Hardware & Design Redesign
The "World's Smallest Smart Ring":The headline feature is its size—the Oura Ring 5 is 40% smaller and lighter in volume than the Oura Ring 4.It has been narrowed down to a width of 6.09mm and a thickness of just 2.28mm,allowing it to feel much more like traditional,non-tech jewelry.

Upgraded Sensing Architecture:Despite its smaller size,Oura re-engineered the internal sensors.It rotates and repositions the LEDs closer to the skin with a "flat-top" dome design.It features 12 optimized signal pathways paired with LEDs that are four times more powerful,delivering cleaner,more accurate readings across various finger sizes and skin tones (including a 24% improvement in signal quality for workout heart rates).

Enhanced Scratch Resistance:Built with a high-grade titanium frame,it features an upgraded physical vapor deposition (PVD) coating process that drastically improves everyday scratch resistance.It is also waterproof up to 100 meters (328 feet).

Advanced Health & Software Enhancements
Health Radar (Proactive Monitoring):Building on the previous "Symptom Radar," this feature uses background monitoring to track long-term cardiovascular and metabolic shifts while you sleep. It includes Blood Pressure Signals(to track cardiovascular strain overnight without needing a blood pressure cuff calibration) and Night time Breathing Analysis (offering a rolling 30-day view of respiratory disturbances).

Live Activity Tracking: For the first time,users can start a workout in the Oura app and view real-time metrics like heart rate,pace,and distance on their phone’s screen or lock screen widgets (utilizing the phone's GPS).Automatic activity tracking has also been fine-tuned to catch low-motion workouts like Pilates.

Women's Health Expansions:The Ring 5 introduces a Hormonal Birth Control feature that adjusts cycle insights for those using pills, IUDs,or implants to see how contraception alters bodily baselines.It also introduces Menopause Insights,featuring a research-driven clinical questionnaire to monitor how symptoms impact sleep,mood,and daily biometrics.

Connected Care & Counsel Health Partnership:Oura integrated an online medical service directly into the app.Through a partnership with Counsel Health,users can get AI-enabled medical advice or seamlessly jump into a live chat with a licensed,real-world physician (available in 43 US states for an additional fee).

Lab Uploads & Oura Health Records:Users can now import external blood work biomarkers,lab results,and diagnosed clinical histories directly into the app,placing traditional medical records alongside daily wearable metrics for a holistic health view.

GLP-1 Medication Insights:For users taking GLP-1 weight-loss medications,the app now provides a longitudinal tracking view to log dosages,manage side effects,and map how the medication influences sleep and overall readiness.
