PRODUCT Oura Ring 4 - Smart Ring - Size 12 - Stealth Model:JZ90-54218-12SKU:6595532 QUICK REVIEW First time Convert from Fitness Band to Fitness Ring In most cases it seems more accurate than my fitness band (FB), and it allows me to return to wearing a nice watch instead. Use the Sizing Kit and choose your ring carefully. The edges are somewhat sharp, which makes choosing a finger even more critical. The app is not as clear / easy as my FB app, but hopefully it will continue to evolve. In short, I recommend the OURA 4, with a few reservations, but especially if you want to free up your wrist from a fitness band it is a good option. MORE DETAILS PROs - Solid very well build and nice looking - Easy to use and to get started - Long Life between charges - Fast Charging - Good (enough) app CONs - Very Large compared to a typical wedding ring - Edges are too squared off, almost sharp - App is sometimes hard to navigate to find what you want SIZING / EDGES I did not spend enough time with the kit. I ended up moving the ring from my left index finger to my right middle finger (the only other finger that fit). One big issue for me is that the edges are too squared off. I scrape myself all the time. I don’t mean I’m drawing blood (yet), but one main reason I moved fingers is that every time I touched my face, I scraped it on the edge of the ring. Even on my middle finger, I am scraping myself while washing my hair / face. PERFORMACE (Coming from FB) SLEEP TRACKING I found the ring to be especially more accurate in sleep measurement. How do I know this? We had a smoke alarm fail on us, and it was going off every few hours. FB gave me a sleep score of 85 and 7 hours of sleep. The Ring gave me a sleep score of 60 and 4.5 hours of sleep. In other words, the ring knew I was up tossing and turning and the FB did not. The Oxygen readings on the Ring are also more detailed as FB dumbed down the stats a few years ago. I have borderline sleep apnea (as diagnosed in a clinic). The Ring is giving me all sorts of warnings, while the FB says everything is within normal range. STEPS At first, when I had the ring on my left Index Finger the steps were almost identical to my FB and within 10% of my digital dress watch. However, once I moved the ring to my right middle finger, it started recording about 20% fewer steps. I don’t know if this is because it is a tiny bit more loose or Right hand Vs Left hand (maybe 11.5 vs 12). Or maybe the way I hold the dog leash (makes up most of my walking). THE APP There is nothing particularly wrong with the App, it just not as optimized as FB. For example, if you are looking at a stat (STEPS / SLEEP) it shows you a LEFT or RIGHT arrow to go to the previous day. However, instead of just taking you to the previous day, it brings up a full calendar and you have to pick the date. Of course, this is not the end of the world just wasted time hunting for things in the app. WHAT DO I MISS GOING FROM FB TO THE RING? - Vibration Alarms on FB - Seeing the Time at Night Both of these were easily solved by stealing the Digital Assistant Clock from my spouse’s side of the bed! FINAL IMPRESSIONS I am amazed at the size, accuracy and battery life of something like this. It is a marvel of miniaturization. I wish the finish was rounded and it was not scratching me. I wish it was a little smaller, but had I sized it right I probably would have moved it to another finger resulting in a smaller overall size. Finally, it would be perfect it is has some sort of vibration alert / alarm. Yes, I will replace my FB with the ring.

The Ring was broken when I got it and would not charge

Oura Ring is a sleek and comfortable wearable that blends seamlessly into everyday life. Its minimalist design makes it easy to wear 24/7 without feeling bulky or distracting. The sleep tracking is especially impressive, providing detailed insights into sleep stages, quality, and recovery. I appreciate how clearly the app explains data, making health information easy to understand. The readiness and activity scores help encourage healthier daily habits without feeling overwhelming. Battery life is strong, lasting several days on a single charge. The ring feels durable and well-made despite its lightweight design. It’s great for people who want health tracking without a traditional smartwatch. The data feels accurate and consistent over time. Overall, it is an excellent choice for anyone focused on improving sleep, recovery, and overall wellness.

