Oura Ring 5 Review: Smaller, Smarter, More Accurate! (2026)

Oura's latest innovation, the Oura Ring 5, is set to revolutionize the wearable tech industry, particularly in Australia, New Zealand, and Singapore. This sleek and smaller iteration of the Oura Ring is a significant leap forward in smart ring technology, offering a host of exciting features and improvements.

A Smaller, More Wearable Design

The Oura Ring 5 is a masterpiece of engineering, boasting a 40% reduction in size compared to its predecessor. This achievement required a complete rethink of the ring's mechanical, electrical, optical, battery, and sensing architecture. The result is a device that is not only smaller but also easier to wear throughout the day, ensuring accurate measurements without compromising on comfort.

Holly Shelton, Chief Product Officer at Oura, emphasizes the challenge of achieving this size reduction while maintaining accuracy: "To make something 40 percent smaller without sacrificing an ounce of accuracy, we had to rethink every assumption - the sensors, the battery, the architecture, the geometry of the ring itself."

The design changes include lower-profile sensor domes, stronger LEDs, and 12 signal pathways, ensuring precise readings across various finger types and skin tones. The ring also features a tough physical vapor deposition coating for scratch resistance and is rated dust-resistant and waterproof to 100 meters under IP68 standards.

Enhanced Software Features

Oura has also introduced a range of software updates to complement the hardware improvements. One of the standout features is Live Activity Tracking, which allows users to start a workout in the Oura app and follow pace and distance on their phone, with support for connected heart rate monitors.

The device-finding tool, Locate, is another valuable addition, supporting multiple devices and offering an in-app search mode for rings and charging cases. Additionally, a time-based data deletion tool enables users to remove app data from a selected period while preserving their account history.

Women's Health Focus

Oura has made significant strides in women's health with the introduction of Menopause Insights and Cycle Insights. Menopause Insights includes a comprehensive questionnaire, the Menopause Impact Scale, which assesses various aspects of daily life affected by menopause. The results are presented in a user-friendly dashboard within the app.

Cycle Insights, on the other hand, is tailored for users of hormonal birth control. It provides valuable insights into how biometrics shift over time, distinguishing between hormone-taking and hormone-free days.

Global Expansion and Accessibility

Oura's global reach is expanding, with the Oura Ring 5 now available in Australia, New Zealand, and Singapore. The company's website and select retailers, including JB Hi-Fi, Harvey Norman, Amazon, and Noel Leeming, will offer the ring for purchase. Oura advises buyers to use the new sizing kit, as the smaller shape may affect fit even for those with previous generation rings.

The charging case, sold separately, is designed to provide up to a month of battery charge and supports wireless charging. Users can effortlessly pair and switch between Oura Ring 4 and Oura Ring 5 devices on a single account.

Conclusion: A Step Towards Personalized Health

Tom Hale, CEO of Oura, encapsulates the company's vision: "Oura Ring 5 is a big step toward our vision of giving every body a voice. 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 and benefit from personalized, predictive health insights."

The Oura Ring 5 is a testament to Oura's commitment to innovation and its mission to empower individuals with personalized health insights. With its smaller design, advanced software, and focus on women's health, this wearable device is poised to become a game-changer in the health and wellness industry.
