Published: January 11th, 2026

Pros

  • Provides detailed and accurate insights into sleep quality, including REM sleep and overall sleep scoring.
  • Offers personalized recommendations for workouts and rest based on energy and recovery levels.
  • Tracks vital signs such as daytime heart rate, sleep heart rate, and streselated heart rate changes with real-time and historical data.
  • Comfortable and stylish alitanium design that fits well for work, workouts, and sleep without feeling bulky.
  • Waterproof, allowing continuous wear during everyday activities like showering and swimming.
  • Battery life lasts up to 8 days, with quick charging—10 to 15 minutes of charge can power it for several days.
  • The Oura Ring 4 Sizing Kit is very accurate and essential for finding the perfect fit.
  • Minimalist design makes it a discreet wearable that doesn’t add to screen time but still tracks extensive health metrics.
  • Subscribing to the app improves setup experience and provides comprehensive health analysis.
  • Responsive customer service that quickly assists with issues like battery problems.

Cons

  • Fitness tracking for calories burned and steps may not be very accurate, so it’s not ideal if those metrics are your top priority.
  • Some users experienced skin irritation when wearing the ring continuously for 24 hours.
  • Nighttime light sensors can bother sensitive sleepers, though this can be managed by covering the hand.
  • The ring can feel relatively thick, which might be intrusive for certain activities like weightlifting.
  • The product’s sizing and fit are notandard, making the sizing kit a must-have prior to purchase.
  • The price is relatively high, and there can be notable price differences between sellers.
  • Delivery restrictions exist for some locations (e.g., certain Amazon SG areas).
  • Limited direct product comparisons due to few similar smart ring options on the market.

Bottom Line

The Oura Ring 4 is an excellent choice for those who want a sleek, comfortable, and comprehensive health tracker focused mostly on sleep, recovery, and stress management rather than pure fitness metrics like step counting or calorie burn. Its long battery life, waterproof design, and personalized insights make it a top-tier smart ring that quickly becomes an indispensable daily wellness tool—*just be sure to size carefully with the included kit before committing*. If step and calorie tracking are your main goals, you might want to consider a dedicated fitness tracker instead, but for health and well-being as a whole, the Oura Ring 4 is a solid investment.
