I’ve been using my Oura Ring for a month now, and I’m genuinely impressed. It’s sleek, lightweight, and easy to forget you’re even wearing it which is exactly what I wanted in a wellness tracker. The sleep tracking is incredibly detailed and has helped me better understand my sleep patterns. I’ve started making small changes to my routine based on my readiness scores and have noticed a real difference in my energy levels. I also appreciate the insights on recovery, heart rate, and activity without the bulk of a smartwatch. The app is user-friendly and the daily reports feel like a personal check-in. The only thing to note is that sizing can be a bit tricky – I used the sizing kit before ordering and I’m glad I did. Battery life has also been solid; I only charge it every 3-4 days. Overall, this has been a great investment in my health and well-being. If you’re looking for something subtle, smart, and science-backed, I highly recommend it.

The ring fits on my right pointer finger just fine. That finger, for whatever reason, is wider than my left finger but it still fits well. After sleeping through the night, it’s a bit more snug. The information the Öura Ring provides through the app is helpful as I’m an extremely light sleeper. It has helped me understand my sleeping patterns and has predicted my cycle perfectly twice now. It records exercise/activity better than my Gen 8 Apple Watch but I’m not really comparing the two too much. It does have some light scratches but that’s to be expected when wearing it all day. The battery is at 88% after a full days use and I typically charge it in the shower. I would recommend this to someone who is looking for health and wellness details for themselves as the Ring really does provide great detail.

Oura is just what I’ve been looking for in a fitness device—and a lot more. Have been frustrated with previous fitness bands, not very accurate, tiny screens, and need to remove whenever around water. I wasn’t looking for a device that beeps, buzzes, notifies me of calls, emails, etc. Just wanted a reliable , easy to use accurate one. Oura provides tons of data, including basic vitals, steps, detailed sleep analysis , stress levels, and lots of suggestions on how to improve health. It’s waterproof, so I never have to take it off to shower or do dishes. It’s comfortable to wear, and all the data is only available to view on your cell phone, where it’s easy to read. I haven’t yet tried all the great features, including calorie counting. So much to see and learn. I have to charge it about every 4-5 days, not a week as advertised. Charging is fast and easy. Highly recommend!

Let me start by saying I REALLY wanted to like this ring! I wouldn’t have spent so much money on it if I wasn’t all in! My first disappointment came from, just learning/realizing that the ring did not have the functionality that, I had understood it to have. Does it track your heart rate? Mmmmm… sort of. If you are hoping for it to track your heart rate while you are exercising, you are going to be sorely disappointed. It does heart rate readings every 10 to 30 minutes. No matter what you’re doing. That is one reading every 10 to 30 minutes… Which by the way you have no control of so it might be 10, it might be . So if you’re hoping to capture your peak heart rate while you are exercising, good luck. There is a function where you can record your workout and, I thought maybe that would be a workaround but no, all that really does is, record your path with GPS tracking to give you a visual of the route you took. And it’ll take a couple heart rate readings but, again, not at any meaningful regular interval while you are exercising. There is a manual function to check your heart rate which, has to be selected in the app and then it asks you to stay still for 30 seconds so that it can take your heart rate… And again, if you’re exercising, and you want your heart rate being tracked, you can’t stop everything and pull out your phone every few minutes to force it to take a reading. And, don’t forget, to also stop and be still so that it can take the reading.🤦♀️ Does it detect when you are stressed? One of the features this ring boasts is, tracking your stress. Supposedly, your body gives off particular signals when you are stressed and, the App puts a lot of focus on the amount of stress that you’ve had during your day. The problem is, it’s wildly inaccurate. It goes further to say that, eating, exercising, or doing things you enjoy can all give off those same signals as stress lol so, it’s not really a very useful metric for anything IMO. It will say I am stressed when I am eating, when I am exercising, but even when I am doing something relaxing and enjoyable like, in my garden interestingly enough, it has correctly detected a few times that I got particular news that sent my stress levels way up. It did pick those up. But, again, how useful is it if, it picks up so much of everything else as stress also 😆 I mean unless you are just a slug and lay around all day, it’s going to report that you had stress throughout the day 🤷♀️ And how about that subscription? Does the ring give basic metrics without the subscription? No. Big fat no. This is my biggest problem with this ring. I didn’t know if I felt like that the subscription would be valuable enough to me so I made sure before I purchased it that, if I didn’t want the extras of the subscription that the ring would still continue to track the most basic things like, step count. And, it reports that it does do that. HOWEVER, what they fail to mention is that, they don’t make that data available for you to see anywhere anymore lol and, it no longer updates Apple health or whatever other app you are integrating in with. So, it does NOTHING without the subscription. The only thing it will do is give you these silly readiness scores for your day. If it feels like you got a good nights sleep then it will give you a good readiness score for the day and a good sleep score. But you will see absolutely none of the data that went into building that score. No more steps, no more heart rate, no more anything. That’s IT. You can buy a ring for a fraction of the price that gives you all way more functionality, WITHOUT a Subscription. The way they make it sound before you purchase is that the subscription gives you a lot of extras. And I was willing to pay that if I felt like those extras were really valuable but because the data is so wildly inaccurate, I didn’t feel like it was particularly valuable what I thought I was getting as an “extra” From the subscription. Had I known it wouldn’t do the most basic thing to count steps without a subscription, and actually show them to me either in the app or by writing them to Apple health, I would have never purchased this ring. You’ve been warned! Good luck!

I recently purchased the Oura Ring 4 in silver (size 6), both for myself and my wife, and overall, we're really impressed. The sleep tracking is fantastic! It's been incredibly insightful to see our sleep patterns and get data on our heart rate and activity levels. The ring itself is sleek and comfortable to wear, and the battery life is truly impressive – lasting nearly a week. However, there's one major downside: the subscription fee. For a device that's already quite expensive, adding a monthly subscription feels unnecessary and a bit greedy. While the data it provides is valuable, I wish they would offer a one-time purchase option or a more affordable subscription plan. Despite the subscription issue, the Oura Ring 4 is a great device for tracking sleep and general wellness. 1 If you can stomach the ongoing cost, it's definitely worth considering.
