Oura Ring 4 Sizing Kit - Size Before You Buy The Oura Ring 4 - Unique Sizing, Not Standard US Ring Sizes - Receive Credit for Purchase

I absolutely love this ring and all it offers. I’ve recommended it to everyone who has asked about it in the 11 months I’ve been wearing it (24/7). I know at least one person who has purchased one based off of my recommendation. Lately, within just the last few weeks, I’ve noticed the battery life has decreased sufficiently. Going from 5-6 days between charges to 2-3 days. Then the last week, I’ve begun having connectivity issues. While frustrating, I love this ring. So much so that I was seriously considering buying another one. But that $400.00 price tag is steep. Today I decided to submit a question for help through the app. Within 5 minutes tops, the virtual assistant determined I was indeed having issues, confirmed the ring I have is in stock and informed me that a replacement would be shipped with arrival time at 1-2 weeks. I am just under the year (purchased 4/8/2025 and today is 3/4/2026) but that was unexpected and honestly, amazing!!! I am so impressed. Enough so, I came to Amazon to write a review (which I never do). I will continue to recommend this product to anyone and everyone who asks!!!

I work out 5 days a week, and my Oura Ring Gen 4 has been an absolute game-changer for my routine and recovery. The sleep tracking alone has helped me understand how my body actually recovers, not just how hard I train. Seeing my sleep quality, readiness, and recovery metrics every morning has completely changed how I plan my workouts. What really stands out is how seamlessly it tracks my overall wellbeing—from sleep stages and recovery to daily readiness and trends over time. It’s helped me dial in better habits, know when to push hard, and when to prioritize rest. The insights feel meaningful and actionable, not just data for data’s sake. On top of that, it’s comfortable, unobtrusive, and easy to wear 24/7. The battery life is great, it runs easily for about 6-7 days with one full charge, plus it charges pretty quickly. If you’re serious about training, recovery, and long-term health, this ring is 100% worth it. I honestly can’t imagine my routine without it now. 💪

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.

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!

Definitely get the sizing kit before you buy it. After having it for many months, I can say with certainty that this thing RULES! Life changer. A few more things quick...first, I got the brushed stainless finish. Its beautiful and gets more beautiful as it ages, scratches and gets more and more beat up. Yes, I said MORE beautiful as it gets worn. So dont be afraid to wear it. Im a mechanic and its held strong. Second, I like wearing REAL watches. Not smart watches. This allows me to wear "real" watches and also have all the same functions a "smart watch" has, but on my finger. The app is wonderful. It costs money but its always being updated and its a legitimate health tracker. Ill gladly pay monthly if the developers keep making these great updates. I super duper recommend! Also, if you have and HSA, you can use it to purchase this. If that's something you're in to.

This has transformed how I view and evaluate my personal health. I love the form factor - I rarely notice its presence, and it lets me wear a regular watch instead of having to always sport around a smartwatch. Battery life was great when I first got it, but after less than a year it only lasts about a day and a half. I like the stealth finish, but BE WARNED: the DLC coating WILL scratch the life out of any glossy surface you use - including your phone screen. ESPECIALLY your phone screen. Wearing this and carrying a phone without a screen protector is a recipe for disaster. Setup was effortless, despite receiving a previously-paired (used) item. The factory reset was easy enough but I wish I had known ahead of time that I was receiving a used product. As I mentioned, the battery longevity leaves quite a bit to be desired. Brand new, I could easily get a week out of it. 10 months later? recharge notifications every other day. Fortunately, all I had to do was go to the AI chatbot on Oura's site, tell it my ring battery sucked, and it pulled the battery health from my account logs. It saw that the battery was draining fast and immediately asked for my address for the replacement. Didn't have to talk to a single person. So big kudos for that. Also, this WILL 100% guaranteed get scratched, no matter what finish you end up with. In reality, the first few scratches will bother you because it's your shiny new expensive health toy, but after a few weeks you stop caring. even scratched to the heavens and back, it doesn't look terrible. One other benefit to note - recently the news has had increasing reports of smart ring batteries swelling while the user is wearing it, getting it stuck on their finger. The Oura Ring does NOT seem to have that problem. All of the affected units used plastic or epoxy inner rings, allowing the battery to breach the ring. Both the inner and outer rings of the Oura Ring are titanium; there is a gasket fitting between the segments that allows the battery to vent in case of failure, but it should not be possible for the battery to exert enough pressure on the titanium inner ring to get it stuck on your finger in a catastrophic failure mode. Overall functionality: +4/5 Subscription: -1/5 Battery degradation: -3/5 Warranty Support: +3/5 Wont destroy my finger: +1/5

I got this Oura ring for my wife for Christmas this past year and she loves it as well as the rose gold color. It's a very good way to take control of your sleep and improve sleep quality. The ring tracks your sleep down to the minute, is crazy accurate, and works with an app that, once installed, works offline and connects to the ring through Bluetooth. Every morning you can get a full breakdown on the app of your sleep pattern for the night including sleep stages (light, REM, deep), heart rate, heart rate variability, body temperature, respiratory rate, total sleep vs time in bed, your sleep efficiency, your "body clock" and even "sleep debt" (which tracks how much sleep you're getting vs how much you need for your body type). It also tracks the menstrual cycle for women, which my wife uses and likes a lot. She's been able to figure out a pattern based on her heart rate that happens the day before her period actually starts, which works every time - super cool! Of course it does other things like tracks your steps, exercise, you can log your meals etc. Too many things for me to include in this review. The ring fits my wife's finger perfectly. Before you buy you have to purchase the ring sizing kit, which is cheap, and you can use it for friends if you refer people (which you can get awarded for monetarily). The sizing is pretty easy, wear one of the sizers for a day and make sure it's comfortable and then order your ring. I've also seen the ring sizing kits on display in places like Costco or Best Buy, so that's another option without having to buy the kit. The battery lasts about a week, which is pretty good. And it charges in less than an hour, sometimes half an hour if she's charging it more regularly than a week (which your supposed to do). My own Oura Ring 4 is over a year old and I have to charge it every 2-3 days. I admit, I did not follow their recommendations for maintaining the best battery life, so can't complain there. Overall, Oura Ring is fantastic and I'd highly recommend it to anyone. My wife and I have both been able to improve our overall sleep quality since using them. They are a very good tool for that if you want to prioritize sleep in relation to health (which anyone should).

Getting an Oura Ring has honestly been one of the most helpful tools in my health journey. Instead of going into appointments trying to explain symptoms from memory, I now have clear, daily data showing my heart rate trends, sleep disruptions, and recovery patterns. Because of the consistent tracking, I was able to show my doctor objective patterns rather than just saying “I feel off” or “my heart feels different.” The data helped validate what I was experiencing, which ultimately contributed to receiving an actual diagnosis instead of being dismissed. That alone made it worth it. It’s especially helpful seeing nighttime heart rate, HRV, and how my body responds on days when my symptoms flare. Having that timeline has made conversations with my care team more productive and taken a lot of the guesswork out of my treatment discussions. More than anything, it’s given me a sense of control during a really overwhelming health season. Instead of feeling in the dark, I can advocate for myself with real information — and that has helped guide a more informed, personalized plan toward my treatment and recovery.
