Customer Ratings & Reviews

Love it very much my wife and daughter love too so far

I enjoy tracking all of my health data, but this ring tarnishes very easily. The gold has scratched so much that it almost looks silver now and I have had it for less than a year.

I recently upgraded from the Oura ring 3 to the Oura ring 4. Physically, the two rings look somewhat similar, although the Oura ring 4 is slightly thinner and lighter in weight. The more dramatic and immediately noticeable changes are the new color and design of the charging base/cable and the elimination of the three raised sensor indentations that were inside the Oura ring 3. I included a side by side photo of both ring interiors showing the indentions on the 3. I opted for the matte finish “stealth” option with the Oura 4. My Oura 3 was polished silver which, although really nice looking initially, started to accumulate noticeable tiny scratches and nicks scratches after a while. I wear the ring 24x7 and don’t typically baby it. Therefore, I’m not completely surprised it has several nicks, especially with that style finish. The blemishes aren’t obvious and are only visible up close. They also don’t affect usability or reliability of the ring at all. I’m hopeful the matte finish of the Oura 4 is more resilient to similar small scratches, even if only for aesthetic purposes. Both the Oura ring 4 and 3 are comfortable to wear and unobtrusive in most instances. As I did when ordering the Oura 3, I first measured my ring size using the Oura sizing kit and wore the sizer for 24 hours to account for slight swelling and changes in the finger size throughout the day. The nominal purchase price of the Oura sizing kit can be applied as a credit towards the price of the ring with many merchants. The Oura ring tracks sleep, readiness, activity, and vitals in several key areas. I don’t know how long the data is officially retained on Oura’s servers, but my historical data is still available back to when I first began wearing the Oura 3 in early 2023. Sleep tracking has always been my favorite feature of any tracker, and the Oura ring has been helpful for me with improving my overall sleep quality. It tracks timing, latency (time to fall asleep), sleep stages, and overall effectiveness. This allows me to identify and address areas where I’m having the most trouble falling or staying asleep. Oura breaks down the REM, light, and deep sleep stages individually. It also tracks heart rate/heart rate variance, body temperature, blood oxygen levels, sleep interruptions and disturbances. The app will offer sleep improvement suggestions based on the above measured biometric data. For example, it will suggest avoiding certain activities or practices before bedtime if the heart rate is elevated throughout the sleep cycle. Oura also tracks daily readiness, which it determines based on several individually tracked biometrics. It can reveal whether my body is recovered and ready for a productive day, or still tired, recovering and best to take it easy. It also tracks stress levels and stages throughout the day, activity, heart rate, cardiovascular age, and resiliency. The newly updated Oura app is easier and more intuitive to navigate. The most frequently accessed features have been moved prominently to the top of the main screen for more convenient access. The app allows users to generate time interval based reports that can be shared with health professionals or wellness experts. It even has social rings for keeping up with friends and family. Stats are sync’d to my phone every morning when I open the Oura app. One of the only shortcomings with both rings is that the app must be open and running to sync data. There is no passive sync. Also, the ring must be near the smart device to sync. The Oura 4 ring and updated app do however seem to sync much faster than the Oura 3 and prior app version. I’ve used Oura extensively in both iOS and Android. The app works reliably well on both operating systems and their respective devices. The Oura four makes a few operational improvements on how data is measured. One improvement that I am relieved was finally implemented is with activity tracking. On the Oura three, I had to manually trigger recording of exercise and physical activity. If I took a walk or jog, I had to first manually start tracking the activity in the Oura app. Doesn’t seem too bad in theory but there were numerous occasions where I performed workouts that weren’t recorded as such and were instead treated as regular steps. Like smartwatches, Oura can now sense the start of physical activity and it begins logging automatically. The ring still lags behind more powerfully equipped and GPS enabled smartwatches and smartphones when it comes to more advanced fitness tracking and workout metrics, but it’s good enough for basic activity tracking. Oura would not be my first choice or recommendation as a workout companion for highly active people. It’s much better suited as a passive biometric measuring device with basic workout tracking. Oura ring membership is not mandatory, but realistically it is required to experience the full benefit if the ring. In addition to health tracking, it offers other wellness features, like guides and exercises for meditation, sleep, stress relief and more. Whether or not membership is worth the monthly cost honestly depends on each specific individual. I am personally enjoying the Oura 4 to date. It seems slightly faster, more reliable, and feels lighter and even less noticeable on my finger than my Oura 3. Nothing is perfect and Oura has always had a few shortcomings compared to a smartwatch or dedicated fitness tracker. However, what it lacks in advanced fitness tracking features it more than makes up for in form factor and ease and comfort of 24x7 nonstop wear. Lastly, the battery life of the Oura ring is typically 2-3 times that of a typical smartwatch and it fully recharges quicker. I usually get a week of wear between charges and the ring typically recharges within an hour or so. The first week right out of the box, the ring charge lasted eight days before indicating it needed a recharge at 25%.

