Customers say
Customers give positive feedback about the ring’s sleep tracking capabilities, noting it’s better than an Apple Watch, and appreciate its style, particularly the app’s flashy interface. The sizing kit helps avoid guessing the wrong size, and the battery life and functionality receive mixed reviews – while some say it charges for days, others report it stops working properly. The activity tracking accuracy and value for money also get mixed reactions, with some finding it accurate while others disagree, and some considering it worth the money while others find it overpriced.

If you’re into tracking your health – this ring is for you !
I absolutely LOVE my OURA ring , it gives me great insight into my sleep and heart health as well as keeping track of my activity levels and stress levels , it warns me when it senses something wrong & notifies me , as well as , giving me suggestions on how to improve those said things . All and all I highly recommend getting one for yourself . My ring is silver as it goes better with my skin tone & because it’s cheaper 😂 it looks like a normal ring . It fits well , is comfortable , I only take it off to shower or when I’m doing hard work with hands like gardening to prevent it from getting damaged of scratching . The battery lasts a long time, it is very lightweight, pretty self explanatory with set up .

Best purchase!
I’ve been using the Oura Ring for a few months now and it’s truly impressive. The design is sleek and lightweight — I barely notice it on my finger, even when sleeping. What I love most is the accuracy of the sleep and readiness data. It gives a detailed breakdown of deep sleep, REM, and total rest, helping me adjust my bedtime routine and recovery days.The app interface is clean and intuitive, and the daily readiness score really motivates me to listen to my body. I also appreciate that it tracks temperature trends and heart rate variability, which gives a deeper understanding of overall health and stress levels.Battery life is great — I only need to charge it every few days. My only small wish is for a slightly faster charging time and maybe more real-time fitness data during workouts.Overall, it’s perfect for anyone who wants to improve sleep, recovery, and health awareness without wearing a bulky smartwatch. Totally worth it!

Great customer service.
This was a gift for our daughter, after about a year or slightly less, the battery would not last more than a few hours. She contacted the manufacturer and they sent her a brand new one can’t say enough about this company. I can’t speak to what information it collects for you with that’s probably available through the website.

