Oura has announced a new version of its popular smart ring, called the Oura Ring 5. Compared to the Ring 4, the new model has a 40% smaller body (2.28mm thick), made of lightweight, non-allergenic titanium.

To achieve a thinner and lighter design, the brand has reworked the mechanical, electrical, optical, battery, and sensing architecture.

Oura Ring 5 has a smaller design and upgraded sensors

The Ring 5 uses low-profile sensor domes, stronger LEDs, and 12 signal pathways to get cleaner and more consistent readings from the finger across different skin tones. Its battery life has been increased to last between six and nine days.

It is available in sizes ranging from 6 to 13 and comes in Silver, Black, Gold, Stealth, Brushed Silver, and Deep Rose. Oura says this is its most scratch-resistant ring so far because of a stronger physical vapor deposition coating. It also has an IP68 rating and is waterproof to 100 meters.

The company is also launching a $99 aluminum charging case for the Ring 5, which can store one month of battery, supports wireless charging, and has an action button for checking charging status and pairing.

Oura is adding more health features to the app

Health Radar is the biggest update that has been launched for Oura subscription members with Gen 3 rings and above. It has two main capabilities called Blood Pressure Signals and Nighttime Breathing. The Blood Pressure Signals feature monitors blood pressure during sleep, when factors such as movement, stress, and caffeine are not affecting readings as much. It can alert users if it detects unusual cardiovascular strain during sleep.

Users can also log readings from a traditional blood pressure cuff directly in the Oura app, so those measurements can sit alongside their longer-term Oura trends.

Nighttime Breathing also works in a similar way by tracking breathing during sleep and giving users a 30-day view of sleep-related breathing disturbances. This makes it easier to spot patterns that may need medical attention.

Other new software features include Live Activity Tracking, which turns the Oura app into a more active workout companion. Users can start a workout from the app and see pace, distance, and connected heart rate in real time. The feature supports running, cycling, and strength training, and can also pull heart rate data from third-party monitors and supported devices.

Oura Ring 5 is available for preorder now and starts shipping on June 4, 2026. It costs $399 in Silver and Black, and $499 in Gold, Stealth, Brushed Silver, and Deep Rose.