I love my Auro ring! It’s a great purchase so that I can monitor my health daily.

As much as I love the Oura ring, (this is my second ring) am very unhappy with my gen 4 gold ring I have had 7 months. I would never had paid the extra for the gold if I had known the gold would wear away so quickly.

I received my ring. I charged it without issue. I wore it for one week, and it started to come apart. So I say, don't wash with warm water and soap. I got a replacement ring from the manufacturer. The app for the ring is easy to understand.

love this ring!! i keep track of my stress and cycle!

Love the ring. I have the gold and it has tarnished a bit already

The Oura Ring Gen 4 is truly a remarkable feat of engineering. It looks like a normal ring, no one has been able to tell that I’m wearing a smart ring. But anybody could make one with crummy sensors inside, a bad app, a bad finish, etc. Oura is different though. The accuracy is incredible, I’m finding little difference between actual medical measuring devices and the ring's data. If you are wanting to be more in touch with your body and health, this is the device to get. The app is thorough and extensive. In fact, I’m still finding data points it tracks and reading about what each means. The explanations of measurements and how to adjust your life accordingly are very helpful and in-depth. If you don’t know how certain measurements work, you will learn through this app. The fact that some of the more complicated measurements can take up to a month or two to establish a baseline feels trustworthy. They aren’t going to start giving you bunk data without establishing a trustworthy baseline. I think what held me back from previous Oura rings was that they highly suggested you wear it on your pointer finger. This time around with the Gen 4, you can put it on any finger! So I used it to replace my wedding ring and it’s like nothing every changed. Other than taking it off for a couple hours once a week to charge it. But it charges so fast and lasts so long that it really is a non-invasive piece of tech in your life. Overall, I absolutely LOVE this ring. My quibbles are small and few. My fingers have boney knuckles which usually requires a slightly larger ring, usually a half size, but unfortunately there are no half sizes. The ring is a little snug, but that is ideal for best measurement. Android also says that the app is a resource hog, but I haven’t noticed a big battery difference. I think the biggest problem is having to pay a subscription, but this is a high end device so I guess that should be expected. I highly recommend getting one, and when you do, make sure to use the sizing kit first to make sure you order the right size! Pros: Can wear on any finger now! 6-7 day battery life Very accurate measurements Explanations of the measurements Completely normal looking ring now Rose gold is a perfect color Cons: Can be hard to understand what to do with this data No half sizes, which is a struggle for my knobby fingers Android says the app is resource hog Would love haptics for notifications so I could ditch my smart watch Subscription required for a lot of features

Great ring! Love the technology and the data this ring gives!!

