Review: Happily Suprised - I have had this for a week. It is supposed to track your health better over time as it learns your baseline. However, I am already blown away by this ring. I made the purchase because I have insomnia. I have tried other rings and devices to track my sleep, but they have not worked well. The Oura app is insanly accurate and intuitive. It even clocked that I had trouble breathing one night when I was congested. It can track multiple sleep episodes in one day and naps. It also tracks sleep debt which is very helpful when I am having trouble sleeping. I just had to charge it after a week and I have not taken it off except to shower (you can wear it in shower but I prefer not to get it full of conditioner). Other features have also been helpful like stress monitoring. I am frequently stressed (hence the insomnia) and the ring has clocked that and even has mini relaxing meditations to help me calm down. Literally a game changer. I have tried soooo many alternatives. But this is the one.
Review: Read this review if you are considering the Oura ring! - 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!

### ⭐⭐⭐⭐⭐ Impressive technology in a small, comfortable form factor
*by R***W on January 3, 2026*

We purchased the Oura Oura Ring 4 as a Christmas gift for our 20-year-old son, and it has quickly become one of his favorite gifts. He’s very interested in understanding his body better, and this ring gives him exactly that without being bulky or distracting. The first thing he commented on was how comfortable and lightweight it is. Unlike a smartwatch, he doesn’t feel the need to take it off during the day or while sleeping, which makes it much easier to wear consistently. The sizing kit was definitely helpful, and once the correct size was selected, the fit was spot on. What really stands out is the amount of data and insight the ring provides. He loves being able to monitor things like sleep patterns, activity levels, recovery, and overall wellness in one place. The app presents everything in a clean, easy-to-understand way, making the information useful instead of overwhelming. It’s more about trends and awareness than obsessing over numbers, which I appreciate. Sleep tracking has probably been his favorite feature so far. He’s been genuinely surprised at how detailed the sleep insights are and has already made small adjustments to his routine based on what the ring is showing him. It’s encouraging to see technology used in a way that promotes better habits rather than distractions. Battery life has been solid, and charging is quick and simple. He also likes that it doesn’t constantly buzz or demand attention—it quietly collects data in the background and lets him check it when he wants. Overall, this was a great gift and feels well worth it for someone interested in health, fitness, and self-awareness. If you’re looking for a wearable that focuses more on wellness and less on screens and notifications, the Oura Ring 4 is an excellent option. Our son absolutely loves it, and it’s something he uses every single day.
