Overview
Oura on Wednesday unveiled the Ring 5, its fifth-generation smart ring, billing it as the world’s smallest smart ring and the company’s most significant redesign since the product category emerged as a mainstream alternative to the smartwatch. At 6.09mm wide and 2.28mm thick — down from 7.99mm and 2.88mm on the Ring 4 — the new device is 40 percent smaller than its predecessor, according to TechCrunch. Pre-orders opened the same day, with shipping scheduled to begin June 4.
Design and Hardware
The size reduction required a full teardown of the product’s internals. TechCrunch reports that Oura redesigned the mechanical, electrical, optical, battery, and sensing architectures simultaneously. The result is a ring that 9to5Mac describes as “thinner and lighter, with a smoother curvature,” and that MacRumors notes resembles “a traditional wedding band” more closely than earlier models.
The Ring 5 is made from non-allergenic titanium with an enhanced scratch-resistant coating, weighs as little as 2 grams, and carries a 100-meter water-resistance rating, according to Tech Advisor. The device is available in US sizes 6 through 13.
Despite the smaller footprint, Oura says it improved sensor performance. 9to5Mac reports the Ring 5 features a new signal architecture for better skin contact, more powerful LEDs for consistent readings, and twelve stronger signal pathways for accuracy across more finger types and skin tones. Battery life runs six to nine days — one day longer than the Ring 4’s five to eight days — per Tech Advisor.
A new optional Charging Case accessory, priced at $99, provides one month of battery via wireless charging, according to MacRumors.
Health Radar and New Software Features
The headline software addition is Health Radar, a proactive monitoring system that 9to5Mac describes as providing “continuous biometric monitoring” and surfacing patterns members should pay attention to before they become problems.
Health Radar launches with two initial capabilities. The first, Blood Pressure Signals, monitors nighttime blood pressure patterns to detect cardiovascular strain, according to 9to5Mac. The Next Web notes the feature detects cardiovascular strain patterns rather than providing direct blood pressure measurement, and alerts users to concerning trends. The second, Nighttime Breathing, provides a 30-day rolling view of sleep-related breathing disturbances, per MacRumors.
Health Radar is available to members in the United States, India, and the United Arab Emirates starting in June 2026, according to Tech Advisor. Health Records integration — which lets US members import lab results and blood biomarkers — is available in 43 states, per Tech Advisor.
Other new features include GLP-1 Insights, which tracks medication dosing, side effects, and weight changes for members on that class of drugs, and Live Activity Tracking for real-time workout metrics during running and cycling, as reported by MacRumors and IBTimes Australia. Oura is also partnering with Counsel Health to offer AI-enabled telehealth services in 43 US states, according to IBTimes Australia.
The new software features are also rolling out automatically to existing Ring 3 and Ring 4 owners, per IBTimes Australia.
Pricing and Availability
The Oura Ring 5 starts at $399 for Silver and Black finishes, and $499 for premium finishes — Gold, Stealth, Brushed Silver, and Deep Rose. An Oura Membership is required for full functionality and costs $5.99 per month or $69.99 per year, according to 9to5Mac. The Ring 4 (Ceramic) remains available at $349, per MacRumors.
CEO Tom Hale described the product in a statement as a “real technological miracle,” adding that the goal was broader access: “By reimagining Oura Ring 5 to be smaller, easier to wear, and pairing it with our most advanced software yet, we’re making it possible for many more people to wear Oura every day,” according to IBTimes Australia.
What We Don’t Know
The company has not disclosed detailed clinical validation data for the Blood Pressure Signals feature, which — as The Next Web notes — detects cardiovascular strain patterns rather than measuring blood pressure directly in the way an FDA-cleared cuff would. The scope of the Counsel Health partnership and its pricing beyond the base subscription have not been publicly detailed.
Oura’s competitive position is sharpening at a moment when the smart ring category has grown crowded. The Next Web notes that Samsung’s Galaxy Ring matches Oura’s $399 entry price and weighs 2.3 grams minimum, while Apple’s entry into the category remains a persistent rumor without a confirmed timeline. As previously reported, even the sub-$100 end of the smart ring market has grown more active, with minimalist devices targeting different use cases than Oura’s full health-monitoring approach.
