So functional!
I’ve had the Oura ring for a month now and I love it so much! I had wanted this ring since it first came out but could never afford it. Now that you can use your FSA/HSA, it is possible. Since I used mine, I went with my favorite color rose gold. The color itself is gorgeous but not a true rose gold. It’s more of a true gold. Doesn’t matter because it’s beautiful and so functional. I look forward to waking up and checking my stats on the app. It is so accurate too! I thought I was getting a bit sick one day and it told me to take it easy so it picked up on the changes within my body. The sleep tracking is what I mainly got the ring for. I have trouble tossing and turning all night and this ring picks up on my sleep cycles. It will give suggestions of when you should go to sleep to get a better night’s rest. It is pretty comfortable to sleep with as well. Doesn’t bother me at all. Choosing the right size of ring is very important. Since our fingers do tend to swell in our sleep and with the weather. I recommend sizing up. I usually wear a size 8 but with the sizing kit, I found I had to size up to a 9. Even when my finger has swelled, it’s not uncomfortable at least for me. I have seen a lot of people being put off on the monthly subscription. Although it would be nice not to have to pay for one, I don’t mind it. As far as the work out option, I haven’t gotten a chance to test it. I do feel it needs better options to choose from with the workout options they have. If it were more like the options on my Apple Watch, it would make it even better. I also feel the period tracking could be better. It’s very basic. Just lets you choose a start date and your flow. This is what I wish Oura could put more effort into tweaking on the app. Its period predictability is pretty spot on. But why should we have to use a separate app if we want to get a more detailed breakdown of our menstrual cycle? I know there are other competitors with more reasonable pricing but Oura really is the way to go. I was able to easily put in my order here and got it the next day! Don’t order through the Oura site though. I had an order on their site that was taking forever to get any updates on my order and as it turns out, they were so backed up because they were busy fulfilling their Amazon contract. So just cancelled with them and ordered here and it worked out. If you’re debating on getting one, just do it!

READ THE REVIEWS BEFORE YOU BUY
I want to start out by saying that this in no way is a fitness tracker, if you are into fitness in any way and have an Apple Watch continue to use your Apple Watch. If you are curious about your sleep, stress, your period cycle I would say this is a good purchase, and get the ring sizing kit. Also make sure you check with your insurance provider — they might just cover this. 1. Sleep- this really goes into detail about how much lite, deep, and REM sleep, this also calculates how long it takes you to fall asleep, your movements throughout the night, a part of this calculates your readiness (will talk about that at the end) 2. Live Heart Rate - this along with the “daytime stress feature (will do into that on 3), you can actually monitor your heart rate and do a “live” heart rate and actually feel the beats per minute, it calculates your HR in 30 minute increments. This will measure your HR at night (and it kinda calls you out if you have an elevated HR from drinking alcohol) 3. Daytime stress - the app/ ring is able to calculate your HR based on stress (this will take a couple of weeks to figure out). It tells me when I’m in relaxed, engaged and stress stage, and the restored stage (how long it will take you to recover from being stressed) this has really been helpful for me especially since working from home. This plays into your Rediness score. 4. Cycle Insights / Natural cycle- Ladies this one is for you if you are looking to come off hormonal birth control and/or looking to start a family or if you’re honestly just curious. I will say the more data that you provide the app on your last 6 periods the better it has predicting (but no worries if you don’t know it) will talk about the natural cycles app in a few. This will take your body temperature every day and create a graph, when you download the natural cycles app (which btw pairs wonderfully with the Oura ring) every morning you will open up the Oura ring app and allow everything to sync then it will transfer that data to your natural cycles app. There you will have Green Day’s ( your safe days for s*x), and red days when it’s not safe (unless looking to start a family I’m sure yours will be very different from mine). This will predict days of ovulation based on your body temp. And your est. next cycle. You will then fill out this form it will ask you if you’ve had s*x, bleeding (for period), LH test, ovulation symptoms and your overall “how are you feeling”. The more information you give the app the better. 5. Your Readiness Score - basically everything I talked about sleep, HR, temperature, “activity” even though I don’t use it. I put my Apple Watch information into it” your stress, this calculates everything and gives you a readiness score to take on your day. It may give you advice to relax, call you out on your drinking “hey your HR was elevated did you consume alcohol or have a late light snack” sometimes it can tell you that you might be coming down with something, or that you can take the day on. I will say there are CONS— it’s a wellness ring, not a fitness ring. The app…… it’s $5.99 a month… for a ring that you pay $350 based on the ring and finish. Kind of annoying. This does scuff pretty easy (so if you wear this while working out get a ring protector). However the Pro’s outweigh the cons…. I’m able to learn a lot about my sleep I’ve got some PTSD/ insomnia from the military. I’ve been able to learn a lot about my stress and period tracking. I think this was very much worth the purchase (I did hold off for a year).