I've been slowly watching not only the emergence but rapid developments in smart health devices over the last decade and I've been wanting to try out a device here or there. I do use an iPhone and Apple Health has helped me track my activity levels, but to really take it to the next level I needed a device that interfaced directly with my body for true monitoring and analysis. The watch just seemed somewhat cumbersome and I'm not a watch wearing kind of person (yet) so I started to look at rings and Oura offered their Oura 4 so I took a chance. What I do like is it is a two step process. First, you get a sizing kit which is a series of pre-sized bands and you simply try them on till you find the fit that works for you. You then submit your size to Oura (along with band color, type, etc..) and they then set up a ring custom to that size with its own serial number. Ring sizes vary from 4 to 15 and depending on your finger selection, the sizing can and will be different. For example, my thumb is a 15, pointer and middle are 13 and 12 respectively but my ring finger is an 11 and that is the finger I opted to use. One thing I do wish is Oura offered half size increments. 12 was a little loose but 11 was just a touch too snug. I went with an 11 seeing as I wanted to make sure it was making proper contact. An 11.5 would have fit just right. After submitting my size, I was sent the actual Oura Ring itself in very smart packaging that includes an excellent presentation. Inside, you get the ring and its charging stand which is also very well constructed. It oozes Apple type polish. Even the included USB-C cable is nice and lastly you get a very small manual that has numerous QC codes to point you to not only the app which is required but other resources. The ring itself is very polished and nice looking. Oura says to wear it at all times, but I still find myself removing it to lift weights though. Setting up the ring was very easy. Download the app, have it find your docked ring via Bluetooth, pair and you're finished. A firmware update was immediately available. The app will lead you through numerous steps to help personalize your goals and to enable Oura to interface with Apple Health if you're using an iPhone. Lastly, it will ask to be allowed to send you notifications. I'm still in the process of letting Oura learn my baseline health and sleeping patterns so that will take another week or so (it says it can take up to two weeks). I was happy to know the cardio and strength training I already do has resulted in a sub 50 nightly heartrate and a sub 60 resting heart rate. It is nice to see my bpm react accordingly when I'm eating foods not so great. I found out my sleep was just ok and needs improvement and how many times I wake up in the middle of the night. It will even remind you to get up and move around if you work a sedentary job like I do plopped in front of a computer. It sets initial activity goals for you and will let you know how you're progressing during the day of achieving them even through basic day to day tasks. The Oura app really is designed to take all the data it can from your finger and extract every bit of useful info to help you know where you stand and where you want to go. It is the crucial piece of the puzzle that brings everything together. This is what seperates it from the Apple Watch right now is the sheer amount of data it provides you compared to the Apple Watch. Initially when I was wearing the Oura, it felt like it was in my way and distracting because I'm not used to wearing rings or watches. After a day or so, I found myself not even noticing it and it has pretty much become an extension of my hand and doesn't get in the way. Perfect, right? Not exactly. A subscription is basically mandatory to really get the proper use out of what can be a pretty pricey piece of health tech. The upside is the cost is only $6 a month or $70 a year but that doesn't change the reality that you will need to continue paying more after the initial purchase. Another thing is unlike Apple Watch, it can not read your blood pressure from your finger. It also can not do Electrocardiogram (ECG) either like an Apple Watch. As someone who likes to monitor their blood pressure, this was a major letdown. Lastly, as mentioned at the beginning, offering half sizes would have really let me dial in my ring size instead of having to select a size either a tad too snug or a tad too loose. Having taken this first step into smartwear for health, I can say I am liking getting all this data about my day to day cardiovascular health and how it correlates with everything I do. I may end up stepping up to another device that can do blood pressure and ECGs in the future, but for now the Oura is giving me exactly what I need to start this journey.

I bought it on December 2024 and now the battery is lasting just 24 hours!

The ring is too big and doesn’t read correctly. I got the size recommended at the store.