Excellent quality.. perfect complement to apple watch

Love the information i can gather on my sleep and recovery

The Oura Ring 4 is the fourth generation of this compact health and activity data monitoring product. It supersedes the Oura Ring 3 which has been available since 2015. The new Ring 4 is an improved, slimmer version with more sizes for a better fit, better sensors and longer battery life. Oura Health was founded in 2013 and is based in Oula, Finland. Oura Health has become the foremost developer of wearable personal health data monitoring devices. It created its first Oura Ring in 2015 which has evolved to a new generation (Ring 2 in 2018, Ring 3 in 2021 and now Ring 4) every three years. The Oura Ring collects a variety of biometric readings more frequently than competitive devices and integrates that data in a well-designed app which provides advice on maximizing health and fitness. More than 2.5 million Oura Rings have been sold to date. Here are the key features of the new Oura Ring 4: • Oura Health Ring Generation 4 (Model JZ90-54220-12) • All titanium ring construction, six surface finishes: Gold, Rose Gold, Silver, Brushed Silver, Black, Stealth (dark grey) • Available in 12 sizes (#4 - #15), free (after credit) sizing kit available • Oura App provides extensive data analysis and advice to optimize health and sleep • Sensors integrate with app to monitor: Sleep quality, sleep apnea, heart rate, heart rate variability (HVR), temperature, blood oxygen, cardio capacity, cardiovascular age, stress, activity, resilience, menstrual cycle, body clock • Recessed Sensors: Red/IFR LED (Blood oxygen), Green/IFR PPG (Heart rate, variability, respiration), Digital temperature (Body temperature, variability), Accelerometer (Movement, activity) – more than twenty biometrics continually monitored • Smart sensing algorithm adapts to skin structure, tone and activity, optimizes battery life • 18 signal pathways improve accuracy and continuous reading capability of sensors • Memory capacity: One week of activity and sensor readings • Automatic firmware update via Oura App • Bluetooth Low Energy connectivity, 30+ foot range, EMF-safe, airplane mode available • Lithium polymer battery 15mAH (#6)-22mAH (#13) provides 8 day life, full recharge in 90 minutes, daily recharge in 15-20 minutes • Waterproof to 328 foot depth • Operating temperature range: 14 degree F – 129 degree F • 5 VDC wireless charging dock and 38” USB-C to USB-C recharge cable included • Dimensions: 7.9 mm Width, 2.9 mm Thickness, 20 mm (#4) – 29 mm (#15) Diameter • Weight: 0.2 ounce (ring), 2.3 ounces with charger and cable • Made in Estonia • One year warranty on parts and labor Setup: When you open the Oura Ring 4 box you will find a QR code to download the Oura app. This is the essential element to analyze and manage the data generated by the ring. To set this up, just enter your email address. Then you are given a link to Oura website. At the Oura website, create a unique password and you are given a code which allows you to register the ring, connect the ring via Bluetooth and update the firmware. Then enter your personal details (country, age, weight, height, sex) to enable the Oura app to properly interpret the biometric data generated from the ring. If you are an iPhone owner, the Oura app will connect to Apple Health to integrate and access the data stored there. A brief questionnaire will help the Oura app to focus on your health and fitness goals. While you are doing the setup, unpack the Oura Ring and set up the charger. (By the way, the charger is sized to match the ring size, so it is not interchangeable with rings of other sizes.) Place the ring on the charger to top off its battery. When fully charged, the white charger LED changes to green. If a ring’s battery is fully depleted it will take up to two hours to recharge. The battery life is substantial and should last eight days without recharging. I found that the battery drain is about 15% per day. By placing the ring on the charger each day while I was in the shower (15-20 minutes) the battery was restored to full power. Once the Oura Ring is fully charged, put it on your finger and rotate the ring so that the indentation is on the palm side of your finger. The ring should fit snugly and there should be no significant gaps between the ring and your skin. You may find that you can also wear the ring on other fingers. I found that sensitivity was very good and the ring generated accurate data even when on a finger slightly different in size than the finger for which you selected the Oura Ring size. The Oura Ring 4 has several advantages over its predecessor – it is thinner, lighter and the sensors are all recessed so it is more comfortable to wear. Plus it has more sizes so it will provide a better fit. It is also more durable since it is all titanium with a decorative surface finish. If you engage in activities which may scratch that finish (e.g., working out with weights) you can buy inexpensive silicone covers for the ring to protect it. Use: If you own an Apple Watch or other fitness watch you are conditioned to glance at the watch to read various data while exercising (heart rate, pace, calories burned, distance, steps, etc.) The Oura Ring has no display, so you must access the Oura app to see the data being generated. The only display is a red or green glow which indicate when your biometric measures are below (red) or above (green) normal. The Bluetooth Low Energy wireless connectivity provided a solid signal up to 50 feet from my phone and was very stable in all conditions. However, even if you do not have your phone with you, the Oura Ring will store data internally for up to eight days of use. When you bring the phone back into proximity it will synchronize and download all stored data. The key to effective use of the Oura Ring 4 is to allow it to build a solid baseline of your biometric data. This takes about two to three weeks of continuous use. During this learning period the Oura app becomes better and better at assessing your health condition. It uses this assessment to give you advice on the activity each day which will optimize your health, fitness and sleep. The app is also excellent at giving you a quick summary of your current condition (Readiness, Sleep, Activity, Heart Rate, Stress) – much better than the Apple Health app. Is it accurate? Both independent and Oura-sponsored research have confirmed that the Oura sensors provide data as accurately as specialized medical equipment. The Oura app works well to integrate and track all of this data so you trust its conclusions. Since I have worn an Apple Watch for five years and use it to track my exercise activities I was curious if the Oura Ring 4 would be a substitute, supplement or irrelevant for Apple Watch users. First, it is obviously not a substitute since it cannot offer any data readout by glancing at it during a run or bike ride. But does it offer enough additional value to justify it as a supplementary device? The answer depends upon your willingness to follow its AI-inspired daily advice and your general health condition. There are three categories of users who will certainly benefit. First, the truly committed health enthusiasts who seek every bit of data on their condition. Next, those with specific health issues who need to monitor those conditions. Finally, those who want to continuously monitor their health but don’t want to wear an Apple Watch when sleeping or in social settings where wearing the Watch is inappropriate (e.g., a formal event.) However, in all cases, keep in mind that the Oura Ring 4 is part of a system which includes a near-mandatory subscription to Oura Membership ($6/month or $70/year) in order to access all of the analysis and advice available in the app. I wish that Oura would simply offer a lifetime membership as part of the purchase price. Bottom line? The Oura Ring 4 is a marvel of compact, effective technology. The Oura app is superb and nearly all users will gain great utility from its data analysis. I love the product but have some qualms about the need to maintain membership for $70/year so I am giving the Oura Ring 4 just four stars. I recommend it, but only to those who recognize that ongoing cash commitment. But aside from that if you purchase the Oura Ring 4 I think you will be delighted with its subtle elegance in appearance which hides its awesome technologic power.

