Customer Ratings & Reviews

I wanted to like this but I just don't it isn't accurate and the fit isn't good it will fit one day and then the next it is to small I don't know if it is cutting circulation and my finger swells or what is happening but I don't like it. I have figured I'm the type of person who likes to see the progress and what is happening without pulling out my phone so this is a no for me.

I love this! So helpful to track stress, health markers, and sleep.

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.

So happy with this purchase. The insights it providers are so awesome.

Very happy with my purchase it’s comfortable and easy to use

Great Product, really brings self awareness to health!

Cool ring lots of insights fast charging overall good buy

Quick Overview ================================= I was very curious to see how a smart ring would fit into a "smart fitness device" ecosystem. They've been out for years - led by Oura - and this is their 4th version. The Oura Smart Ring 4. With no display and no vibration for feedback or notifications, could this be useful and/or replace a smartwatch or fitness band? Overall build ================================= After completing the sizing using Oura's sizing kit, you'll order your Oura Smart Ring 4 which comes with a charging stand that the ring sits perfectly into. I chose the "brushed silver" version and it looks and feels great! The etching they did on the surface somehow really catches the light while looking matte. It's hard to describe, but it really is interesting to look at! I read that it's made entirely of titanium so it should be quite sturdy. Externally, you'll see a small divot or dimple. That helps you wear the ring properly. That dimple should face in on your palm side. If you look inside the ring, you may catch some of the lights and sensors that line the inside portion. There are more sensors than the previous generations and should account/allow for some of the ring spinning that will happen during a normal day. Whenever I could, I tried to make sure the dimple was facing into the palm side of my hand. Once you set the ring onto the charging stand and plug in a USB-C cable, the light will glow and you can then open the Oura app (Android, for me) to set up the ring. It should see the ring right away and you'll complete the setup by answering a few questions and allow the application to access the things it needs to track your location and activity. Once that was done, it was time to do testing - which just means wear it for 5 days or more, and see how it goes. The ring is waterproof, so taking a shower or bath is no problem. Performance ================================= In testing, I wore the ring for 3 days before the battery indicator (in the app) showed less than 30%. At that time, I charged it and put it back on when it was full. Supposedly I could have pushed this for 2-3 more days, but I didn't want it to end up dead if I was out and about. As you can imagine, since the ring has no display, no indicator lights, nor any vibration for notification, you must check the app for everything. Luckily, it's a pretty nice app! At the top, you'll see things like "Readiness" (did you have a good, restful sleep?), "Sleep", "Activity", and "Heart Rate" so you can get some "at a glance" info, and below that you can dig into things like your actual activity, heart rate, and sleep. As you click into each one, you can get more details about your sleep quality, REM sleep, deep sleep, etc. During the setup, you may have selected some of your favorite activities. For me, I chose tennis, table tennis, and walking. As it tracks activities throughout the day, it will make a best guess regarding what you might have done. Later, you can check the app and confirm or edit what it guessed. I really liked that compared to my Fitbit Charge 5 which doesn't do much regarding activities it doesn't recognize. The 3 sections at the bottom include Today, Vitals and My Health. Today gives you your daily snapshot of activities as expected. Vitals lets you dig into the stats a bit more, while My Health is supposed to give you more updated data after gathering data for up to 2 weeks. As of now, since I've been testing for a week, it says that each category is still "calibrating". After gathering this data, I'd assume it could get a more accurate baseline of my activity and stress levels to better alert me when I may be feeling stressed, etc. Stats-wise, if I compare this to my Fitbit Charge 5, the steps are usually within 1-2% so I'd say it's pretty accurate. My sleep tracking seems more accurate with the Oura 4 because my Fitbit will mistakenly think that reading in bed is sleeping time! With the Oura Smart Ring 4, I haven't had to edit or correct the sleep times. Apparently some independent studies have shown the Oura is very accurate (5% more than Apple Watch and 10% more than Fitbit). All of this accuracy and comfort does come at a price. The price of the ring which is up there with a high-end smartwatch, and the subscription which is $70 annually. I do love the data and the application as a whole, but it's up to you if you think that price is worth it for data and a device with no display or native notification capabilities. Conclusion ================================= Could this be your only fitness tracking device if you're somewhat of a minimalist and like your classic analog watches? Yes, I think it gives you a wealth of accurate data that you'd have to check in the app, of course. Could this be your secondary fitness tracker if you already have a smartwatch? Maybe, but the value proposition gets quite a bit smaller. It's within 1-10% of a smartwatch's accuracy, but it has no display nor vibration for notifications. It does have a great app that has a lot of information, and it's comfortable to wear for long periods of time. I'd recommend this highly for those that don't want to invest in a smartwatch or fitness tracker since it's very unobtrusive and gets you nicely presented, accurate data. As a "backup" or secondary device to a smartwatch, I'd say get it if you don't like your current sleep tracking stats (I'm looking at you, Fitbit!).

Love it. Still learning more each day. I have my hands in all kinds of cleaning products. It has held up nicely.

It works and it came when it was supposed to. I enjoy Best Buy shopping. Easy to work with.

My only concern is they scratch very easy. Get a protector/ cover.

