal pathways (compared to 8 in the previous model) to adapt to your finger's unique structure and skin tone, ensuring consistent accuracy even if the ring rotates during the night. With up to 8 days of battery life and 100-meter water resistance, it is a robust companion for anyone looking to optimize their longevity and performance without the bulk of a traditional smartwatch.

While the hardware is world-class, the Oura App provides the actionable insights that make the data meaningful. From personalized Readiness Scores to menstrual cycle tracking and activity detection, the ecosystem is designed to help you listen to your body. Note that a monthly subscription is required to unlock the full suite of health metrics, making this a premium investment for serious health enthusiasts.
