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 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.

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

The Oura Ring 4 has been an excellent addition to our daily routine. The gold finish looks elegant and refined, and the ring itself is incredibly lightweight and comfortable—you quickly forget you’re even wearing it. The sizing kit made the process simple and ensured a perfect fit before purchasing, which we really appreciated. What truly sets this ring apart is the level of insight it provides. The sleep, activity, and recovery data are detailed, easy to understand, and genuinely useful. In our personal experience, the readiness and cycle insights were incredibly accurate—so much so that the data suggested something was changing before doctors were able to confirm my wife’s pregnancy. While this is obviously not a medical device, it was impressive to see how closely the trends aligned with real life. Battery life has been excellent, lasting several days on a single charge, and charging is quick and convenient. The ring feels well‑built and premium, and the app presents everything in a clear, non‑overwhelming way that actually helps you make better decisions. Overall, the Oura Ring 4 delivers powerful health insights in a sleek, minimalist form factor. It’s perfect for anyone who wants meaningful wellness tracking without wearing a bulky device. Highly recommended.

This is actually my second Oura Ring, the first one was lost, and I liked it enough to buy another. The sleep tracking, recovery insights, and overall health data are excellent and have helped me make better decisions about my sleep and daily habits. The reason I’m giving it 4 stars instead of 5 is that the ring is larger and bulkier than I expected, and it scratches quite easily during normal everyday wear. The scratches become noticeable pretty quickly, especially if you’re active or work with your hands. I also wish Oura offered a trade-in or upgrade program. As new generations are released, it would be great to have an option to trade in older rings for credit toward a new one. Even with those downsides, I still think it’s one of the best health-tracking wearables available. The fact that I bought a second one after losing my first says a lot about how much value I get from 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?

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.

The Oura Ring 4 blends sleek design with powerful health tracking, offering detailed insights into sleep, activity, and recovery. It’s comfortable for daily wear and boasts long battery life, but its high price and required subscription may not suit every budget. Overall, it’s a premium, reliable wellness companion.

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!

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!

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.

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.

"I've been using the Oura Ring 4 for a few weeks now and it has completely changed how I track my health. Unlike a smartwatch, it's barely noticeable on your finger — looks just like a regular ring. The sleep tracking is incredibly detailed and accurate; I wake up knowing exactly how restorative my night was. Heart rate, HRV, SpO2, and temperature monitoring all work seamlessly in the background without me having to think about it. The Stealth finish looks clean and premium. Battery lasts me about 6–7 days on a single charge, which is impressive for how much it's doing. The Oura app is well-designed and the insights actually feel actionable. Size 13 fits perfectly — glad I used the sizing kit before ordering. Well worth the investment for anyone serious about their health data.

I cannot rave enough about how much I love this ring. Many people have seen it on my finger and asked how well it works and I always have great things to say about it. First off I will say that the sizing kit that you receive prior to the ring is really accurate. The actual ring fit just as the sizing ring did. The ring looks thick, but it is actually very comfortable and I even forget it's on my finger sometimes. That is a huge bonus that I was not expecting. I went with the rose gold color and I love it! I love that the ring fits perfectly snug on my index finger but it also fits on my middle finger. I can switch it if for any reason it starts to bug me on my index finger, but so far I have not had that problem after wearing it for over a week. It only took about 45 minutes to charge and lasts me 7 days. I love that you will get a warning to charge it later in the day before bed time when the battery is low. The app has some great features and tells you about your sleep regimen, how long you are in REM sleep, how long it takes until you fall asleep, deep sleep time and more. It scores the different features and tells you what those scores mean and ways to improve. It also tracks your activity and how many calories you are burning, your heart rate during all periods. It measures your stress level based on the other activities and your body temperature throughout the day. This is such a great ring and the best part about it is you don't have to take it off except when you need to charge it (45minutes give or take) every week. It's very comfortable to wear and comes in different colors. It can be submerged in water so you can wear it while you shower or if you go swimming. Just make sure it does not get loose when you are in water if, like me, you do not like to wear tight rings but a semi snug fit works better. I have worn it while washing dishes, showering, doing yard work and many other activities. The ring color still looks great and its very easy to wipe and clean with a dry cloth. I would def recommend this ring to everyone. It is so useful and gives such great information. The longer you have the ring, the more information can be measured over a longer period of time.

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.

Works exactly as expected. Comfortable, accurate tracking, and battery lasts a long time. Easy to use and looks clean. Definitely recommend.

I have had my ring for about 6-7 months now and can say that I don’t have many complaints. There’s so many good things about the ring, a few major things I like are tracking sleep, the battery time and how quick it charges. There’s so many other things it tracks that help too. Also the water resistance is amazing. A downside is that they scratch pretty easy from ware and tare. Other than a few small things I have nothing bad to say about it.

The Oura Ring has been a great addition to my daily routine. The sleep tracking is incredibly accurate, and the insights on readiness and recovery feel more meaningful than what I’ve seen from typical smartwatches. I like that it’s lightweight, comfortable, and easy to forget I’m even wearing it. Battery life is solid—usually around 4–5 days per charge. The app is clean and easy to navigate, with helpful recommendations based on my activity and sleep patterns. I’m genuinely impressed with the Oura Ring. The sleep analysis is on another level—tracking deep sleep, REM, heart rate variability, and even nighttime movement with surprising accuracy. The readiness score has helped me adjust my workouts and daily habits, and I’ve noticed real improvements in my energy levels. The ring itself is sleek, durable, and comfortable enough to wear 24/7. Battery life is excellent, and the charging dock is simple and fast. Yes, there’s a monthly membership, but the insights feel personalized and actionable, not just generic data. For anyone focused on health, recovery, and sleep optimization, this is a fantastic investment. Excellent health tracker. The Oura Ring gives detailed sleep insights, accurate heart-rate tracking, and great battery life. Super comfortable and much less intrusive than a smartwatch. The subscription isn’t ideal, but the data quality makes it worth it.

I’m very happy with this ring. The quality feels excellent, it looks exactly like the pictures, and it’s very comfortable to wear all day. The design is sleek and modern, and the fit is perfect. Battery life has been great so far and it works exactly as expected. I would definitely recommend it to anyone looking for a stylish and reliable ring.