Best purchase I’ve made for my health this year. The Oura Ring has completely changed how I understand my sleep, recovery, and overall wellness. It’s stylish, lightweight, and doesn’t feel like a bulky fitness tracker. The battery lasts days, and the data is incredibly accurate. If you’re into optimizing your body and performance, this is 100% worth it.

The Oura fitness ring is a very insightful little device. I think what it helped me with most is my sleep and recovery tracking. It has learned my rhythm over use each day, recommended bed times and provided details about my sleep efficiency, restlessness, recovery etc. I find that when I wake up the sleep score and recovery scores are in line with how I feel. It helps me take it easier on days following poor sleep and pushing harder on days where I get good sleep. It’s handy to have metrics on sleep that provide clarity on how I feel each day. I’d say that’s one of the most useful features. From a comfort standpoint, this is where I’m taking a start away. The ring is kind of chunky. You never forget that you’re wearing a ring. Especially if you wear it on either your ring or middle finger, it will be pushing against your other fingers. I’d suggest wearing it on the index finger as is recommended, though I didn’t particularly like wearing the rings from the sizing kit on my index finger. Along with comfort, if you are wearing this ring while working out, it gets in the way of pulling movements. The ring digs into your hand and causes some wicked callouses and general pain/soreness. Pressing movements aren’t bad though. If you have a tendency to play with your ring, there is a notch on the bottom that indicates how the ring should be oriented, I can’t help but press on this with my thumb, then use it to rotate around, it’s begging to be fidgeted with. From a durability standpoint, I am already starting to notice some scratches in the finish. (Stealth color - dark grey/black) these scratches are located on the bottom of the ring, probably from the gnurling on the bar. The charger works well and charges fast, the battery lasts a really long time. If you take it off during showers, it generally stays topped off and ready to go. All in all, I like the insightful features along with the classic handsome styling. It definitely beats the older style with the large flat spot.

Oura Ring 4 - Smart Ring - Size 10 - Silver: A Must-Have for Health & Wellness Enthusiasts! I recently purchased the Oura Ring 4 in Silver (size 10), and it’s honestly one of the best tech investments I’ve made for my health and wellness journey. Before getting the ring, I was cautious about sizing, and I highly recommend using the Oura Ring 4 Sizing Kit to ensure the perfect fit. Sizing Kit: The sizing kit is an essential tool. It comes with plastic rings of various sizes, which helps you determine which fits your finger best. I thought I was a size 9, but after using the kit, I realized that size 10 was the more comfortable fit. I appreciate how easy it is to use and how accurate it was, eliminating any guesswork. Design & Build: The Silver finish is sleek, modern, and stylish. It doesn’t look overly techy or bulky, which I love. It fits well with almost any outfit and blends seamlessly into everyday life. The lightweight design makes it so comfortable that I forget I’m wearing it most of the time. Features & Performance: The Oura Ring 4 delivers amazing features when it comes to tracking sleep, activity, and overall health. I’ve been using it for a few weeks now, and the insights it provides into my sleep quality, readiness score, and activity levels are spot on. It’s a great companion for anyone looking to improve their fitness or sleep habits. Sleep Tracking: The sleep insights are incredibly accurate. It tracks different stages of sleep, your heart rate variability, and even body temperature changes, offering tailored advice to improve sleep quality. Activity Tracking: Whether I’m walking, running, or doing yoga, the Oura Ring 4 captures all of it. The activity tracking is super precise, giving me a detailed breakdown of my daily movement and resting heart rate. Battery Life: Battery life is impressive! It lasts for about 7 days on a full charge, and recharging it is fast. I rarely have to worry about it running out of battery in the middle of the week. Health Monitoring: The ring also tracks your heart rate, respiratory rate, and offers insights into how your body is recovering. Comfort: The size 10 fits perfectly, as I mentioned earlier, thanks to the sizing kit. The ring is comfortable to wear 24/7, even while sleeping or exercising. I was initially concerned about it getting in the way of my daily tasks, but it’s so lightweight and unobtrusive that I forget it’s there. Overall Impression: The Oura Ring 4 is perfect for anyone serious about tracking their health and sleep patterns. It has a beautiful design, excellent performance, and a ton of useful features. The Sizing Kit made the process of picking the right size easy, and I’m so glad I opted for the size 10. Whether you’re into fitness, self-improvement, or just want to monitor your wellness, this ring is definitely worth the investment. I would highly recommend the Oura Ring 4 to anyone who wants to track their health in a stylish, effective, and seamless way!

