Great for sleep and recovery tracking without wearing a bulky watch
Style: Ceramic Color: Cloud Size: 9

I’ve really enjoyed using this ring so far. It has a good lightweight fit, comfortable, and much less distracting than wearing a smartwatch all day and night. Great functions including sleep tracking which has been especially helpful and honestly feels pretty accurate compared to how rested I actually feel. The app is clean and easy to understand but it is not included and you have to pay a monthly subscription. I like being able to see trends with sleep, stress, activity, and recovery all in one place. Very duarable. The ceramic cloud color also looks sleek and neutral enough to wear with everything. Battery life has been solid too. Expensive, yes, but if you’re into health tracking and want something more minimal than a watch, I think it’s worth it. ... show more

A Wellness Game Changer That Helps Me Understand My Body
The Oura Ring 4 has truly been a game changer for me! As someone living with chronic illnesses, being able to better understand my body, track my patterns, and recognize changes has been incredibly valuable. This ring gives me insight into things like sleep, recovery, readiness, activity, and so much more, helping me become more in tune with what my body needs. I was a little hesitant about the price and the monthly subscription at first, but after using it, I can confidently say it’s worth the investment. The amount of information and features it provides makes it feel like a personal wellness tool right on my finger. I love that it helps me notice trends, make better decisions for my health, and understand when I may need to slow down or prioritize rest. If you’re someone who wants to be more connected with your body and your overall wellness, the Oura Ring 4 is definitely worth considering. This has become an essential part of my daily routine, and I couldn’t recommend it more! ... show more

Love my OURA!!
Style: Ceramic Color: Cloud Size: 8
The OURA ring 4 is absolutely awesome! I bought it in the ceramic cloud white color and couldn’t be happier. First off, I love the aesthetic and it just looks cool. Second of all, the app is excellent and gives so many different health matrix that you can find just about anything you’re looking for. It’s comfortable to wear during exercise and while you’re sleeping. I love that I can go multiple days without charging it. I barely notice that I’m wearing it most of the time. I bought it during prime days, so I got it on sale and feel like it was definitely worth the price. ... show more

I love my Oura ring! The first few weeks I was obsessed with it and the app but now I forget it’s even there but still worth it. I got it on prime day so the price was great for the time!

Review Image by Mary
I've had my Oura Ring for about four months now and wear it 24/7. I appreciate the data on sleep and activity. The data seems more accurate than my Apple Watch. The battery life is about 5 days. The ring itself has no scratches or dings even though I wear it while working out, cleaning, cooking, and other daily activities. The app is stellar with lots of features that you can choose to use to track a lot of health indicators. I'm a big fan of this little wearable. ... show more

It's honestly a bit better than I was expecting.
Style: Ceramic Color: Cloud Size: 9
I'm very happy so far with this purchase: I've been wearing it now for about six weeks, and I'm starting to become very familiar with most of its intuitive projections. I've been sick recently so I did put the data on "rest mode" so I'm not given an activity goal, but the other data that drips in is quite helpful. I still wear my Garmin watch because I do need something to tell me the time, but the Oura provides a level of data that the Garmin hasn't been able to touch in their updates, and I like the Oura's interface and app much better. I ordered the sizing kit but never received the $10 credit once I ordered the ring itself, so that was a bit of a let-down, but the sizing was spot-on to the sizing kit, NOT to my actual ring size. I garden like a maniac and although I thought the ring was scuffed up in quite a few places, after a good wash, it's back to perfect. It stinks that the ceramic costs so much more but I do believe it would be the better choice for a coating over the long run. The color is fantastic as well, I'm really happy I went with it. The ring is durable: it is thick on my left index finger, but I stopped noticing it after day 3 or so. My only recommendation is that if losing weight is your primary focus and if you are torn between two sizes, I would size down. You really can shuffle to a different finger if you need to, but I do believe that with the toning up I've done, I could have gone down and it would have been a better, solid fit for the new version of me. Battery life could be better, but after owning an Apple Watch for a few years, I'm not sure what the complaints are because it's nowhere near as bad as that. I'm having to charge every 5 days or so, but I just throw it on the charging plate while I'm showering and it's ready to go after. I do wear mine 24/7, so YMMV on battery. Overall, I've gone from a TomTom watch to a Fitbit, to Apple, another Fitbit, another Apple, a few Garmins, but I do like the Oura the best. I have no experience yet with customer service, but I'll update if I never need to. ... show more

Full of data while compact
Style: Ceramic Color: Midnight Size: 10
I’ve been extremely impressed with my Oura Ring. I love how much it tracks—from stress levels and cardiovascular metrics to personalized AI insights that actually help me understand my health trends over time. The information feels tailored to me rather than just presenting raw data, which makes it much more useful. I also chose the darker finish and was worried it would scratch easily, but it’s held up much better than I expected. It still looks great after regular daily wear. One unexpected benefit is how much I enjoy not having constant notifications on my wrist. I’m honestly considering replacing my Apple Watch with the Oura Ring full-time because it gives me the health data I care about without all the distractions. If you’re looking for a sleek, comfortable health tracker, I’d definitely recommend it. ... show more
