Great Investment
Absolutely love. I tried several other rings and ended up returning them after a couple days because they gave the illusion of tracking like Oura but in the end, did not even come somewhat close to it. I love that as I was dealing with allergies/a cold (before I even really knew) the app alerted me that my symptom radar showed minor signs of straining my body, makes sense why I woke up in the middle of the night in a light sweat. I also love how it tells me about my sleep rate and if I’m in a sleep debt (I am, I know this but didn’t know how much). It knows when your heart rate changes, even when taking a nap and asks if you’d like to log the sleep. Easily connected to my iPhone without any problems AND I love the battery life warning, it lets you know when you have 24 hours left of battery I charged mine the same day every week. I am extremely active and workout most days, whether in the gym or at home, so it lasting 7 full days is great! I did not order their ring sizer but had others so I got the same ring. I do think Oura might run a little small (or maybe it’s my slight weight gain, even though I had the same size ring a couple days before getting my Oura ring), but it worked out for the better because I actually like it on my middle finger over my ring finger (who knew… I didn’t). Anyway, 10/10 recommend.

Worth the Price!
I got a size 8 and wear it on my right pointer finger—fit is true to size and very comfortable for all-day and night wear. I’m honestly amazed at how much this ring can track, from sleep and recovery to activity and overall health insights. A huge bonus is that I was able to purchase the ring with my HSA card, and even use HSA funds for the yearly subscription as well, which made this an even better value for me. The data is detailed, easy to understand, and actually useful. If you’re looking for a sleek, comfortable wearable with powerful health tracking, I highly recommend the Oura Ring

LET ME DE-INFLUENCE YOU!!!
I have had this ring for exactly 77 days and the gold is already wearing off. It leads me to wonder if they intentionally make the warranty 45 days as they know their product does not last beyond that. I’ve also never heard of such a short “warranty”. I have a desk job (engineer) and I’m not doing anything that would cause my ring to scuff up quickly. I’ve never had any other ring scratch so easily and it looks so cheap now. I’ve had $10 rings stay entirely gold for longer. It is turning silver on the top side of my finger, so it’s not even like it’s been scratching from holding things in my hand. The fact that there is a subscription on top of this is just insane. I don’t typically write reviews but I’ve never been more disappointed in a splurge purchase. The data it provides is not worth it, especially if you have a smart watch already. For the price of this ring you could buy a Garmin watch and have money left over AND not pay a subscription fee. As someone with both, a Garmin will provide you much more reliable consistent data while lasting longer on a full charge. I love my Garmin Forerunner and I find myself constantly checking the Garmin app for data because the oura app takes forever just to load.

I love it, but the gold finish scratches a bit.
I purchased the Oura Ring 4 in gold and I truly love it. What I like most is how it tracks my sleep the data is very detailed and it has helped me better understand my sleep patterns and overall energy. It’s also comfortable and you barely feel it on your finger. That said, the gold finish does scratch a bit with regular use, which was a downside for me considering the price. However, I contacted Oura’s official customer service and they were excellent they sent me a new one. Overall, I highly recommend it for the technology and insights it provides, but if you’re very particular about aesthetics, you might want to consider a different finish.

Tracks everything and is so easy to use
I finally got my hands on one of these bad boys! I took advantage of the Black Friday 30% off deal since these never go on sale! I’ve been eyeing them for over a year and wanted to pull the trigger! I’m honestly so glad i decided to get one! I love that it tracks my sleep, ovulation, stress, day to day readiness, steps, activity, etc. It’s everything I used to use other apps/watches/trackers for but in an easy, accessible, SMALL gadget. I love that it’s waterproof and I can wear it in the shower, love that i was able to get a gold ring to match my wedding ring and other jewelry i wear as well. You will have to BUY and app to get all the insights the ring has to offer, so keep that in mind. It is an annual or monthly cost of around $65 i believe. In my opinion, it’s worth it. I paid the one time annual fee to get it over with and now i don’t have to think about it. Everything is extremely easy to set up on the app, charge the ring, and set it up. I’ve had the ring a little over a week and the sleep data is my favorite right now. As a mom with a 6 mo and 22 mo, my sleep is LACKING but this helps me make sure i stay on track of it to the best of my ability right now! It lets me know how many hours i slept, my resting/sleeping heart rate, my REM, deep, and light sleep; and how long I was in each stage, tells me my readiness for the next day, etc. The ring does run larger than your normal size. I got a 9 and wear it on my middle finger which would normally be an 8. Keep that in mind. There are kits to try your size prior to buying, an a lot of stores have the try on kits to make sure you order the right size too! All in all, the ring is worth the price in my opinion and I wish i would have gotten it sooner because i love it so much!

I’m so pleased with my Oura ring! I did my research prior to buying this one and from watching people compare and test them against each other. The Oura ring would outshine them with their accuracy. It’s incredibly accurate and for the women out there it has done such a great job in predicting my menstrual cycles I don’t ever get surprised anymore. My only gripe is the fact that there is a monthly subscription charge for the app but I can look past it for now because it’s about the same as a cup of coffee. I also understand that the app is always updating and offering newer insights so I assume the cost goes towards maintaining and improving it. Although there are other brands selling at a lower price point and without a monthly membership, I would say I’m still very pleased with my purchase and I feel much more assured that it’s accuracy and insights makes the extra cost worth it

Deze Oura Ring 4 heb ik besteld, en wat krijg ik binnen? Een doos onder de vetvlekken, de zegels zijn al opengemaakt en er zit geen ring in.... ik ben zwaar teleur gesteld in de verzending door Amazon. Echter het probleem werd direct door Amazon opgelost, ik krijg een nieuw Oura Ring 4. Mijn beoordeling is van 1 naar 3 sterren gegaan. Ik kan helaas geen 4 of 5 sterren geven, aangezien ik een opengemaakte doos en ontbrekende ring ontvangen had.

I love this ring. It is a very nice gold and it work super well. It’s a touch bulky so it took a little getting used to but it tracks steps and sleep and I use it to go with the Natural Cycles app and it works so well! You can wear it doing dishes or washing hands etc too!