I’ve been using the Oura Ring for about two months now and it has become one of those things I check every morning without even thinking about it. The biggest value for me has been sleep tracking. The data feels detailed without being overwhelming. I like seeing not just how long I slept, but how my sleep quality changes depending on when I go to bed, if I drink alcohol, or if I work out late. It made me more aware of small habits that affect how rested I feel. The readiness and activity scores are also helpful. I don’t follow them blindly, but they’re a good reality check. There were days I felt fine but the ring showed poor recovery, and later I noticed I actually did feel more tired than I thought. Over time I’ve started pacing workouts better and taking rest days more seriously. Comfort-wise, I was worried about wearing a ring 24/7, but it’s been surprisingly easy. I barely notice it while sleeping or working. The battery life has been solid too. I usually charge it about once every 5 to 6 days. The app is clean and easy to use, and the trends over time are what really make it useful. It’s not just numbers, it’s patterns, and that’s what helped me change a few habits. It’s not perfect. The subscription model is a downside, and sometimes the activity tracking isn’t as detailed as a full fitness watch. But for what it’s designed for, recovery, sleep, and general wellness, it does a really good job. Overall, I’m glad I bought it. It’s helped me be more intentional about sleep and recovery, and after two months I feel like I’m getting real value from it.

This is a great idea and i would likebit even mor wif i disnr have to charge it every other day!!!!

I wouldn’t recommend this ring I had to get a new ring within 3 days and still not pleased

I really like this ring. The color is aesthetic, and the entire nature of it is easy to use. It looks good with every outfit, and it matches everything. I paired it with the Ark phone case, and now I feel like I have a great duo on my hand. The battery life is amazing, and I love opening the app every single morning and night to see what I need to work on the next day. I mostly use it to track my sleep, and the deal I got on this ring on Black Friday was amazing; almost $200 bucks off. I highly recommend the sizing kit so that you really know what size to get. I got the size 11 and first checked with the sizing kit if it's really my size, and then I found out that you need to get the Oura ring one size bigger that what you are. Best purchase ever! I highly recommend it.

I recently purchased the Oura Ring 4 in black, size 9, and I couldn’t be happier with my experience. The sizing kit made it very easy to find the perfect fit before ordering, which I really appreciated. The ring itself is sleek, comfortable to wear all day, and feels very high quality. The health and sleep tracking features are accurate and provide valuable insights that help me understand my daily habits better. Battery life is excellent, and the app is user-friendly with clear data and helpful tips. Overall, this is an outstanding product for anyone who wants to keep track of their wellness without wearing a bulky smartwatch. I’m very satisfied with my purchase and would definitely recommend the Oura Ring 4 to others!

Great device to track your readiness for the day. Easy setup and use. Design: It will look and feel big on your hand but once you wear it for a week, it actually isn't that bad. You'll get used to it. It does scratch quite easily but with care, I think it will last long. I have it for about 2 weeks now and I have very minor normal scratches on the bottom of the ring. I do not wear it during showers or when I was my hands. Usability and functionality: The information it provides is helpful to me. I have a history of pushing myself without letting my body heal or rest, which results into dizzy spells. By having this ring, it tracks my body's readiness and lets me know when I need to slow down. It does not track real time activities (e.g. running) but it can integrate or interface with other tracking apps like Strava (which is what I use for running). It will automatically receive the information from the Strava app and log it as an activity. The other features I like are the sleep and stress trackers. It gives me an idea of where I currently stand based on the data it receives. The longer you use it, the more accurate it will be. Overall, it's a great device to help you be mindful of your body!

