    • Worth the Hype
Style: Ring Size: 10 Color: Silver
Review Image by Laiz
I can honestly say the Oura Ring 5 exceeded my expectations. It’s one of those products that’s actually worth the hype. The design is beautiful and incredibly comfortable—I often forget I’m even wearing it. The battery life is excellent, the app is intuitive, and the insights go far beyond simple step counting. Sleep tracking has been incredibly detailed, and I love waking up to a complete picture of my recovery, readiness, heart rate, stress, and overall health. One feature that truly stands out is Pregnancy Insights. As someone using it throughout pregnancy, it’s been amazing to see how my body changes over time. Tracking trends like resting heart rate, body temperature, sleep quality, and recovery has given me a much better understanding of what my body is experiencing. Of course, it’s not a medical device, but it’s been an incredibly valuable wellness companion during this journey. I also appreciate how the recommendations feel personalized instead of generic. The ring has actually encouraged me to prioritize sleep and recovery, which has made a noticeable difference in how I feel day to day. If you’re on the fence because of the price, I’d say it’s an investment in your health that you’ll use every single day. For me, it’s easily become my favorite wearable, and I wouldn’t want to be without it. ... show more

    • It cuts like a normal ring and is the best health monitor

I was looking for a way to measure my sleep and activity without having the discomfort of a smart watch on my wrist all night, taking into account that I already have an apple watch I wanted to follow my metrics and sometimes this one was a little sporty for more formal outings and this ring was the perfect solution. It's super light, you get used to the few hours. What I like the most is the precision with which it analyzes the rest; the application explains very clearly how your sleep influences the energy of the next day. The battery gives me perfectly for about 5 days and charges very quickly. A key point: I recommend using the size kit before ordering it, since the fingers swell a little at night, if you are indecisa between the tightest size and the one that fits you looser I recommend the tightest believe me this ring does not compare to the plastic of the kit and it will be perfect. It is very true to the size which surprised me my size corresponds to the same that I use for traditional rings. Although it requires a monthly subscription to see all the detailed data, I have met details specifically of my body that I didn't even know for me it has been totally worth it for the comfort and discretion it offers. Aesthetically it looks beautiful and goes with everything! I bought the silver because I usually use silver accessories and it has been the best decision, one thing that I don't like so much is that it scratches easily I am a full-time housewife and in household chores in less than a month I already had several scratches but they are not visible to the naked eye. I recommend it, I love it! 😁 ... show more

I absolutely love this Oura Ring 5! The silver color is so sleek and minimalist, it looks like a normal piece of jewelry but does so much more. It fits perfectly in size 9 and I forget I'm even wearing it. The battery life is amazing and the insights about my sleep and activity have been really helpful. The packaging was also beautiful. Best tech purchase I've made this year. Highly recommend! ... show more

    • Accurate, stylish and has remained scratch free for 3 weeks
Style: Ring Size: 7 Color: Silver
Update: still a good purchase and works well. However, if you are sensitive to light at night, it will wake you up lol. From time to time, red and green lights flash from the inside of the ring. It is bright at night. Especially if you happen to move your hand near your face, it’s like someone is pointing a flashlight at you. I bought this to track my sleep which was not great before, but now I have another thing disturbing my sleep. I still give it 5 stars because it is a good smart device, but that light is killing me. 😆 So far so good. I was worried that the shiny finish was going to be a magnet for scratches, but after a week of continuous use, it has held up very well. The features are fairly similar to my Apple Watch, but I only wear that while out. Having a longer battery life and being relatively comfortable to wear has allowed me to track things that I didn’t track before such as sleep. Also, the other morning I woke up feeling extra tired. When I looked at the app it said I was showing serious signs of strain and to rest. I felt exhausted all day so it was very accurate in sensing that something was off. It has taken some getting used to because I don’t wear much jewelry and I certainly do not wear any to sleep. I am very aware that it is on in the middle of the night and find myself switching it around. It really is not that much bigger than a regular band, but if you are not used to wearing rings, it might take some time to adjust. ... show more

    • Great tracking ring with unfortunate sizing
Style: Ring Size: 7 Color: Gold
I’m so pleased with the Oura ring. I used the Apple Watch for years, but this ring tops the watch in so many ways. It tracks more accurately and gives you much better results. And you can’t beat the battery life. The sizing is my only complaint. Oura does not offer half sizes, which I need. The 6 was too small when I was working out, sleeping or just hot, when the body naturally swells due to edema. Otherwise, it fit a couple of my fingers well. I had to get the 7, which at most times easily slides off my finger and turns often. I’m constantly checking the ring to ensure the sensors are where they should be. And it only fits my right index finger. It’s too big for all my other fingers. So, all-in-all, I’m thrilled with the Oura ring and glad I purchased it. ... show more

