Key Features
Sleep Tracking
Wake up to a detailed analysis of your sleep. The Oura Ring 4 sleep tracker monitors your Deep, REM, and Light sleep stages, along with your nightly heart rate variability (HRV) and temperature trends. This best Oura Ring model provides the most accurate sleep tracking available.
The Oura Ring uses advanced sensors to monitor your sleep architecture throughout the night. It provides insights into your sleep latency (how quickly you fall asleep), sleep efficiency, total sleep time, and restfulness. The ring tracks your body temperature variations, which can indicate sleep quality and help identify potential illness or stress. With HRV monitoring, you get a comprehensive view of your recovery status each morning.
Readiness Score
Know exactly when to push your limits and when to rest. The Readiness Score combines your sleep, activity, and body stress signals to give you a daily capacity rating.
The Readiness Score is Oura's signature metric, calculated from three key contributors: sleep quality, activity balance, and previous day's activity. This score ranges from 0-100 and helps you understand whether you should train hard, take it easy, or focus on recovery. A high readiness score suggests your body is ready for intense activity, while a lower score indicates you might benefit from rest or lighter exercise.
Activity Monitoring
Track your daily movement, calories burned, and steps with the Oura smart ring. This health tracker automatically detects workouts and encourages you to stay active with personalized goals. The Oura Ring 4 offers comprehensive activity tracking.
Beyond basic step counting, Oura Ring monitors your active calories, total calories, and metabolic equivalent of task (MET) hours. The ring automatically detects when you're exercising and can track over 50 different activity types. It provides real-time heart rate monitoring during workouts and calculates your training load to help prevent overtraining and optimize performance.
Advanced Health Metrics
Heart Rate Variability (HRV)
HRV is one of the most important biomarkers for overall health and recovery. The Oura Ring measures your HRV during sleep, providing insights into your autonomic nervous system balance. Higher HRV typically indicates better recovery and stress resilience, while lower HRV may suggest overtraining, illness, or high stress levels. Oura tracks your HRV trends over time, helping you understand how lifestyle factors affect your recovery.
Body Temperature
The Oura Ring continuously monitors your body temperature, detecting even subtle changes that can indicate illness, stress, or hormonal fluctuations. The ring tracks your baseline temperature and alerts you to significant deviations. This feature has proven particularly valuable for women tracking their menstrual cycles, as temperature changes can indicate ovulation and other cycle phases.
Respiratory Rate
Your breathing rate during sleep is another key indicator of recovery and health. Oura tracks your respiratory rate throughout the night, providing insights into your overall health status. Changes in respiratory rate can indicate stress, illness, or changes in fitness level. The ring provides both average and range metrics to help you understand your breathing patterns.
Blood Oxygen Levels (SpO2)
The Oura Ring 4 includes SpO2 monitoring, which measures the oxygen saturation in your blood during sleep. This metric can help identify sleep apnea, breathing issues, or altitude-related changes. The ring provides nightly SpO2 averages and can detect significant drops that may require medical attention.
Activity Score
Beyond simple step counting, Oura's Activity Score considers your movement intensity, duration, and recovery needs. The score helps you balance activity with rest, preventing overtraining while encouraging consistent movement. It provides personalized activity goals based on your readiness and recovery status.
Sleep Score Breakdown
Your nightly Sleep Score is calculated from multiple factors: total sleep time, efficiency, restfulness, REM sleep, deep sleep, and latency. Each component is scored individually, helping you understand which aspects of your sleep need improvement. The detailed breakdown makes it easy to identify patterns and make targeted lifestyle changes.
Oura Ring 4 Specifications
Sensors and Technology
The Oura Ring 4, the latest Oura smart ring model, features an impressive array of sensors packed into its compact design. This best Oura Ring includes infrared photoplethysmography (PPG) sensors for heart rate monitoring, a negative temperature coefficient (NTC) sensor for body temperature tracking, a 3D accelerometer and gyroscope for movement detection, and an SpO2 sensor for blood oxygen monitoring. The Oura Ring health tracker provides medical-grade accuracy.
The ring uses advanced algorithms to process data from these sensors, providing accurate health metrics without the bulk of traditional wearables. The sensors are positioned on the inner surface of the ring, making direct contact with your finger for optimal data collection. This placement allows the ring to measure data directly from your arteries, providing more accurate readings than wrist-based devices.
Design and Materials
Oura Ring 4 is available in multiple finishes including Titanium, Black, Stealth, Silver, and Gold. The ring is water-resistant up to 100 meters, making it suitable for swimming and water activities. The titanium construction ensures durability while maintaining a lightweight feel. The ring comes in multiple sizes (6-13) to ensure a perfect fit, which is crucial for accurate sensor readings.
How Oura Ring Works
Continuous Monitoring
Unlike devices that only track during specific activities, Oura Ring monitors your body continuously throughout the day and night. The ring collects data every minute, building a comprehensive picture of your health patterns. This continuous monitoring allows Oura to detect subtle changes that might be missed by intermittent measurements.
Data Processing
The Oura app uses sophisticated algorithms to process the raw sensor data into meaningful insights. The app analyzes patterns over time, comparing your current metrics to your personal baseline. This personalized approach means the insights become more accurate as you wear the ring longer, typically improving after 1-2 weeks of consistent use.
Actionable Insights
Oura doesn't just present data—it provides actionable insights and recommendations. The app suggests optimal bedtimes, activity levels, and recovery strategies based on your personal data. These recommendations are tailored to your unique physiology and lifestyle, making them more effective than generic health advice.

The HRV and readiness scores are particularly valuable for preventing overtraining and reducing injury risk. Many professional athletes use Oura to fine-tune their training and recovery protocols.
Sleep Optimization Seekers
If you're struggling with sleep quality or want to optimize your sleep patterns, Oura Ring provides detailed insights into what's affecting your rest. The ring tracks how factors like alcohol, late meals, exercise timing, and stress impact your sleep quality. This data helps you make informed decisions about your evening routines and sleep hygiene.
Health-Conscious Individuals

The ring can help detect early signs of illness through temperature and HRV changes, making it a valuable tool for proactive health management. It's particularly useful for tracking how lifestyle changes affect your overall well-being.
Women's Health Tracking
Oura Ring has become popular among women for cycle tracking and reproductive health. The temperature monitoring feature can help identify ovulation and other cycle phases. The ring's ability to track how hormonal changes affect sleep, recovery, and activity makes it a valuable tool for understanding menstrual cycle impacts on overall health.
