Oura Launches Sleeker Ring 5 Smart Ring With Lighter Build Starting at $399

Oura on Thursday introduced the fifth generation of its smart ring lineup, the Ring 5, with pricing beginning at $399. The company describes the new device as the smallest smart ring available today, arriving just a year and a half after Ring 4's launch and several months after the Ring 4 Ceramic edition. According to Oura, the Ring 5 is around 40% smaller than the previous model while offering improved sensor accuracy and longer battery life.

Alongside the new hardware, Oura is also rolling out a range of software enhancements, including blood pressure insights, live activity tracking, on-demand healthcare services, and additional wellness features. These updates will also be available to users of the Oura Ring Gen3 and newer devices.

Preorders for the Ring 5 open today, with shipments scheduled to begin on June 4. The ring is available in sizes 6 through 13 and comes in six finishes: Silver, Brushed Silver, Black, Stealth, an updated Gold, and a redesigned Deep Rose. The Black and Silver versions are priced at $399, while the remaining finishes cost $499. By comparison, the Ring 4 launched at a starting price of $349.

Maz Brumand, Oura's Vice President of Product, said the company reduced the ring's width by approximately two millimetres and its thickness by nearly 30%. He explained that customer feedback consistently pointed to a desire for a slimmer, lighter design. To achieve this, Oura redesigned multiple internal components, including the battery, sensors, optical systems, electronics, and mechanical architecture.

The company believes the smaller design will appeal to consumers who previously found smart rings too bulky. Oura says the Ring 5 is intended to feel and look more like a traditional ring while maintaining advanced health-tracking capabilities.

Competition in the smart ring market has intensified in recent years, with rivals such as RingConn and Ultrahuman introducing subscription-free alternatives. That competitive pressure may help explain Oura's faster product cycle, given the shorter gap between Ring 4 and Ring 5 compared with the roughly three-year period between Ring 3 and Ring 4. The announcement also comes just before RingConn begins shipping its Gen 3 smart ring.

Battery performance has also improved. Oura says Ring 5 can operate for six to nine days on a single charge, compared with five to eight days for Ring 4.

In addition, the company has redesigned its sensor system to improve skin contact and incorporated more powerful LEDs. Oura says these upgrades enhance accuracy across a wider variety of skin tones and finger sizes.

Software Updates

The software updates accompanying Ring 5 are centred around a new feature called Health Radar, which continuously monitors biometric data in the background to identify important health patterns. The platform launches with two key features: Blood Pressure Signals and Nighttime Breathing.

According to Oura, Blood Pressure Signals can identify patterns that may indicate increased cardiovascular strain. The system focuses on overnight measurements, when blood pressure patterns are generally more stable and naturally lower. If blood pressure does not decline as expected during sleep, it may suggest potential cardiovascular concerns that daytime readings could overlook. Users will also be able to manually log blood pressure readings from external monitoring devices within the app.

Nighttime Breathing provides users with a broader view of how breathing patterns during sleep may influence overall health. Members will receive a rolling 30-day overview of sleep-related breathing disturbances and trends, expanding on the breathing insights already available through the platform.

Oura is also entering the healthcare services space through a partnership with Counsel Health, a platform that combines AI technology with licensed physicians. Through the integration, users will be able to ask health-related questions, receive personalized guidance, and connect directly with doctors in the United States. This service will require an additional fee on top of Oura's standard $5.99 monthly membership, although pricing has not yet been disclosed.

For U.S. users, the company is also introducing the ability to import diagnosed medical conditions, medications, allergies, and laboratory results into the Oura app. Oura says it is implementing a privacy-focused approach for handling this sensitive health information.

The company is also enhancing fitness tracking with a new live activity experience. Users can now begin workouts and view real-time performance metrics, including pace and distance, directly from their phones during activities such as running and cycling. Oura has also improved its Automatic Activity Detection system to recognize lower-motion exercises, such as Pilates better. In addition, users can connect external heart rate monitors for live heart rate tracking.

Another new feature provides GLP-1 medication insights, giving members a long-term view of their treatment journey while tracking changes in weight and body composition over time.

Oura is also expanding into brain health research. Eligible members will be invited to participate in a Brain Health Study that combines short in-app cognitive exercises with long-term physiological data. The company hopes the research will help identify connections between daily habits, recovery patterns, mental sharpness, and long-term cognitive health.

With the launch of Ring 5 and a growing range of health-focused software tools, Oura continues to broaden its ambitions beyond fitness tracking, positioning its platform as a more comprehensive health and wellness ecosystem.
