The Oura Ring 5, released in May 2026, introduces a thinner 6mm-wide, 2mm-thick design that is 40% smaller than its predecessor, the Oura Ring 4. Priced at $399, the device features improved sensor accuracy and expanded health tracking, including the ability to monitor GLP-1 response, while maintaining a subscription-based model for full data access.
Design and Hardware Refinements
The Oura Ring 5 represents a significant shift in form factor. According to CNET, the ring measures 6mm wide and 2mm thick, marking a 40% reduction in size compared to the Oura Ring 4. This structural change aims to improve comfort during physical activities, such as weightlifting. Beyond the physical footprint, the device includes more accurate sensors and enhanced workout detection capabilities. Despite the more compact chassis, Oura has managed to increase battery life, addressing a common pain point for wearable users.
Expanded Health Monitoring Capabilities
Oura has broadened its health-tracking suite to address both general wellness and specific medical indicators. The updated “Health Radar” is designed to flag early signs of blood pressure changes and breathing patterns that may indicate underlying health conditions. Most notably, the device now includes tracking for GLP-1 response, a feature that distinguishes it from previous generations. Like the Oura Ring 4, which tracked heart rate, sleep stages, stress levels, body temperature, and blood oxygen, the Ring 5 continues to rely on the Oura app for data presentation, as the device itself remains screen-free.
Market Positioning and Competition
The wearable market has become increasingly crowded, forcing Oura to adapt its strategy. While Oura previously held a dominant position, competitors such as Ultrahuman and Circular have gained traction, according to CNET. The competitive landscape also extends to wrist-worn devices, such as the Google Fitbit Air, which offers a similar holistic health tracking approach at a lower $100 entry point. The Oura Ring 5 is priced at $399—a $50 increase over the base model of the Oura Ring 4—reflecting the company’s push into more advanced hardware and deeper software integration to maintain its market lead.
