In a market saturated with fitness trackers and smartwatches, the Oura Ring 4 distinguishes itself through its sleek, minimalist design and a focus on providing science-backed wellness insights. This article delves into the features of the Oura Ring 4, exploring its capabilities in sleep tracking, stress monitoring, and activity analysis, and examining its potential benefits for weight management.
Introduction
If you're seeking an alternative to bulky fitness trackers that require constant charging and have bright screens, the Oura Ring 4 is worth considering. The latest generation of this popular smart ring offers upgraded sensors, real-time stress tracking, and in-depth recovery insights. This review explores its sleep tracking, stress monitoring, sport modes, and other details gathered over six months of testing.
Oura Ring 4: Key Features and Functionality
The Oura Ring 4 collects health data through recessed sensors within its titanium band. These sensors measure body temperature, blood oxygen levels, and heart rate with greater accuracy due to the stable blood flow on the finger. The Oura Ring 4 provides daily scores based on around-the-clock tracking:
- Sleep Score: Reflects sleep quality based on REM, deep sleep, restfulness, and total time asleep.
- Readiness Score: Indicates how prepared the body is for activity, using HRV, resting heart rate, and sleep quality.
- Activity Score: Summarizes daily movement patterns, including duration, intensity, and recovery time.
- Stress Monitor: Shows when the body is calm, active, or under strain throughout the day and can predict potential illness.
These metrics are accessible on the Oura app, which provides clear charts, personalized details, and recommendations.
Accuracy of Health and Fitness Tracking
Sleep Tracking
The Oura Ring 4 accurately tracks sleep cycles, including REM sleep, light sleep, deep sleep, latency, restfulness, and resting heart rate. It accurately reflects poor sleep with a low sleep score and provides warnings to take it easy the next day. The ring can also detect the effects of alcohol consumption on sleep, noting a higher resting heart rate and restless sleep.

Recovery Tracking
The recovery tracking feature is typically accurate, comparing activity to rest and HRV to determine readiness for the day. The score indicates whether the body is ready for activity or needs more rest.
Fitness Tracking
While the Oura Ring tracks up to 40 different kinds of workouts, the accuracy isn’t always there. When comparing calories burned with an Apple Watch, the Oura Ring consistently lists around half the calories burned. This discrepancy may be due to rapid heart rate fluctuations not fully detected during exercise. Manual logging is possible, but the Oura Ring lacks the seamless start/stop controls of a smartwatch.
Stress Tracking
The stress feature is a significant strength of the Oura Ring. It identifies periods of high stress, reflected in an elevated resting heart rate and lower HRV. The ring can also detect stress affecting the body before the onset of illness, using heart rate and basal body temperature. Stress levels affect the readiness score, which is typically lower after a stressful day.
Comparisons with Other Fitness Trackers
The Oura Ring 4 stands out as a wellness-focused tracker, outperforming the Apple Watch Ultra 2 in sleep tracking and readiness insights. However, the Apple Watch excels in real-time performance metrics and smartwatch features. Compared to the Garmin Instinct 3, the Oura Ring is less effective for in-the-moment performance metrics. It is designed for understanding health and recovery without obsessing over every stat mid-workout.
Compared to Whoop 4.0, Oura is slightly less focused on athletes and more accessible to general wellness users. Whoop offers robust workout strain analysis and coaching tools, while Oura offers a more lifestyle-oriented lens, focusing on sleep and readiness for stress.

Oura Ring 4 vs. Oura Ring Gen3
The main differences between the Oura Ring 4 and its predecessor are real-time stress tracking, continuous heart rate monitoring, and more accurate temperature sensing. These updates provide more nuanced and responsive feedback throughout the day. The Oura Ring 4 also ditched the three sensor nodes found on the Gen3, resulting in a lighter and more comfortable design.
Using the Oura Ring 4 for Fitness and Health Tracking
Fitness Tracking Experience
The Oura Ring accurately logged yoga and strength training sessions compared to Apple Watch metrics, but high-intensity work was off in accuracy. It is an excellent recovery companion, indicating when to push harder and when to back off.
Health Tracking Experience
The Oura Ring flagged elevated body temperature, disrupted sleep, and decreased HRV before the user recognized symptoms of a cold, prompting rest and hydration. One downside is that the sleep/readiness score and stress monitoring can influence how you feel.
Design and Comfort
The Oura Ring 4 looks more like a premium accessory than a chunky fitness tracker. At 4 to 6 grams, it’s lighter than most rings and doesn’t interfere with grip strength during lifts. It’s also water-resistant up to 100 meters.
Value and Warranty
Starting at $349 with a $5.99/month subscription, the Oura Ring 4 is an investment piece. It is valuable for sleep optimization, stress management, and holistic wellness. The Oura Ring 4 comes with a one-year limited warranty against manufacturing defects and includes a 30-day satisfaction guarantee.