As someone focused on mental health, physical recovery, and staying balanced while managing a fast-paced lifestyle, the Ourā Ring has been nothing short of transformative. I’ve used smartwatches and fitness trackers before, but nothing compares to the depth and accuracy of insights I get from this ring. From the moment I put it on, it felt like a seamless addition to my daily life — lightweight, sleek, and stylish enough to wear with anything. But it’s the data that keeps me hooked. The sleep tracking is incredibly detailed, helping me fine-tune my routines and understand my energy levels. The readiness score has helped me avoid burnout and push myself on days when I’m actually ready. What sets the Ourā Ring apart is how it helps me connect the dots between my mental health and physical activity. It’s like having a personal wellness coach on my finger 24/7. With my history of addiction recovery, having a tool that encourages mindfulness and balanced habits has been a lifesaver — literally. Battery life is stellar (I charge it every 6 days), syncing is flawless, and the app is intuitive with beautiful visuals that make me WANT to check in on my progress daily. Whether you’re an athlete, a biohacker, or someone on a personal wellness journey like me, I can’t recommend the Ourā Ring enough. If you’re on the fence — take the plunge. It’s more than a ring; it’s an investment in a better version of yourself.

I was really worried about the ring being bulky but its not at all! Most of the time I forgetting I’m even wearing it until I go to use my left hand to twist off a soda or water bottle cap since I wear it on my left thumb. I debated about which hand and finger to wear it on and narrowed it down to my left hand and either my pointer finger or thumb. I bought the sizing kit and wore the size on each finger for a few days at seperate times. My thumb was the most comfortable for me, like I mentioned I forget I’m even wearing it until I randomly decide to use my non dominant hand to untwist a bottle. Typically the only time i take the ring off is for showers - usually I will set it on the charger during that time mostly so it doesn’t get lost. The battery so far has never even been low. The only reason i take it off for showers is more so habbit taking off all my rings during that time. Overall i am very happy with it so far. As for accuracy its pretty close to the data i get on my apple watch, it’s not 100% the same but for what I want it for it does the job which is better tracking my sleep and tracking my stress. For sleep I do notice if I am laying down completely relaxed but not sleeping yet it sometimes will say i was asleep or took a nap, other wise it’s pretty accurate tracking such if i wake up in the middle of the night. Overall its great for what i use it for - the subscription although does kind of suck its quite reasonable and, again for what I want the ring to do, worth it.