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.

The Oura 4 Ring is perfect for my situation. As someone who bought a nice, self-winding mechanical watch for myself, using a smart watch or wrist-worn fitness tracker is something that just wasn’t going to happen…no matter how informative it could be for a variety of health-related parameters. The Oura 4 solves that dilemma elegantly and conveniently. Clark Howard, the consumer advocate who used to be on the radio and now has a daily podcast to go along with his web site, has been vocally enthusiastic about his Oura ring for as long as I can remember. And as someone who admires what he does and his commitment to improving the lives of others, I was excited when the offer to review a new model of Oura ring was made available to me. The Oura 4 Ring is designed to monitor and give you insights into Sleep and Rest, Wellness and Longevity, Activity and Fitness, Heart Health, Women’s Health, and Stress. I found the longer I wore the Oura ring, the more information it collected from me, and there was more feedback on more topics which I received via the app on my phone. I have seen mention of the large number of biometrics that the Oura 4 can track (Oura claims “over 20” on their web site), but I have been unable to find a comprehensive list of what exactly is tracked - and that could be for good reason when it comes to competition in the marketplace for this type of product. And speaking of tracked, I could not find any evidence in my phone that the Oura App was tracking my location. I received a new iPhone literally on the same day my Oura 4 Ring arrived (my old phone was three years old). So, I had an accelerated learning curve with new-to-me technology. I will say that the Oura ring caused me no set-up or connection issues with the iPhone 16 running the latest OS. I wish I could say the same regarding some other devices in my life. The Oura App provides you with a wealth of information that at first can seem daunting. It does take awhile to digest all the data that is being collected and how it is being presented to you, and I am still working on that part of the experience. That being said, it just goes to show that the Oura 4 Ring is a serious tool that has wide reaching use for monitoring the body and provides guidance for a properly motivated individual to make any number of positive changes to their lifestyle. To make changes, one has to know what to change, how to change, and most importantly be able to monitor the effects of those changes. If you can’t easily see changes, you are likely to lose interest in continuing to try to make those changes. Even though I am someone who doesn’t have a regular workout routine, I have more than a passing interest in the pedometer function on my phone. But I don’t always have my phone on me during my daily activities for a variety of reasons - usually because I don’t want to inflict damage to the phone, or having it in my pocket is inconvenient or uncomfortable. Having that functionality built into a ring, now THAT is convenient. Same thing with monitoring my sleep. I’ll be the first to admit I have poor sleep habits which seem to have become worse once being retired and having no regular routine I have to follow. The Oura ring provides me with the necessary monitoring and feedback, and notifications to subtly prod me into better habits. Reviewing the daily data, I am pleasantly surprised as to the depth of detail and the accuracy of it. While Oura makes mention that their rings are not medical devices and should not be used to diagnose, treat, or monitor specific heart problems, I am looking forward to being able to have a heart rate monitor on my body virtually all the time to alert me to episodes of A-fib that I am being treated for. The cardiologist I work with has had positive things to say about certain smart watches and their ability to track cardiac issues, so I am looking forward to hear his take on fitness rings and their place in this area. The Oura 4 Ring is designed to be worn no matter what you are doing. The Oura App also syncs with numerous other health and fitness apps so you don’t have to give up using monitors you maybe already be familiar and comfortable with. The ring is made of titanium on both the outer surface that gets exposed to the ravages of everyday living and on the non-allergenic inner surface that spends its time in contact with your skin. I found the Oura 4 to be no less comfortable than a traditionally sized wedding band. Battery life during my somewhat short introduction to the Oura 4 has been what the manufacturer claims and the same with recharging time. The app prompts you to recharge your ring overnight when the battery life gets down to about 20 percent, but since tracking my sleep is one of my priorities, I usually charge it during the day when I am performing a low-exertion activity. The app alerts me when the ring is fully charged and the time it takes is relatively short. I have seen mention made that other fitness rings come with a charging case so you can conveniently recharge the ring when traveling. Considering the week-plus that the Oura lasts between charges, I think this would affect only a small fraction of potential users. One thing I found interesting was that the ring sizing kit that Oura sells (with a credit upon purchasing the ring at most retailers) is that it states the ring can be worn on any finger of either hand for monitoring purposes. When I looked at the information on Oura’s web site about their leadership team, I noticed that in the pictures provided, just about everyone listed wore the ring on their index finger. I have a nagging feeling that there is a reason for this and I maybe would have thought twice about choosing my ring finger since that is what I am most comfortable with. Maybe I will change when I have to replace this ring - it is a piece of technology after all with a limited life due to the built-in battery. I still have a lot to learn about what is tracked and the personalized guidance that the Oura App can make when it comes to my health and wellbeing. Considering the number of smart watches I see, if I were Oura I would concentrate on the market consisting of watch enthusiasts who gravitate towards mechanical watches. The idea of a fitness ring is a no-brainer for those of us wishing for this type of monitoring but are reluctant to give up our beloved timepieces. Oura, I love the execution you have made on this product and of the usefulness it possesses.

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 it very much my wife and daughter love too so far

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

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

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

Excellent quality.. perfect complement to apple watch

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%.
