Excellent Smart Ring – Highly Recommend!
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I recently purchased the Oura Ring 4 in black, size 9, and I couldn’t be happier with my experience.

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.

Powerful little ring!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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!

Happily Married to my Health
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.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.

Oura Ring comfortable and NOT bulky
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.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.

Small Ring, Powerful Health
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Oura Ring Gen 4 (Black) is one of the most impressive wellness devices I’ve used. It delivers deep health insights in a sleek, lightweight design that you forget you’re even wearing. Unlike bulky watches, it’s comfortable enough for 24/7 use—especially during sleep, where it truly shines. Sleep tracking is incredibly detailed and accurate, breaking down sleep stages, recovery, readiness, and trends in a way that’s easy to understand and actually useful. The daily readiness score helps me decide when to push hard or prioritize recovery, which has been a game changer for energy and consistency. I also appreciate the long battery life and premium black finish—it looks modern, minimal, and works with any style. The app is intuitive, well-designed, and constantly evolving with meaningful updates rather than gimmicks. The only downside is the subscription requirement, but the value of the insights more than makes up for it. If you care about sleep, recovery, and overall health—not just step counts—this ring is worth it. Overall, the Oura Ring Gen 4 is a powerful, discreet health companion and one of the best wellness investments you can make.

Comfortable Health Tracker, Great App
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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?

This Ring Quietly Runs My Life
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I didn’t expect to love a ring this much… and yet here we are. My Oura Ring quietly judges my sleep, cheers me on when I move my body, and gently reminds me that maybe my third cup of coffee at 4pm wasn’t my best decision. It’s like having a tiny wellness coach that lives on my finger and never yells at me. I love how unobtrusive it is—no bulky watch, no buzzing notifications—just clean insights that actually make sense. The readiness score alone has saved me from overdoing it on days when I thought I was fine (spoiler: I was not). Bonus points for the battery life, the sleek design, and the fact that it somehow knows when I’m stressed before I do. A little creepy? Maybe. Incredibly helpful? Absolutely. 10/10 would let this ring continue to monitor my sleep and life choices.

Excellent Health Tracking Without the Distractions
||Posted . Owned for 7 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Oura Ring 4 is genuinely impressive. It delivers deep, accurate health and sleep insights without the constant notifications and distractions of a smartwatch. The data feels meaningful, especially for sleep, recovery, and overall readiness. Comfort is a big win here. After a short adjustment period, you forget you are even wearing it, including during sleep. Battery life is solid, and the app presents information in a clear and actionable way instead of overwhelming you with numbers. This is not a fitness toy. It is a serious health and recovery tool. If you care about understanding your body rather than checking messages on your wrist, this is one of the best wearables you can buy.

Oura Ring 4 — The Wearable You Forget You're Weari
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.As someone who struggles with bulky fitness trackers and watches, the Oura Ring 4 has been a revelation. Its discreet design and incredible comfort are, without a doubt, its biggest selling points. This is the first health tracker I've truly been able to wear 24/7 without ever feeling like it's getting in the way. The comfort improvements over previous generations are immediately noticeable. Oura flattened the internal sensor bumps on the Gen 4, making the inside of the ring perfectly smooth. This is a game-changer. The ring slips easily over the knuckle and, once on, it feels like a piece of regular jewelry rather than a tech gadget. I've worn it while washing dishes, gardening, typing all day, and, most importantly, sleeping—and I genuinely forget it's there. This seamless wearability is what makes the Oura Ring 4 so effective. Because it never feels cumbersome, there's no motivation loss or decision fatigue about putting it on. It just stays on, collecting highly accurate data on sleep, readiness, and stress without any conscious effort from my side. If you're looking for world-class sleep and recovery tracking without the distraction of a smartwatch, the Oura Ring 4’s elegant design and effortless comfort make it the best wearable choice on the market.

Amazing Smart Ring with Effortless Exchange
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I purchased the Oura Ring 4 in Stealth (2024 model) from Best Buy, and it’s quickly become my favorite health tracker. The titanium build is super comfortable, the recessed sensors make it feel seamless on my finger, and the matte black finish looks incredibly sleek and modern. Sleep tracking, readiness scores, and stress monitoring are incredibly accurate with the new Smart Sensing tech—I’ve noticed real improvements in my routines thanks to the insightful app feedback. Battery life is fantastic, lasting up to 8 days, and the redesigned app is intuitive and motivating. I did end up exchanging for a different size after using the sizing kit (great advice from Oura!), and Best Buy made the process super easy—no hassle, quick in-store exchange, and friendly staff. Caught it on a solid sales price too, making this premium ring an excellent value. If you’re looking for a discreet, high-quality wearable that delivers serious wellness insights, go for the Oura Ring 4. Highly recommend!

What a beautiful way to measure sleep and activity
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.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.

⭐️⭐️⭐️⭐️ Amazing Upgrade — Oura Ring 4 Is Worth Ev
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been using the Oura Ring 4 for a little while now, and I can honestly say it’s the best health and sleep tracker I’ve ever owned. The new sensors are incredibly accurate, and the insights I get every morning actually help me understand how I slept and how to plan my day. The ring is lightweight, comfortable, and way more convenient than wearing a bulky smartwatch 24/7. I barely notice it’s on. The updated design looks sleek and premium, and the battery life is impressive — I can go days without charging it. The app is super clean and easy to use. I love the detailed breakdown of sleep stages, readiness score, and activity tracking. The new features feel more personalized, and the data actually matches how my body feels throughout the day. If you’re on the fence, don’t be. The Oura Ring 4 is absolutely worth it. Perfect for anyone who wants serious health insights without sacrificing comfort or style. 10/10!

10/10 Would Recommend
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Love the Oura Ring. I was hesitant to switch from my Apple Watch, but I am so happy I took the plunge. I don't love the monthly subscription model for the app, but ultimately this is exactly the kind of wearable tech I was looking for. The Oura Ring is discreet, has a great battery life, is comfortable, and gives me all the metrics I need without having constant phone notifications on my arm. Would absolutely recommend this. I also recommend stopping in person by a best buy and using the ring sizer at the store.

A Little Device That Does So Much!
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Oura Ring 4 has been a fascinating addition to my long list of gadgets and technologies. It provides a great deal of insight into my health habits and is especially useful as a sleep tracker. It is very interesting to review your sleep patterns from the night before or previously to see how well you actually slept and what types and amounts of sleep you got. The Oura app is easy to use and functions very well and displays the collected data in very easy to understand ways. The battery life is very good and I usually charge it while getting ready and showering as recommended. This keeps it topped off, but it will last for about a week on a full charge. It is very durable and I’ve had it immersed in both fresh and salt water with no issues at all. The new design with the smaller protrusions for the sensors is very comfortable. All-in-all, it’s a great device and I really enjoy the information that it provides so that I can work to improve my health.