The Oura Ring and Weight Loss: Unveiling the Connection
While the Oura Ring 4 isn't directly marketed as a weight loss device, its comprehensive tracking capabilities can indirectly support weight management efforts. Here's how:
- Optimizing Sleep: The Oura Ring excels at sleep tracking, providing detailed insights into sleep stages, restfulness, and overall sleep quality. Adequate sleep is crucial for weight management as it regulates ghrelin and leptin, hormones that control appetite and metabolism. Sleep deprivation leads to increased ghrelin, decreased leptin, and a tendency to consume more calories, particularly from junk food. By helping users improve their sleep habits, the Oura Ring can aid in regulating these hormones and reducing cravings.
- Managing Stress: The Oura Ring's stress monitoring feature can help users identify and manage stress levels. Chronic stress elevates cortisol levels, which can increase appetite, promote fat storage in the abdominal area, and interfere with thyroid hormone production, all of which can hinder weight loss efforts. By providing insights into stress patterns, the Oura Ring can encourage users to adopt stress-reducing techniques.
- Tracking Activity Levels: While not as precise as dedicated fitness trackers for workout data, the Oura Ring tracks daily movement patterns and activity levels. This information can motivate users to be more active, contributing to a calorie deficit and supporting weight loss.
- Improving Overall Health Awareness: By providing a holistic view of health metrics, the Oura Ring encourages users to make informed decisions about their lifestyle. This includes adopting healthier eating habits, prioritizing sleep, and managing stress, all of which can contribute to successful weight management.
Oura's Personalized Approach to Metabolic Health
Oura takes a personalized approach to metabolic health tracking with Meals and Glucose. Meals delivers key insights about meal timing and nutritional content, along with AI-powered feedback from Oura Advisor to help you make informed dietary decisions. All you have to do is take a picture of your meal, and Oura does the rest. Foods can either fuel or negatively impact your performance, energy, and sleep. Oura encourages experimentation, since health is unique to each individual. The Meals feature helps you understand how your dietary choices impact your health, so you can improve energy levels, identify nutritional imbalances, and stay on track toward your goals by labeling each component, such as protein, carbs, and fiber, as low, moderate, or high. With the Oura and Dexcom partnership and integration, you can track your glucose levels directly in the Oura App using the Stelo Glucose Biosensor, encouraging you to focus on the bigger picture of your blood glucose over time.
Real-life examples
- One user, Tricia, only noticed small improvements in her RHR and HRV week by week.
- Another user, prior to Bailey’s gastric bypass surgery, her lowest resting heart rate (RHR) averaged around 85 to 90 bpm. Now, since the surgery, she has lost 110 pounds and her RHR is in the low 60s. Also, her Sleep Score used to be very low, but now she's consistently going to bed at 9 or 10pm and waking up every day between 8 and 9am and she feels so much better.
- Before losing weight, another user's RHR was in the 70s, but now it’s in the 50s, sometimes even the 40s.
- Brian discovered he wasn’t sleeping well. His sleeping habits were making him grouchy, irritable, and miserable. Using the Body Clock feature and sticking to it! When he started sleeping better and working out regularly, he became a more empathetic leader at work and in his personal life.
- Another user has been sober for 26 years. Oura taught him a lot about creating an effective workout routine as he started noticing on Oura that he wasn’t recovering well. So he mixed it up and now does a combination of strength training, high-intensity interval training, and running to avoid overworking one particular muscle.
Potential Drawbacks
Despite its numerous benefits, the Oura Ring 4 has some potential drawbacks to consider:
- Cost: The initial cost of the ring, combined with the ongoing monthly subscription, can be a barrier for some users.
- No Display Screen: The lack of a display screen means users must rely on their smartphones to view stats and insights.
- Fitness Tracking Accuracy: While the Oura Ring tracks various activities, its accuracy may not match dedicated fitness trackers or smartwatches.
- Bulky Design: Some users find the Oura Ring 4 to be bulky and uncomfortable, especially compared to traditional rings.
