Oura Ring 5 debuts with 40% smaller design and advanced health tracking

Oura has released the Oura Ring 5, a smaller and more advanced version of its popular health-tracking device. The new model builds on the company’s reputation for discreet, AI-powered wearable technology. It continues to offer detailed health insights through a lightweight, screenless design. The Oura Ring 5 launched in 2026 with a 40% reduction in size compared to its predecessor. It features a longer battery life and works with more healthcare apps. However, the upgraded model comes at a higher price.

The ring tracks over 50 health metrics, including heart rate variability, blood oxygen levels, body temperature, and active calories. It uses advanced sensors such as red, green, and infrared LEDs, a temperature sensor, and a 3D accelerometer to collect data. Specialised algorithms then analyse this information to provide personalised insights on sleep stages, ovulation cycles, and other health factors.

Oura’s AI assistant, Oura Advisor, offers data visualisations and scientifically backed advice for a monthly fee. The device integrates with hundreds of health apps and supports tracking for heart health, sleep quality, activity, stress, and women’s health. Users have praised its sleek titanium design and seamless app connectivity.

Despite its benefits, health-tracking wearables like the Oura Ring carry risks. These include potential data breaches and negative mental health effects from excessive monitoring. The Oura Ring 5 improves on earlier versions with better functionality and design. It provides extensive health tracking but also introduces concerns about data security and user well-being. The device remains a popular choice for those seeking detailed, personalised health insights.