Good quality
I LOVE my oura ring. It does so much. It would take forever to say it all, but I mostly use it for tracking sleep and stress. But it’s crazy to look at the app and see everything the ring caught.

Used to be a good health company, now just chasing the money
I've had an Oura ring for years now and it has been a great addition to my health routine. It mastered the basics of health tracking, spoke to Apple health to pull data in from workouts I didn't wear my ring for (ie working out with a heart rate strap) and used that data for its tracking- something others like Whoop won't do. I had a free account because of how long I've been a user and I decided to upgrade the ring to continue to support the company and because of the upgraded internals. Unfortunately they didn't tell me that buying the $400+ ring wasn't enough money for them, and they now were going to charge me a monthly fee to see the results of what the $400+ ring is measuring. Not only that but the new measurements I now have to pay for no longer talk to Apple or Polar for heart rate data during workouts, forcing you to wear the ring during workouts which is not comfortable at all. I wore it for one cycling workout and it moved too much due to sweat that even when I wore it, it couldn't get an accurate heart rate graph for me. Mind you, a cycling workout would be the least your hand is moving during a workout because it's holding the bike handle - I have no idea how it would get good data during a workout when you're using your hand to hold and move weights. Overall, great product, but the company has significantly shifted away from being concerned about making a great product that aids your life and towards one that is only concerned about nickel and diming you with a monthly subscription to make them the most money possible while trying to lock you into using their product. There's nothing in this ring that any fitness watch doesn't have, and most of them do more and without the monthly cost on top of the hundreds of dollars you have to spend on a ring that does one thing. I've moved away from this, I've advised my athletes to move away from this (I work in pro hockey), and I'd advise you to move away from this before you even get in the mix of it. There are better alternatives out there for the same amount of money that do a whole lot more, less the monthly fee.

Stopped working after 1 year
I've had this for a while now and wanted to wait to see what it does before I wrote a review. I WAS a fitbit fanatic, until now! I found the sizing kit to be accurate, the ring itself is amazing! It is intuitive once it gets to know your routine, predicts when you are getting sick, offers small reads to help with some wonky results, I love this thing. I have learned to stay active, better manage my stress, getting up early to start moving more than before, going to bed on time, and so much more! It all helps to contribute to a healthier me... I wear it in the shower, when I go swimming, no issues with being in water. UPDATE 11/2025!!! After 1 year it started to have issues, as soon as my subscription payment went in and the Gen 4 came out, this ring stopped working all together. No help from the AI assistant, how convenient for them. I really enjoyed it when it worked, but I will not be buying another Oura product. Last Update!!! After a while chatting with the AI assistant I was able to connect to an actual agent. We chatted for a while about my experience and they are doing the right thing!!! Just took a while to figure out how to actually get to a live person.

Does everything I need it to and more!
I had an Apple Watch Series 8 for a while and I liked it but after wearing it for a while it would start to get uncomfortable and become a sensory problem for me. I have autism so I'm super picky about wearing things. Strangely it also started to leave burn marks on my arm. I still wanted be able to track my sleep because I'm a chaotic sleeper and have other important information about how my body is doing. I was a little apprehensive about the Oura at first because I can't even wear normal rings so I wasn't sure I'd be able to wear this one. Now I can say the only time I've taken it off in the last 6 months is when I need to charge it. It's so comfortable I forget it's there and my finger even feels weird when I take it off. There is a subscription fee for the app but I don't mind paying it. I was paying for multiple subscriptions for my Apple watch to get all the data I needed but this is just one small subscription. I do still wear my Apple Watch for workouts (and even during that short time it's started burning my skin) because Oura isn't the best at that but it is still the best I've found for sleep and general wellness.

Great sleep and fitness tracker!
I’ve been using this ring for almost 8 months now and feel like I’m qualified to finally write a good review. Pros: -the battery life has surprised me. I might be charging it a bit more frequently than when I first got it, but it’s still lasting 4+ days after each charge -it has held up well. I wear this ring to the gym and have been amazing by how little it has actually gotten scratched. The color has held up really well. -I’ve really enjoyed the insights it’s given me. It’s caught a few times where I was getting sick before I even knew it, and I was able to load up on vitamin C to help prevent it being any worse! -it does a great job tracking my workouts and runs! Cons- Keep in mind these are super minimal compared to the pros. Just trying to think of *anything* at all. -it is a bit thick. I’m also used to wearing thin rubber rings with lots of flex and squish. -I am a touring musician and sleep lots of nights on a tour bus. Since the bus is moving and hitting bumps, it registers those as me being awake and moving and my sleep score is not even close to accurate. That’s a weird anomaly that won’t pertain to most people though. Overall - I love this thing and really enjoy keeping track of my habits!

