Oura Ring 4 - Stealth - Size 12 - Sleep, Activity, Women’s Health, AI Advisor, Up to 8 Days of Battery Life, Size Before You Buy, Android & iOS Compatible

I have had my Oura ring since August 2025 and it has provided great insight to my health and fitness. I love data and the ring provides plenty of it! In the last week, it has been losing battery life quickly and I've been experiencing connection problems. I contacted Oura and via their AI support, my issue was addressed immediately with a confirmation that they would ship me a new ring. Excellent support along with a great product!

I've been wearing the oura ring gen 4, stealth, size 9 for exactly one month now. First off, sizing. I was between sizes 9 and 10. I opted for the smaller size using this little test: Using the plastic ring sizes, if you cannot take off the ring in the morning when your fingers are puffiest, and the only way to do so is by wetting your finger to add some slippage, then that's the right size. With the bigger size, I was able to take off the ring in the morning without using water so I felt that size was too big. One month later, I am glad I went with the smaller size. No discomfort and still using water in the morning to take off the ring before I shower. Comfort I wear it on my right index finger. I did not like in between fingers, which is the reason I wear a silicone wedding band. But overall, it's not very intrusive. It's annoying to write with a pen or pencil but that's not often. Appearance I love the stealth color. Already got a few scratches on my palm side, which is a little annoying. But I tell myself that at least the back of my hand, the ring looks like new. I use these silicone protectors when working out with weight and it does a great job. The scratches came from handling things where I should have taken off my ring. I wish there were some way to make the scratches less visible as these scratches you see a shiny silver metal which contrasts a lot! Battery No issues. I charge it every few days or so while I shower. I am manually trying to keep the battery at between 25% and 75% but most often I forget that I left it charging and it goes back to 100%. Sleep Tracking I'm not a power user. I enjoy checking in the morning my sleep score and compare it to how I thought my sleep went the night prior. Pretty accurate sleep tracking in my opinion. Fitness Tracking. So we all know that the step counter is way off so I don't really care about that. However, the ring really is good at spotting fitness "events" and I love that when opening the app, there's a backlog of events that you have to confirm the type of activity. My top three are: housework, walking, and HIIT. The app gets better at recognizing the events so most times I am just confirming instead of categorizing. Overall, this level of tracking is simply encouraging me to be more active, which has lead to a good impact on my health. Overall, pretty satisfied with the ring. Glad I got it.

Great for the first 6 to 8 months. From that point on the battery time became shorter and shorter and shorter. It's just a few days shy of one year and it's totally unusable now. It won't stay charged to even make it through the night. For the last few months I was having to charge it when I got home from work every day so it would make it through the night and the next day and then it got to wear I was having to charge it after work and again in the morning. It would charge up really really fast and run down really really fast eventually getting to the point where I could put it on the charger and take it off right before bedtime and it wouldn't even make it long enough to give me any data the next morning. Battery life went from almost a week to just a few hours in less than a year. Knowing what I know now I would not have wasted my money. I've since bought another brand and there's no guarantee it will last any longer but end of the day I've got $60 tied up not hundreds.

I’m a former Apple Watch user and hated wearing the watch as I prefer a more traditional watch. Apple Watch battery life always caused me to miss sleep patterns and it always needed charging in 24 hours. It’s not for me and I also didn’t like working out with a watch on. I ended up rarely wearing the watch After fitting for the ring I went with the stealth black. The battery life has been great and so far I’m getting 7 days. It accurately tracks heart rate and sleep, which were my biggest needs but I love that I can wear it for a week straight without charging. It’s tracks way more like recovery, sleep cycles and vo2 and frankly I’m getting way more out of the ring than I expected. I also wear it when I workout including weights and it’s been unnoticeable to me unlike the Apple Watch. I love the simplicity of a ring and I’m a full convert. As for the monthly fee that some people seem to be mad about, I’m sure there are apps fees most of us are paying for other things but this fee is cheap for what it is. It’s your health after all and it’s worth it. They are also constantly improving the app and older versions of the ring work with these updates. I’m more than happy paying this fee as it’s going to improvements in health metrics (and I’m sure some profits) but it’s worth it to me because the app is very insightful and beyond my expectations. Durabilty also seems great. I’ve showered with it and worked out with barbell right on it and so far there are no scratches As for things I wish it had - The charger is meant for the ring size you buy so you are very limited in charging if you don’t have it. If you lose it you got problems. It’s not ideal but i also don’t know what could be done here There is no portable charger and it feels like a big need. I wish it had an AirPod like charging case for travel. I travel for 2-3 weeks at a time and sure wish I had a portable charger I could get a couple recharges from. They have to be working on this as it seems like a no brainer The silver interior with stealth black I wish was all black but it’s not really noticeable. Not a bud deal

I first ordered a size 11 but ended up exchanging it for a size 10, which fits much better. I highly recommend using the sizing kit and wearing a few sizes over a couple of days to find the right fit to ensure an good fit. The ring itself is sleek and discreet, with a premium finish that looks great whether dressed casually or formally. Sleep tracking has been very accurate, providing detailed insights into rest, readiness, and recovery. Heart rate and activity tracking are also reliable, and the companion app is intuitive and easy to navigate. Battery life is impressive, lasting close to a week on a single charge, and charging is quick when needed. Overall, the Oura Ring 4 combines health tracking and everyday wearability better than any wrist-based device I’ve tried. Highly recommended for anyone who wants in-depth health insights in a stylish, unobtrusive form.

Great Product does the job on tracking sleep, heart rate, movement etc. Very easy to set up and get going. Would recommend for those that do not want to wear a smart watch.

Excellente bague connectée et même avec les 5,99€ par mois d’abonnement cela en vaut la peine. Je la recommande
