Customer Ratings & Reviews

Works great.Works well for tracking your workout and sleep. Baterry last for 5 to 6 days.

I absolutely love my Oura Ring Gen 4, it’s hands-down one of the best purchases I’ve made for my health and wellness. I originally got it to track my sleep more accurately, and it has completely delivered on that promise (and then some). The sleep tracking is incredibly detailed—far beyond what I’ve seen in other devices. I get real-time insights into my sleep stages, restfulness, heart rate variability, body temperature, and even readiness scores that help me understand how well I recovered overnight. It’s amazing to wake up, check the app, and have a clear picture of how I slept, not just how long I was in bed. Beyond sleep, the Oura Ring also tracks activity, recovery, stress signals, and daily movement, all in a way that feels personalized and intuitive. And because it’s a ring, it’s lightweight, discreet, and comfortable—I forget I’m even wearing it. The battery life is great too; I typically get several days on a single charge. If you’re someone who values sleep quality, daily readiness, or just loves seeing detailed health metrics without wearing a bulky watch, I highly recommend the Oura Ring 4. It’s more than just a tracker—it’s a powerful tool for optimizing how you live and rest.

After three weeks of wearing an Oura Stealth on my index finger, I think until and unless Oura offers half sizes, this device should not be considered a “wearable” for many of us. I went to Best Buy to use their sizing kits and take advantage of helpful humans and same-day purchase. I was planning a trip in three weeks and wanted to test the ring’s ability to track health during travel. I found a Best Buy expert who said index is the preferred finger. A 9 was a bit tight but she said previous Oura owners were dissatisfied with results from other than a snug fit. I bought it. A week later I asked Oura Customer Service about the slight depression on my index finger and whether a ring finger is acceptable. Two days later I received a glorified AI FAQ (or rather, “FAQ off”) email with a name at the bottom to make you think a human actually spent time on it. “Naomi” said only that index is preferred and there are no half-sizes. In effect, suck it up. Even so I went back to Best Buy to size the ring finger and found a slightly better fit, but Best Buy did not have it in stock. With only a few days left before departure I decided not to risk mail order. Big mistake. I learned that fingers swell quite a lot during air travel. At some point I noticed the ring was chafing painfully. I put some soap on it to get it over the knuckle and applied it to the ring finger, where it now fit pretty well. The ring finger test lasted two days. It was looser fit and did not pick up data near as well as the index. At some point I looked down to see the ring was gone. Whether at a luggage carousel or washroom I don’t know. But good riddance. The ring was nice looking though not as sleek as my wedding band; worn on the dominant index finger it interferes a bit with pens and forks, but on the other hand it interferes unacceptably with fretting a guitar. I didn’t like the app. I wanted to check it upon waking to see how sleep went, and review activities from the previous day. Data download data from the ring takes long—OK, a tradeoff for small size and longer battery life, live with that. Pressing the top-tab for “Yesterday” takes me to a calendar from which I can select yesterday and see… today’s scores again. After fussing about in the menus I manage to find yesterday’s data curves but I’m still not sure how I got there, perhaps it just takes time for the app to retrieve the saved data from a server somewhere. Activity tracking is not intuitive. The app guesses your activity and asks you to confirm. Guesses well for playing guitar or walking—stationary bike not so well, I think because the accelerometer is not as engaged. The ring has only this, ten-minute interval heart rates, SpO2 readings and time of day as inputs, and uses some algorithms to interpolate from that. You can change the app’s guess about your activity by selecting from a list with “choices” including Finnish baseball but not, oddly enough, sex or sauna. I tried to use “Tags” feature as a workaround but the entry screen is unhelpful. I can choose Start and End times, but cannot compare to detailed heart rate graphs to refine when those happened. It takes three passes to save all three Tag data points. I got little from the analyses. It was told when I got to sleep late—I knew that without the app—but no advice on why REM and Deep sleep are consistently red, though I felt rested. (One poster on internet said he fixed his low scores but getting a different ring!) I saw interruptions in SpO2 that might mean sleep apnea—or one of five other things, like a poorly-fitting ring. I saw no info on stress levels (yet). I was consistently low on heart rate variability, which is supposedly a bad thing, but I felt fine. Maybe the ring needed more time to adjust to my personality. I was hoping to see if I needed the extra analysis provided by the add-on $5/month subscription but never did understand what was covered and what not. I see from Oura-sponsored research that Oura does a 5% better job at detecting sleep levels than other wearables; but none are as good as EEGs. Bottom line: expensive with hidden fees. If a perfect fit, it might work for you. Otherwise, until and unless Oura makes half sizes for the rest of us, their rings cannot really be considered “wearables.” Watch formats work as well for less money.