First time Oura Ring user here but longtime wearer of heath tracking devices. I’ve known about Oura Ring for years but only now was motivated to try one. Simply put, I presumed, at best, it just duplicated my smart watch’s data. Recently though I developed an interest in tracking sleep data to improving my sleep. Problem was wearing a watch to bed is uncomfortable. Secondarily, there are occasions where I ditch my smart watch for a dress watch. The result is I look sharp but create a data gap for that evening and what good is data if it’s incomplete. A ring solves both of these problems so I decided to give Oura Ring 4 a test. OURA APP & MY EXPERIENCE USING IT I’ve only worn the Oura Ring 4 for a few days now but it’s already apparent to me it’s a great companion, not a competitor, to my Apple Watch as I thought it would be. In fact, it integrates with Apple Health and Strava to fine tune its performance boosting and wellbeing suggestions. Of course, whether to share all or part of your data with 3rd parties is only an option. It certainly offers excellent advice and insight either way. What I’ve realized wearing the Oura Ring 4 is that while it’s frequently portrayed as a “fitness tracker,” that’s a misnomer. I see it as a holistic wellbeing tracker with an emphasis on sleep quality. It goals it to give you information and awareness of what the body is saying to improve one’s overall health rather than to, say, boost athletic performance. If you track your athletic efforts a watch is still necessary for real-time information like pace, stride, heart rate zone. The ring doesn’t have GPS so it can’t even record your route without help from your phone. Where the Oura 4 Ring excels over smart watches is how it aggregates fitness activity with daily activity and sleep for a comprehensive picture of your wellbeing. It then explains its graphs and numbers and suggests how to improve or maintain. My watch collects and displays a lot of the same data but it does a poor job of telling me what to do with the information to make meaningful improvements to my life. That brings me to the Oura app. It’s replete with insightful information and is by far the best health data app I’ve ever used because it does explain (like I was five) what it all means. Concepts like sleep heart rate variability can be muddy but the app illustrates what a certain pattern means to your sleeping effectiveness, both for a specific night and long-term trends in an actionable way. I’ve worn sports and smart watches for years but only the Oura app showed me how my evening runs, not far from bedtime, might be interfering with getting quality sleep so I’ve started to run earlier. And I’ve only been using the ring for a few days so lots more for me to discover. This is just one instance of the app’s usefulness. It’s so data rich there is no way I could touch on every data point offered. But the key areas are daily “readiness,” “activity,” “heart rate” (including stress), and the aforementioned “sleep.” The app uses all of these to alert me when it’s time to go all out or take a beat and to forecast wellness issues. For example, it constantly monitors your heart rate and displays in a graph making it easy to discern between a trend and a one-off event or having to wade through a bunch of numbers. But there is a catch, or more accurately a cost. All this detailed knowledge is only available with a $5.99/mo. subscription. Non-subscribers only get general scores for the above categories which severely limits the ring’s usefulness. I detest how everything has gone subscription model and I do my best to avoid them. But $6/mo. for a deeper level of advice and knowledge about my health is digestible even if the ring itself is pricey. When I ask myself if I’d rather have an extra $6 each month or this information, Oura wins ever time. THE RING The Oura 4 ring itself, to me, is the first version that looks and feels more like jewelry than a tracker. Unlike previous models it’s all titanium and the sensors are flusher to the interior. There are a couple sand-sized bumps on the interior, but I don’t feel them wearing the ring. Oura says it’s water resistant. I’m not going to test that but I’ve had no problems when hand washing. The build-quality feels solid, and its slim silhouette (at least compared to older models) is so attractive that I often forget it’s a tracker not jewelry. I blindly ordered the brushed silver color and had no regrets after seeing it in real life when it arrived. It’s matte with a variable sheen as lighting conditions change. In indirect light it’s muted otherwise it does have a touch of shine. If you want something more subdued Stealth is a great option. I think either of these colors more attractive than the standard black and silver colors and worth the upcharge considering the ring will be worn almost 24/7. But that’s obviously a personal choice. By the way, the fit of my size 10 ring is just a touch looser than the equivalent test ring in the Aura Ring 4 fit kit. I can manually twist it around on my finger, but it doesn’t turn by itself. If you want a proper fit spend a day with the fit kit’s “dummy” ring. Oura says battery life is about a week. I don’t know the use case to get that performance. My ring’s battery consumption has been about 20% a day which would come to a 5 day lifespan. I charge mine daily while in the shower. A USB-C charger is included. I’m surprised it’s not Qi wireless as the Oura Ring 4’s competitors offer. Hopefully Oura will develop one as an accessory. I feel the ring’s charger should be as travel-friendly and convenient as the ring itself. FINAL WORDS Bottomline here is there are many reasons to buy the Oura 4. It’s great for people who don’t like smart watches, but also for people who do wear them. It seems counter intuitive maybe, but the Oura 4 and a smart watch really enhance each other plus it’s never bad to have multiple data sources to compare. But most of all Oura 4 ring is an outstanding and comfortable sleep tracker. The app is intuitive and does a magnificent job at actually teaching you about your health rather than leaving you to figure it all out, and isn’t that really the reason to have a health tracker in the first place?