1) Ōura Ring Sizing Kit / 2) Ōura Ring 4 Reviews / 3) Addendum Item
Amazon, despite complaints, views the Ōura Ring Sizing Kit as the same or a similar item as the Ōura Ring 4, itself… thus, two DIFFERENT reviews AND ratings for two COMPLETELY DIFFERENT products.————–1) THE ŌURA RING SIZING KIT / 5-StarsŌura states that the Ring 4 sizes are NOT the same as traditional ring sizes.I did NOT break out my Ring Sizing Loops to determine the veracity of that statement because the cost, of the Ring 4 Sizer, on Amazon is applied as a credit towards the cost of an Ōura Ring 4 WHEN purchased via Amazon.I will say that there is perhaps a little difference, compared to traditional ring sizes, but I’m not sure that it’s much because I ended up with the ring size that I thought would work.Interestingly enough, size 10 that I expected for the middle finger was a perfect fit for the Index finger, which is normally a traditional 9… so there is some difference in the sizing and I wholeheartedly recommend procuring the Ōura Ring 4 Sizer BEFORE purchasing the Ōura Ring 4.NOTE that the Ōura Ring 4 Sizer does not work for all Ōura Ring models, so anyone deciding to purchase a previous iteration of the Ōura Ring, due to cost decrease and/or a Sale, will need to utilize the correct Ōura Ring Sizer for the model ring chosen.If there is a question of Sale or Discount Pricing, due to the delay from checking ring sizes, then I suggest an online Chat with Amazon Customer Service representative to make sure that you can lock in any discounts to use after verifying the correct Ring size.FYI – Ōura recommends wearing the sizing ring on the finger that will bear the ring, in order to become accustomed to the ring size/feel and to see how well it fits throughout a normal day.I followed that advice and I believe that everyone should do the same.—————-2) Ōura Ring 4 / 1-StarFirst, even with the ring sizing kit and wearing the sizer non-stop until the Ring 4 arrived, the size of the Ring 4 in only whole sizes proved inadequate. My hands clearly fluctuate enough in size to be an issue, regardless of the finger or hand that is used.Next, the heart rate (HR) was always available and showing in the app, signifying that the Ring 4 was measuring the HR, HOWEVER, the app called to show the graph of the HR for over two (2) weeks, meaning there was no history nor any assessment available.Next, the Sleep function, even with learning curve, seemed to function out of the box, HOWEVER, after the first recharge of the Ring 4, there was an issue with accurately recording start and stop points of Sleep AND eventually the app would show No Sleep Data AFTER uploading/updating UNTIL THE NEXT day. There was no event showing for sleep ALTHOUGH the Ring 4 clearly annotated the Start of the Sleep period the previous night.Next, even after more than three (3) weeks of use, the app has failed to graph the Blood Oxygen Saturation, in spite of showing the data observed and available to see at any given moment. Again, I find this to be very odd and indisputably useless to the user.Next, the App is full of “flash” or substance but in terms of a quick overall view of all the numbers, like most Apps, no such uncluttered view can be found. While the plethora of information and links is appreciated, the search to locate immediate data numbers across all items is tedious, frustrating and unappreciated.To provide an analogy, it’s like having to read an entire book to search for and locate the Synopsis of the book. For those who aren’t into books, then it’s like watching a TV and THEN SEEING the Preview for the show that you just watched.I and most users seem to prefer a Table of Contents approach where the Raw Data is shown and then you can click to go to the Analysis, Assessment and Suggestions for that particular Biometric.In short, the App’s interface is beautifully flashy and showy but about as useful up front as a Show Pony on a crop farm.That makes it overwhelming, even to those who are focused readers and moreso to the vast majority who are not.Finally, many details and assessments are NOT available for anywhere from four (4) weeks to three (3) or more months.While understandable, it makes it impossible to fully assess the personal value and utility of the Ring 4 in the 30-day period for returns.That means that the $400+ ring and the annual subscription fee is only acceptable for those with money to burn, so to speak, because all of the shortcomings or issues, even if expandable and temporary, outweigh the cost of what is actually a pretty doggone accurate piece of tech wear, resulting in the clear choice to return the ring.AND… there is one other issue to consider which is that if your hands swell, perhaps from work, or shrink, perhaps from weight loss, then your $400+ ring AND subscription become useless… until you purchase another Ōura Ring that does fit.Based on my research and experience, there are equally accurate smart fitness watches with solid Apps and reasonable insights and suggestions based on the assessment of the biometrics.Also, there is another smart ring on the market that appears to rival the Ōura Ring in accuracy, provides an seemingly identical App for all appearances seen, comes as an adjustable ring using the same high-end materials and sensor setup AND which additionally boasts being approved and classified as a Medical Grade Device, instead of a Consumer Grade Device.All of that at a far, far lower cost AND the same updates, assessments, insights and suggestions BUT with NO subscription fee.That being said, I am a Go/No-Go tester of products meaning things are either 5-star or 1-star with enough details for people to decide that my 1-star item might be good enough to be their 3- or 4-star item.The Ring 4 failed to make the grade for my needs nor was it able to justify keeping the ring to see if things improved or the money was worth the extended wait for certain observations, but it was remarkably accurate when comparing data to manual results, such as HR, SpO2, etc.There is no blood pressure data, for those in search of BP function. I am not sure that BP could be accurately obtained below the wrist at this point in technology, but maybe in the future.REMEMBER that when returning an Ōura Ring, you MUST also CANCEL the Ōura App Subscription as it is a separate financial issue from the purchase.The subscription is free for the first 30-days and a part of setting up your account before you are able to use the App, so it’s an easy thing to forget.3) Addendum — there is a charging cable organizer with a carabineer that works GREAT for the Ōura Ring 4 charging station and cable that is available on Amazon AND IS HIGHLY RECOMMENDED.That is my next review and it will be 5-Stars.It was kind of a why-the-heck-not afterthought purchase that became an INSTANT 5-Star Should Have item as soon as I unpackaged it!!!!