Highly recommend
I have had my ring now for 10 months. I wear it every day, have bought the oura and natural cycling app and this is my review. I have the rose gold one as it matched my wedding set, it does have scratches in it but nothing noticeable, and the rose gold hasn’t worn at all. The oura app is nice to see my sleep and stress but I don’t really work out so I don’t think I’ll get the app again. The natural cycling app is really nice. After giving birth I got it for natural birth control and I got my period 5 months pp. I’m now almost 9 months and it’s pretty accurate as far as symptoms it suggests, days and flow of period and it has helped me understand the different phases. The ring isn’t bulky, and after the first day you don’t notice it’s even there. I got it sized to my pointer finger in the summer, so in the winter when my fingers are smaller I can put it on my middle finger and it’s not loose at all. Highly recommend. Update: I’ve had my ring and apps since June 2024. The scratches are becoming more noticeable. The apps are expensive. At 1year pp I got pregnant despite following my Green Days to a tee. Both apps informed me of an increase in temp 3 days before missed period and I tested positive.

Life-Changing Insight in a Beautiful Ring – The Ultimate Wellness Companion
I cannot express how much I love my Oura Ring – it has genuinely transformed the way I understand my body, my health, and my daily rhythm. After months of considering various wearable wellness trackers, I finally chose the Oura Ring, and I am so glad I did. It’s elegant, discreet, incredibly intelligent, and unlike anything else on the market. From the moment I received it, the packaging and unboxing experience felt premium – the attention to detail, the minimalism, and the quality of the materials made it feel more like receiving a luxury piece of jewellery than a health tracker. I opted for the Heritage design in silver, and it’s truly beautiful – sleek, modern, and subtle enough to wear with anything, from gym gear to formalwear. But the real magic lies in what it does. The Oura Ring goes far beyond basic step counting and calorie burn. It offers a holistic, science-driven picture of your health, and its insights are deeply personalised. It tracks sleep with incredible accuracy – not just how long you sleep, but your sleep stages, heart rate variability (HRV), resting heart rate, temperature trends, and respiratory rate. As someone who used to underestimate the importance of deep and REM sleep, this has been eye-opening. The sleep score helps me identify what’s helping or hindering my rest, from late-night screens to alcohol, and I now prioritise my wind-down routine because I can see the difference. Its readiness score is a game-changer. Rather than pushing you to work out every day, it guides you to tune into what your body actually needs. On days when my ring senses that my recovery is low or that I’m fighting something off, it suggests rest and gentle movement. On high readiness days, I feel confident in pushing myself further in workouts or productivity. It’s like having a silent coach on your finger who always knows how you’re doing – even when you don’t. One of the things I love most is the menstrual insights. I’ve never felt so in tune with my cycle – it predicts my period accurately and shows how my temperature and sleep shift across phases. This kind of cycle syncing helps me align workouts, productivity, and self-care to my natural hormonal rhythm. It’s empowering and refreshing to have that level of visibility without invasive apps or guesswork. Battery life is another standout feature. Unlike many wearables that need daily charging, I only need to charge the Oura Ring every 4–5 days, and the little charging dock is neat and travel-friendly. The app is intuitive, beautifully designed, and packed with information without being overwhelming. I check it every morning – not out of obsession, but because it genuinely helps me shape my day better. Whether I need to stretch more, rest more, hydrate, or move with intention, I have the data and insights to support those choices. Lastly, I appreciate that the Oura Ring is designed with privacy and longevity in mind. The company is transparent about data and constantly updating the app with useful features, like guided meditations, breathwork, and sleep audio tools. It feels like they genuinely care about their users’ long-term wellbeing. If you’re serious about understanding your body, improving your sleep, and making intentional choices around wellness and performance – all without wearing a bulky device – the Oura Ring is absolutely worth the investment. I can’t imagine life without it now. Highly, highly recommend.