I got the new Oura Ring 4 a couple weeks ago and have been wearing it every day since it arrived! I wasn’t sure how much I would like it, but I knew I needed a product like this in my life. I’m not in the best shape right now, so anything that helps motivate me to move more and become more active, is good and something I need. The ring arrived quickly, within just a couple of days of shipping, and was well-packaged, in a nice little sturdy cardboard box, carefully protected to avoid any damage in transit. Unboxing the ring was exciting and the minimalist, elegant packaging made it feel like a premium product right from the start. Inside the box, the ring was securely positioned on the charging base, with the charging cable held in place around the charging base. The ring comes with clear instructions that make getting started simple and straightforward for anyone. It’s pretty obvious that Oura pays attention to presentation and user experience, with the packaging offering a great first impression of their product. The setup process for the Oura Ring 4 is really easy. I popped the ring on to the charging base, connected it to power, and let it charge fully for a few hours, before doing anything else. This step is crucial to maximize battery life and to make sure the ring is ready to be used and won’t run out of power during the first few days as it works to calibrate your body activity and get to know you and how your vitals. The charging process itself is really quick, and so far it seems that a full charge lasts me about a full week, which is a lot longer than any other wearable health tracking devices I’ve tried in the past. Pairing the ring to the Oura app on my phone was easy and only took a few minutes. Once it’s all charged, and paired with the app, you are ready to start using your new “health companion”. Aesthetically speaking, the ring itself is a good looking piece of technology, in fact, I’d go as far as to say that the Oura Ring 4 is stunning. I chose the gold finish, for a touch of elegance and class, in my opinion, and the polished finish gives it a sleek and stylish look that blends perfectly with your normal jewelry, which I do wear. At a glance, and even when you take a good long look at it, it really looks like a traditional gold ring, which I love. Sliding it on for the first time, I immediately noticed how smooth and comfortable it felt on my finger. The titanium shell on both the inside and outside makes a huge difference. It’s solid without being bulky, and the rounded inside makes it easy to take on and off. When you wear the ring, there is a small notch on the outside that you need to keep positioned towards the palm side of your hand. It’s the LED light that lights up when charging or when the power is low. I like that you can feel the notch, ever so slightly, so that you can verify it’s in the correct position even if you can’t see it in a dark setting. Over the past two weeks, I’ve been wearing it through all my daily activities, while sleeping, during my workouts and even while cleaning house, and after all that it still looks as good as new. Despite a few accidental bumps, there aren’t any major scratches yet, which is a really good sign and a signal of its durability and how well it’s going to look months and years from now. One small suggestion, for a future model, is that I wish the titanium finish wrapped around the edges to give it a truly seamless, solid-gold look. You can see the layers on the edge of the ring, but you do have to look pretty closely to see them. This ring is my very first fitness ring, although I have used fitness watches in the past. While watches are packed with great features to track your health, I never really stuck with them. It’s just not comfortable for me to wear a watch all day and night, especially when sleeping. With the Oura Ring, it took just a couple of nights to get used to wearing it while sleeping, but now I don’t even notice it’s there. I really appreciate how light and comfortable it is, yet it packs all the fitness and health-tracking power of a full size watch. It really is a perfect design for a fitness product. The functionality and amount of data you get from the Oura app is huge! From sleep stages to daily readiness and stress levels, the app gives me an incredible amount of information at my fingertips. Information I can use to make myself healthier and challenge myself to be more active. The insights it offers are easy to understand, even for someone new to fitness rings or fitness trackers in general. Not only does the app provide all of your vitals data, it also makes suggestions on how to improve yourself and it alerts you if something looks wrong or you might need to check on something. It notices changes in your routine and it flags those moments, asking you to provide details about what you were doing differently at the time. Whether that be working out, walking the dog, or maybe you were in a stressful situation, an argument or got some bad news. YOu can let the app know what is happening so that it better tracks that type of activity in the future. I’m so happy to have access to my vitals all in one place now, and with reliable insights that I can trust, and are only going to get better over time. I’m especially impressed with the sleep tracking features, giving me the ability to learn more about a part of myself that was previously impossible, well, because I’m sleeping, lol. I’ve been able to see patterns in my sleep quality which helps me make smarter choices about when to wind down or how my day affects my rest and how my rest affects my day. This ring is a game changer for me. Giving me constant access to my health information has already made a difference in my routine. As somebody who works from home, I tend to sit for long periods of time at my computer, but now, the Oura app notifies me when I’ve been sitting for too long and lets me know that I need to get up and take a quick walk, or stretch. I’m a little out of shape and looking for ways to improve my fitness, and the Oura Ring feels like a personal health coach right on my finger. It’s a great reminder to stay active and listen to what my body is telling me. The readiness score, in particular, has been a useful gauge to know how prepared I am for physical activity each day, and it motivates me to take it easy when I need to recover or push harder when I’m well-rested. I’m so happy to have this ring, and I really don’t have any bad things to say about it. After about two weeks with the Oura Ring 4, I honestly couldn’t be more pleased. It’s a powerful piece of technology, wrapped in a beautiful, durable design, with a user-friendly app that brings all of my health data together in a meaningful way that’s easy to understand and put into action. I’d recommend this ring to anyone interested in taking charge of their health, whether you’re a fitness enthusiast or just looking to improve your overall well-being. The Oura Ring 4 is a high-tech, 24/7 health coach that fits on your finger, and I’m excited to have it as part of my daily life. Thank you Oura!