Three week review.
I have only had this device for three weeks, so I feel I can’t do a complete review of the product–yet. The good and the bad for the first few weeks is what I can offer and I will update as the matrix begins to develop on the app. I believe it said up to 6 months of use to get the most of the device.I purchased this with HSA to help track my everyday vitals and use it for exactly what it is designed to do. I would compare to the Apple Watch — which I have had for years and love. I like the ease and comfort of the ring.The Oura seems to track more what I would like to use it for. So far, so good. I really love how quickly the ring gathers data and tracks it. VERY easy set up, super comfortable and stylish. Definitely take advantage of the ring sizing guide to get the perfect fit. The ring suggests course corrections and adjustments to make daily quality of life better. I have yet to dig deep into the weeds of the app, but so far, there is A LOT of information to utilize. Even more than I will use it for.Those are the perks thus far, here is the down side. The only reason for my early 4-star is two things:One, the cost. Very expensive($525), is the the cost of similar devices. I don’t mind the cost if it does what it says, which so far, yes- and beyond. The ring itself, scratches super easy. I find myself buffing daily. I am no expert on Titanium, but three weeks in with everyday wear, it looks like I’ve been wearing for years. The app does a great job explaining care. Make sure to take a look at that.Second, is the proprietary subscription. I feel that with the cost of the ring, there should be at the very least a year subscription or something similar rather than just 30 days.

Ich nutze den Oura Ring 4 nun seit einigen Wochen und bin rundum zufrieden. Die Verarbeitung ist hochwertig, der Tragekomfort hervorragend – selbst nachts stört der Ring überhaupt nicht. Die Messwerte zu Schlaf, Aktivität und Erholung sind erstaunlich präzise und helfen mir, meinen Alltag bewusster zu gestalten. Besonders die neuen Funktionen zur Hauttemperatur und Stressanalyse finde ich sehr gelungen. Wer eine unauffällige, aber leistungsstarke Alternative zu einer Smartwatch sucht, ist hier genau richtig.

Amazon で購入後、3ヶ月ほどでバッテリー周りの不具合に遭遇しました。症状としては充電台から離すとすぐにスマートフォンとのペアリングが解除されてしまうというものでした。Oura Ring のヘルプセンターの右下にチャットボットがあり AI なのでありきたりな回答なのかと思えばそうではなく- 症状を入力- 普段使用している Oura アプリのアカウントのメールアドレスを聞かれるので入力。該当メールアドレス宛に確認メールが来るので承認- 交換対象製品を確認 & 交換品の送付先を入力という、ほぼ 3 ステップで交換対応の申請が完了し、1時間程度で無料扱いの注文完了メールが届きました。指輪タイプのデバイスはバッテリー周りの不具合遭遇率が高く懸念していましたが、スムーズに交換対応が行えたのでとても良かったですし、これぐらい交換対応がスムーズなのであれば月々払っている Oura の高額なサブスク代も半額分ぐらいは Apple Care みたいな保険代だと思えば割と納得感があるなと今回のトラブル発生から一連の手続きで思いました。

I hesitated for a while before investing in this gadget. And I love my Gadgets! but after doing some homework on the competition, I decided to jump for it.First, the fit and metal colour are great, I couldn’t be happier, the quality and durability is insane, i do everything with it, I rarely take it off.The connectivity to my Samsung Z Fold6 was flawless, no hiccups, plus, everything you open the app, it updates in no time. so great compatibility.Now, you need to give it time to gather data about you, of course… it will not happen overnight which is quite right, but the intel you get afterwards is great.Your body age, sleep quality, energy available, your stress, it is such a great little ring. it is a lot of money for such a small device but the value for money is worth it.I highly recommend it if you are curious and want to be nudge in the right direction for better health.
