As someone who has always been intrigued by the intersection of technology and personal health, I was eager to try out the Oura Ring 4. Living in Arizona, where the climate and lifestyle encourage an active and health-conscious routine, I found the idea of a discreet, ring-based health tracker particularly appealing. The promise of continuous health monitoring without the bulk of a traditional smartwatch was compelling.
After several months of daily use, I can confidently say that the Oura Ring 4 has significantly enhanced my understanding of my health patterns. From sleep quality to activity levels, the insights provided have been both enlightening and actionable. In this review, I'll share my personal experiences with the Oura Ring 4, discussing its design, functionality, and overall impact on my daily life.
Design and Comfort
The Oura Ring 4 boasts a sleek, minimalist design that seamlessly blends with both casual and formal attire. Its titanium construction ensures durability while maintaining a lightweight feel. One of the most notable improvements over previous versions is the recessed sensors, which eliminate the discomfort caused by protruding components. This design choice enhances comfort, making it easy to wear the ring 24/7 without irritation.
In my experience, the ring's comfort is unparalleled. Whether typing on a keyboard, lifting weights, or sleeping, I often forget I'm wearing it. The expanded size range, now accommodating sizes 4 through 15, ensures a snug fit for a variety of finger sizes. This thoughtful design makes the Oura Ring 4 not just a health tracker but also a stylish accessory.
Sleep Tracking and Insights

Sleep tracking is where the Oura Ring 4 truly shines. The device monitors various sleep stages, including REM, light, and deep sleep, providing a comprehensive overview of sleep quality. The accompanying app presents this data in an easy-to-understand format, offering insights into sleep duration, latency, and efficiency.
Personally, I've found the sleep insights invaluable. On nights when I consumed caffeine late in the day, the ring accurately reflected decreased sleep quality. Conversely, after evening walks, my sleep scores improved, reinforcing the benefits of light exercise before bed. These observations have helped me adjust my habits to promote better sleep.
Activity and Readiness Monitoring
The Oura Ring 4 tracks daily activity, including steps, calorie burn, and overall movement. It also provides a "Readiness Score," which assesses how prepared your body is for the day based on factors like sleep, activity, and heart rate variability. This feature has been particularly useful in managing my energy levels and planning workouts.
For example, on days when my readiness score was low, I opted for lighter activities like yoga or stretching. Conversely, higher scores encouraged me to engage in more intense workouts. This personalized feedback has helped prevent overexertion and promote recovery, aligning my physical activity with my body's needs.
App Experience and Features
The Oura app is intuitive and user-friendly, presenting data in a clear and organized manner. It offers various tabs for sleep, activity, readiness, and more, allowing for easy navigation. One feature I particularly appreciate is the ability to add tags to specific days, noting factors like stress, illness, or travel, which can influence health metrics.
Additionally, the app's "Explore" section provides guided meditations and breathing exercises, promoting mindfulness and stress reduction. These resources have been a valuable addition to my daily routine, offering moments of calm and focus amidst a busy schedule.
Battery Life and Charging

The Oura Ring 4 offers impressive battery life, lasting up to seven days on a single charge. In my experience, I typically charge the ring once a week, which is convenient and minimizes disruptions to data tracking. The charging process is straightforward, with the ring fully charging in under 90 minutes.
This extended battery life ensures continuous monitoring without the need for frequent recharging, a significant advantage over many wrist-based fitness trackers. It allows for uninterrupted data collection, providing a comprehensive view of health metrics over time.
