A CNET review highlights the Oura Ring as the best smart ring for monitoring fitness, sleep, and stress in 2026, outperforming competitors after months of testing. The Ultrahuman Ring Air, previously favored for workouts, faces a US ban due to an Oura lawsuit. The Evie Ring targets menstrual health but falls short on actionable insights.
CNET's fitness expert tested three smart rings over several months to evaluate their effectiveness for health and fitness goals in 2026. The Oura Ring, priced at $349 plus a $6 monthly subscription, emerged as the top choice for its user-friendly app and comprehensive tracking. Made of aerospace-grade titanium, it monitors sleep, readiness scores out of 100, heart rate, stress levels, and cycle insights for menstruating users. The device auto-tracks movement, detects potential illness onset, and suggests bedtime windows based on chronotype, aiming for optimal rest like 8 hours if waking at 6 a.m.
Key features include a rechargeable battery lasting about three days and water resistance for daily use. Recent updates with the Oura Ring 4 introduce AI for advanced habit analysis, cardiovascular age estimation, and chronotype detection. The reviewer noted improved energy after following sleep recommendations, even amid stressors like moving. Oura's holistic approach avoids guilt, instead offering personalized advice via its Oura Advisor for recovery and lifestyle tweaks. Integrations with apps like Apple Health and Strava enhance usability, though more connections, such as with baby monitors, could appeal to new parents.
Drawbacks include vulnerability to scratches during workouts, limited real-time fitness logging beyond cardio activities, and the subscription cost. The Ultrahuman Ring Air, also $349 with no subscription, excels in workout variety but was banned in the US following Oura's lawsuit; it remains usable for owners and tracks sleep, recovery, and caffeine windows using PPG sensors. However, its app feels cluttered, and metrics like running pace proved inaccurate compared to an Apple Watch. The Evie Ring, at $269 without fees, focuses on menstrual cycles, sleep, and activity but lacks personalized recommendations, functioning more as a diary despite an AI chatbot update.
Overall, the Oura Ring provides the most reliable, insightful data for broad health overviews, while competitors show potential with refinements.