Love the ring concept just don’t like the brushed look. It looks cheap.

I like the raadings i have managed tou dersts d how to get. Very techie little thing.

I’ve been extremely impressed with the Oura Ring. It’s sleek, comfortable, and easy to wear 24/7. The sleep tracking is outstanding, giving clear, actionable insights into sleep quality, recovery, and readiness without feeling overwhelming or gimmicky. What really sets Oura apart is how well it connects the dots between sleep, activity, stress, and overall health. The daily readiness score is surprisingly accurate and helps me make smarter decisions about training, rest, and recovery. I also appreciate the focus on long-term trends rather than just daily numbers, which makes the data genuinely useful. The app is clean, intuitive, and well-designed, and the battery life is excellent compared to other wearables. If you’re looking for a low-profile, high-quality health tracker that prioritizes sleep and recovery without the bulk of a smartwatch, the Oura Ring is absolutely worth it.

Best buy will not honor warranty. Oura keeps saying that it is best buy responsibility. Oura said it is covered but the inly way is through the retailer which is best buy. I have called multiple times and they both keep pounted the finger at each other.

The Oura 4 is hands down the best fitness ring available. It looks great (I got the stealth color) and so far I've found it to be super durable. I'm amazed at the technology Oura has been able to pack into such a tiny package. The ring is hardly bigger than the average wedding band, yet it senses heart rate and heart rate variability, blood oxygen levels, temperature, and it has an accelerometer to track movement, including steps and movement while you sleep. And somehow they figured out how to pack into it a battery the lasts for 8 days. Speaking of sleep, sleep tracking is my favorite feature. I don't sleep well, so knowing what's going on with my body is important for developing a sleep plan that optimizes efficiency. I've used watches to track my sleep in the past, and always suspected they weren't very accurate. The watch would indicate I was getting 8 hours of sleep, but somehow I still felt tired. I compared my watch with the Oura Ring 4 and while the watch was saying 8 hours of sleep, the Oura 4 was saying 6.5 hours, showing me an accurate picture of when I actually got to sleep, and how long I stayed there, as well as giving me ideas on what I can do to sleep better, with reminders to take specified steps. And most importantly for me, it showed me when my O2 levels dropped off. I have mild sleep apnea, so keeping an eye on that is important for heart health. I honestly can't say enough positives about the Oura 4. The ring is gorgeous and functional. The app is really good, as well, breaking down all data for you and putting the information in an easy-to-read format. I'm pretty sure I haven't even touched the surface of what can be learned from the app, but I'm getting there. I highly recommend the Oura 4, whether you're a fitness guru, or you just want to understand your body better.

It’s a cool product but you have to pay a yearly fee of $70 to see most of the things you bought it for. Other than that I like it.
