Oura has unveiled the Oura Ring 5, the latest generation of its finger-based wearable, introducing a range of new health-tracking capabilities while significantly reducing the device’s size.

The launch comes more than a decade after the first Oura Ring reached the market, marking the fifth iteration of the company’s smart ring lineup. Alongside new software and health-monitoring tools, Oura has placed considerable emphasis on the ring’s physical redesign, saying the Oura Ring 5 is 40% smaller than the previous-generation Ring 4.

The company describes the device as the smallest smart ring currently available. The reduction in size appears aimed at making the wearable even less noticeable during daily use, an area that has become increasingly important as smart rings compete on comfort as much as functionality.

Health monitoring remains central to the new device. One of the headline additions is Health Radar, a system that introduces two primary measurements: Blood Pressure Signals and Nighttime Breathing.

According to Oura, Blood Pressure Signals can monitor changes in blood pressure and alert users to increasing levels. The feature is also designed to track blood pressure during sleep. Nighttime Breathing, meanwhile, provides a rolling 30-day view of breathing patterns and disturbances recorded overnight, giving users a longer-term picture of their sleep-related respiratory trends.

The rollout of Health Radar will be limited initially. Oura said both Health Radar and GLP-1 Insights, a metabolic health-tracking feature intended for users taking GLP-1 medications, will become available beginning in June 2026 for Oura Ring Gen3 and newer devices in the United States, the United Arab Emirates and India.

While Oura’s products have traditionally focused more heavily on sleep, recovery and wellness metrics than athletic performance, the company has expanded its activity features with the new ring. The Oura Ring 5 adds live activity tracking for workouts including running, cycling and strength training.

Another addition is a data deletion tool that allows users to remove information collected during a selected period. The feature gives users more control over the health and activity data stored within the platform.

Battery performance remains a key part of the device’s appeal. Oura said the ring itself can operate for up to a week on a single charge, while the accompanying charging case can extend total usage to roughly one month before requiring a recharge.

Most of the experience continues to be delivered through the Oura mobile application, where users can view and manage the information collected by the ring. However, several advanced functions remain tied to Oura’s subscription service.

Features including detailed sleep analysis, blood oxygen sensing and metabolic health tracking require a subscription priced at US$5.99 per month or US$69.99 annually. Users who do not subscribe can still access their Readiness, Sleep and Activity scores through the app.
