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.

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!

Rapid, efficient and friendly customer service! So refreshing...
Purchased ring 11/2024. Worked very well until recently, when the battery would not keep a charge, even overnight. On a whim, I contacted customer support via an online chat. Diagnostics on my ring indicated a battery issue. Even though it's out of warranty, they are replacing it at no cost. Couldn't be more impressed by the rapid response and very user-friendly interaction.

Love it!
I love this ring. I bought this for my husband since I already have one and he’s loving it so far too. It really helps see a picture of health markers that aren’t tracked as often. I tried knock off brands and although cheaper, you get what you pay for and they were unreliable and inaccurate. Oura is always on point and accurate. It’s worth the investment for me since health is so important to me. It broke my heart to watch my mother succumb to illnesses and disease that could have been prevented if she had just taken the steps to monitor sooner. This is a tool we use in addition to diet and lifestyle. I highly recommend.

Helpful Health Tracking, Not the Most Comfortable Fit
I’ve only had the Oura Ring for about a week, so I’m still learning the app and how the data works. Some of the data doesn’t always seem accurate yet, but I understand the ring needs a few weeks to collect enough information and adapt to your body and daily activities. Because of that, I’m reserving final judgment until I’ve used it longer. That said, I really like how it tracks sleep. It’s interesting to see how long I spend in each sleep stage, and I appreciate the insights it provides. I also like the heart rate and blood oxygen tracking. There are options to add and track more metrics, but I haven’t gone that deep into the app yet. One thing I don’t like is that workouts have to be manually entered. Right now, I’m logging my exercises myself, and I’m not sure if this improves after the ring gathers more data over time. Calorie counts also don’t always feel accurate. Additionally, the ring sometimes records a nap when I’m just resting in my recliner watching TV, which may be because it’s still early in the adjustment period. Another downside is the fit. The ring is bulky and doesn’t feel like a regular ring. My normal ring size is 10, but it wouldn’t get past my knuckles. Size 11 felt too tight after a while, and since there are no half sizes, I went with a 12, which is slightly loose. I usually wear it on my right index or middle finger, but on days when my fingers swell, I have to switch fingers because the thickness can make it uncomfortable. I’m still early in using it and hoping this improves as I get used to it. Overall, I think the Oura Ring has potential, especially for sleep and health tracking, but since I’m still in the early stages, I’ll need more time to see how accurate and comfortable it truly becomes.

I’ve only used it for a week so I haven’t gotten the full insights it can offer, but the Oura ring 4 has been great so far. I bought it primarily to track my sleep, and it’s fascinating to track the quality of my sleep each night.

Der Ring war ein Geschenk für meine Frau und er ist sehr gut angekommen. Sie checkt jetzt täglich Schlaf- und Gesundheitswerte und lässt sich von der zugehörigen App motivieren. Der Ring macht einen hochwertigen Eindruck, ist sehr leicht und hat eine lange Batterielaufzeit. Wer also seine Gesundheits- und Fitnesswerte sehr genau tracken will, aber keine Fitness-Watch haben möchte, ist mit dem Oura-Ring sehr gut bedient. Nicht ganz so schön ist das monatliche Abo, das aber deutlichen Mehrwert bringt. Tipp: vorab das Größenbestimmungs-Set für € 10 kaufen - der Betrag wird beim Kauf des Rings angerechnet.