    • Great Everyday Health Tracker
Style: Ring Size: 6 Color: Brushed Silver
Here’s a smoother, more natural version of your review: I’ve been really impressed with this ring overall. It’s extremely lightweight and comfortable to wear, even all day and overnight. The sleep tracking has been very accurate. I’ve used Apple Health for years, and since day one the ring has matched my usual sleep patterns almost perfectly. Compared to my Apple Watch, it’s usually only off by a few minutes, especially during the first week. Setting it up was incredibly fast and easy. Connecting it to my phone took only a few minutes, and syncing with both Apple Health and Strava was seamless. I also find it much more comfortable than the Oura Ring 4. I have small hands and fingers, so the Ring 5 fits me much better. As a healthcare worker who wears gloves constantly, it’s also much easier to use while working. The only real downside for me is the battery life. It doesn’t last a full week. Because I’m very active, I typically get about four days on a charge. I usually top it off while I’m showering, which helps. I also have one of the smallest ring sizes, so I think that contributes to the shorter battery life. From what I’ve read, the larger ring sizes tend to have better battery life. I chose the brushed silver finish because I wanted something that would hide scratches well, and for the most part it does. However, I accidentally scraped it against tile, and that scratch has remained, which is a little disappointing. Overall, I think it’s a great health and lifestyle tracker for everyday use. It does an excellent job tracking sleep and daily activity, and I enjoy having goals to work toward because they keep me motivated to stay healthy. I still use my Apple Watch for more intense fitness tracking, like running, but the ring has become a great companion for monitoring my overall health. ... show more

    • Oura ring 5 and 4
Style: Ring Size: 11 Color: Gold
Review Image by Art
I rarely leave reviews, but this product deserves one. I’ve been interested in the smart health ring category for a while, but I always assumed it wasn’t something I needed. I was wrong. I stopped tracking my sleep because wearing a device on my wrist at night was simply too uncomfortable. It would occasionally wake me up when I moved during sleep. Eventually, I decided to give a smart ring a try. I started with the Oura Ring 4. While I could still feel its presence during the day, it completely disappeared the moment I fell asleep. The sleep tracking seemed incredibly accurate. The ring knew the difference between simply lying still and actually being asleep. What surprised me even more was its ability to capture every single nap with precise timing, accurately detecting exactly when I fell asleep and woke up. For sleep tracking, the ring is simply perfect. Waking up with a clear understanding of how well I recovered the night before gives me genuine motivation to make better choices throughout the day, and that insight is invaluable. Plus, on days when I don’t feel like wearing a watch, I don’t have to. The ring completely covers my fitness tracking needs. It maps out exactly when my heart rate spikes throughout the day and night, making it incredibly easy to understand which activities place stress on my body and which have little impact. The real turning point happened a few days ago when I got seriously sick. The first thing I saw when opening the Oura app that morning was a warning that my body was under significant strain, along with an elevated body temperature reading. I felt absolutely terrible, and the ring knew it. It made the device feel less like a passive biometric tracker and more like a protective tool that warns you when something is wrong. Even now, when I feel almost completely recovered, the app still indicates minor signs of strain and suggests taking it easy. When I switched to the new Oura Ring 5, I was completely blown away. It practically disappeared on my finger. I should mention that choosing a slightly larger size made a huge difference. Because it isn’t squeezing my finger, it’s actually far less noticeable. I originally assumed the tighter the fit, the better, but I was wrong. The difference in weight and thickness compared to the Ring 4 is dramatic. Pictures online honestly don’t do it justice. I genuinely don’t notice it’s there anymore, whether it’s daytime or nighttime. I also love how quickly it warms up and blends with body temperature. The polished surface makes it significantly more comfortable than the plastic sizing kit rings. It was an incredibly smart decision for the company to focus on miniaturizing what was already a very successful product. On top of that, the redesigned gold finish finally looks like actual gold, and the technology now feels like a piece of jewelry rather than a gadget. Room for Improvement If I had two suggestions, the first would be the ability to manually trigger a heart rate or body temperature measurement on demand, either through a button press or a home screen widget. Even if these manual readings consumed slightly more battery, they would be highly appreciated by users who want immediate access to that information. Second, one of the best upgrades Oura could possibly introduce would be a smart alarm. Having the ring track your sleep cycles and trigger your phone alarm at the optimal moment within a designated wake-up window would make this device absolutely priceless. It’s definitely expensive, especially when you factor in the monthly subscription. However, if it fits your budget, I think you’re going to love it. ... show more

    • Love it!
Style: Ring Size: 11 Color: Silver
Review Image by Kaylee C.
I bought this because I saw that it was slimmer, and not as bulky, I could not be more happy with this purchase! I used to have the Ultrahuman air ring and the Oura ring is definitely better in my opinion. I loved my Ultrahuman but after about a year I stopped wearing it because it was just uncomfortable and I had to get a replacement about 7 months after purchasing it because it wouldn’t charge or connect to the app. The only complaint I have is that it sometimes takes a while to connect to the app (about 3 minutes or so) when you open the app. It does still scratch but it’s not super noticeable. I love the silver color because it just looks like normal jewelry. I also like that it connects to the cycle tracking with natural cycles, makes it easier to understand what my body is doing. I haven’t had any major issues with it so far and I’m hoping I don’t because I do love this ring! I had to help my fiancé work on a customer vehicle and it held up while holding heavy parts. Definitely worth the money, you get what you pay for in my opinion. ... show more
