Oura released its fifth-generation smart ring, marking the company's smallest device yet. The Oura Ring 5 maintains the brand's core tracking capabilities while reducing physical size, a move aimed at expanding appeal among users who found earlier versions too bulky.
The ring tracks sleep, heart rate variability, and body temperature through sensors embedded in the titanium band. These metrics feed into Oura's algorithm, which generates a daily readiness score and sleep stage breakdown. The company claims the smaller form factor doesn't compromise sensor accuracy or battery performance.
Oura Ring 5 users access data through the companion app, which displays sleep duration, REM and deep sleep percentages, and recovery metrics. The ring's algorithm learned from anonymized data collected across previous generations, refining how it interprets physiological signals. Battery life remains around five to seven days between charges, consistent with earlier models.
The device requires a subscription to Oura's membership program for full feature access. Without it, users see only basic metrics. The subscription tier unlocks detailed sleep coaching, personalized readiness recommendations, and historical trend analysis.
Compared to fitness watches, the Oura Ring 5 trades screen display for wearability. Users cannot check metrics on the device itself. The ring's advantage lies in 24/7 wear without the bulk of a wristband, making continuous biometric tracking simpler for people who sleep with watches on their wrists or prefer minimal visible technology.
The smaller size addresses a common complaint from previous Oura Ring owners. Sizing options expand to accommodate narrower fingers. The ring uses the same charging dock as earlier generations, maintaining compatibility with existing accessories.
Oura Ring 5 comes in several finishes and costs the same as Ring Gen 3. The company positioned this update as an engineering refinement rather than a feature overhaul, focusing on accessibility and