Toller kleiner Helfer
Ich trage bereits seit Jahren Fitnestracker und Smartwatches, meist von Huawei oder Samsung, aber nun wollte ich mal etwas Neues probieren. Zunächst einmal habe ich mich an die Anleitung gehalten und das Size Kit bestellt. Darauf folgte die Bestellung des Ringes in der Größe 11. Passt bei mir am Zeigefinger fast perfekt und liesse sich auch noch auf dem Mittelfinger tragen. Der Tragekomfort ist super. Nach ein paar Tagen denkt man überhaupt nicht mehr an den Ring. In Schwarz gefällt er mir optisch zudem sehr gut, und das obwohl ich nie Schmuck trage. Er trägt zwar etwas dicker auf, als ein herkömmlicher Ring, aber nicht so klobrig wie man mitunter vermuten würde. Nach dem Auspacken habe ich den Ring einmal komplett geladen. Dabei kann auch im Grunde direkt die Einrichtung vorgenommen werden. Das war extrem einfach und in ein paar Minuten erledigt. Über die Abo Gebühren war ich mir schon vor dem Kauf im Klaren und habe kein Problem damit. Danach kommt man zwangsläufig direkt in die Oura App. Mir gefällt die App persönlich sehr gut, obwohl diese wohl bis vor Kurzem noch besser gewesen sein soll. Eins der letzten Updates hat die App offensichtlich umgebaut. Mich störts nicht, da ich sie ja nur so kenne. Für mich wirkt die App sehr aufgeräumt und durchdacht. Man kann im Prinzip überall drauf klicken und noch tiefer in seine Metriken blicken. Zudem gibt es zu allem kleine Erklärungen und Hinweise. Was man wissen muss, ist das manche Metriken erst nach einer gewissen Zeit angezeigt werden. Stress zum Beispiel kam bei mir zum erstem Mal nach 6 Tagen. In der App angegeben sind 5. Kardiovaskuläres Alter und Chronotyp werden ebenfalls erst noch kalibriert. Für eine Einschätzung seiner Trainingsleistung muss man einen zügigen, 6-Minütigen Spaziergang machen. Ansonsten empfinde ich die Sensoren alle als sehr genau. Lediglich auf den Schrittzähler verlasse ich mich nicht, da ich Gitarre spiele und zudem recht viel an der Tastatur arbeite. Es sollte klar sein, dass ein Ring hier anders zählt, als eine Smartwatch. Für mich kein Problem. Die Trainingserkennung funktioniert wiederum sehr gut. Sobald ich spazieren gehe, auf dem Laufband oder Crosstrainer bin, trackt der Ring sehr genau mit. Gefällt mir wirklich sehr gut. Was mir aufgefallen ist, ist dass der Ring meinen Schlaf deutlich früher ansetzt, im Gegensatz zu meiner Uhr. Sobald ich mich hinlege, auch wenn ich noch lese o.ä. wird dies als Zeit im Bett gewertet. So gesehen macht das ja auch erstmal Sinn, allerdings verfälschen sich dadurch quasi alle Schlafwerte. Ich passe die Zeit im Bett daher manuell an, denn wenn ich noch ein Stunde vor dem Schlafen lese, will ich diese Zeit nicht im Schlaftracking sehen. Wie lange der Akku hält, kann ich leider nur schätzen, aber ich würde meinen eine Woche kommt man mit einer Akkuladung hin. Ich lade meinen Ring immer beim duschen, daher kann ich das nicht genau sagen. Ob das nun alles nützlich ist, oder doch eher Spielerei, muss jeder selbst entscheiden. Ich empfinde es als nützlich und würde den Ring tatsächlich sofort wieder kaufen.

Perfecto para controlar tu cuerpo
El anillo es espectacular, perfecto para controlar tu cuerpo, mide pulsaciones, nivel de estrés, cuanto y cómo duermes, cómo respiras al dormir, registra las actividades que haces a lo largo del día, después de 3 meses de uso puedo decir que es un producto muy recomendado si te gustan las métricas de salud, es cómodo de llevar y la batería dura alrededor de 5 días, la carga es rápida cuando esto ocurra. La única pega por decir algo contrario es que tengas que pagar por la app 5 euros al mes, la cual es muy clara y totalmente en español, muy bien hecha y con actualizaciones para estar al día. En general muy contento y lo recomiendo al 100%.

Utilissimo
L'ho comprato per curiosità senza troppe aspettative invece sta diventando un ottimo strumento per tener controllato i miei parametri, soprattutto la qualità del sonno. Ho regalato a mia sorella l'ora Ring Gen2 ( per questione di misure( ed è molto valido anche quel modello pur non avendo dei report dettagliati come il modello successivo). Ottimo prodotto, esteticamente molto ben fatto e funzionale. La batteria dura una settimana quindi anche da questo punto di vista è fantastico! Consigliatissimo.