I initially ordered the size 9 for my left index finger, but after a week I realized it slipped off every time I washed my hands. I switched to a size 8, which fits perfectly. The gold color is beautiful, though it can look slightly orangey in certain lighting. The health insights and data it provides are excellent and have already helped me be more aware of my activity and sleep. I do wish it connected more seamlessly to third-party apps like Glow or Garmin Connect. Battery life is impressive — I get about a week on a single charge. After several weeks of daily wear, I’ve had no scratches, even with workouts and handwashing. It is a bit wide for my taste since I usually wear minimalist jewelry, but it’s still very comfortable and I barely notice it on. I’ve had it for less than a month, so I’ll need more time to give a final verdict, but so far it’s been a great addition to my wellness routine.

I'll start by saying I've been wearing an Oura ring for about 5 years. I got the OG ring with the flat side. I had the Gen 3 previously and it worked well for me, I even got a replacement from Oura when the battery started to give out. After 2 years or so, I decided I wanted to upgrade to the Ring 4. I got the sizing kit since I hadn't worn a ring without the protruding sensors before. Originally I wore a 6 for the OG and it was a bit loose. For the Gen 3, it felt more snug. When trialing the Ring 4, I got a 6 again after wearing the sizing kit since Size 5 felt too tight for my pointer finger and OK on my middle finger. I previously could wear my Gen 3 on my ring and middle interchangeably and on either hand. My dilemma was I wanted the flexibility, but for this ring, 6 was too big and 5 was too snug. Ultimately after wearing both, I opted for the Size 5 and only wear on my middle finger. It was disappointing because I sometimes like I wear other rings and move my Oura ring to my pointer finger so it doesn't scratch, but I will just have to switch it up. For me, sizing down was best and I had to forgo flexibility because I was more worried about my ring sliding off. Otherwise, good build, I like how sleek it is, and though sizing is a pain I like the flat sensors, it doesn't leave marks or dig into my finger.

Great product overall! I’ve had step trackers for a long time, but this one goes beyond, especially software wise. I think it is pretty accurate and learns your behaviors for even better future accuracy. And it looks great. I will definitely stay with this and future variants.

I like that I don’t have to charge it every night. I bought it to help keep track of my menstrual cycle and stress levels. Data has been pretty accurate so far.

Love this ring. It's so much better than a smart watch. Way less noticable and blends more with everyday outfits

I’ve been using the Oura ring for a while now and I can confidently say it’s one of the best investments I’ve made for my health. It comfortable enough to wear all the time and it blends in easily to my daily life. I only have to charge it once a week for about an hour.

Seems to track accurately, comparable to my apple watch. Realistic battery life has been averaging around 4.5-5 days between charges.

Love this ! I liked buying from best buy because they have a display with all the ring sizes . I researched this ring a long time - I was reluctant to buy this one because of the subscription but it’s worth the money - love how it records my life events stress and sleep . Great it knows my workouts and works well with my Apple Watch . I recommend highly. I have the silver and amazingly after a month no scratches

The main purpose for this purchase was to monitor my sleep. This ring does a very good job of monitoring various aspects of my health - in addition to sleep, activity, readiness for the day, stress level, heart rate, etc. I prefer it to a clunky watch. It's comfortable and I'm very pleased with the purchase.

I was skeptical before I purchased, but did the research and bought the ring. I am very happy with my decision! It complements my watch in tracking my sleep, workouts, stress levels and glucose. It has helped me make some adjustments and to regulate some habits better. Great ring, unobtrusive and beneficial!

Excellent device - The stats are great to see and has helped me a lot with my sleep schedule. I can compare what I did on certain days that helped me get higher sleep scores. I can also compare it on nights I get terrible sleep and see what may have caused that. Overall its fantastic.

Best tracker ever I love it it’s so accurate, love the app, battery lasts forever

I love this ring. I have had Apple Watches for years but got tired of not being able to wear different watches while still tracking health metrics. This is a great alternative that is stylish, accurate and the battery lasts a long time. I also like that I don't have to have another screen on my wrist and always getting notifications on another device.

The Oura Ring 4 has completely changed how I understand my sleep and recovery. It’s incredibly comfortable — I forget I’m wearing it — yet it delivers detailed sleep staging, readiness scores, HRV, heart rate, and activity tracking that actually help me adjust my habits. The battery lasts nearly a week, the design is sleek and lightweight, and the insights in the app are clear and actionable. I’ve improved my sleep routine just by following the trends it shows me. Yes, there’s a subscription for full features, but for the depth of sleep and recovery data you get, it’s absolutely worth it. If you care about better sleep, smarter recovery, and a wearable that doesn’t get in the way, this is it.

Best finish and fit for comfort. Helps me know what my sleep looks like everyday.

I love this ring! This is a great, low profile alternative to my Apple Watch - I was interested in moving away from the workout-focused watch metrics and into something more holistically body-focused, and this ring is perfect for that.

I love this ring! It’s very comfortable and very useful, it helps me a lot with my anxiety and sleep problems, it even tells me when I’m about to get sick!!
