A Game-Changer for Sleep Tracking
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I absolutely love my Oura Ring Gen 4, it’s hands-down one of the best purchases I’ve made for my health and wellness. I originally got it to track my sleep more accurately, and it has completely delivered on that promise (and then some). The sleep tracking is incredibly detailed—far beyond what I’ve seen in other devices. I get real-time insights into my sleep stages, restfulness, heart rate variability, body temperature, and even readiness scores that help me understand how well I recovered overnight. It’s amazing to wake up, check the app, and have a clear picture of how I slept, not just how long I was in bed. Beyond sleep, the Oura Ring also tracks activity, recovery, stress signals, and daily movement, all in a way that feels personalized and intuitive. And because it’s a ring, it’s lightweight, discreet, and comfortable—I forget I’m even wearing it. The battery life is great too; I typically get several days on a single charge. If you’re someone who values sleep quality, daily readiness, or just loves seeing detailed health metrics without wearing a bulky watch, I highly recommend the Oura Ring 4. It’s more than just a tracker—it’s a powerful tool for optimizing how you live and rest.

Solid Health Tracker with Minor Downsides
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I initially ordered the size 9 for my left index finger, but after a week I realized it slipped off every time I washed my hands. I switched to a size 8, which fits perfectly. The gold color is beautiful, though it can look slightly orangey in certain lighting. The health insights and data it provides are excellent and have already helped me be more aware of my activity and sleep. I do wish it connected more seamlessly to third-party apps like Glow or Garmin Connect. Battery life is impressive — I get about a week on a single charge. After several weeks of daily wear, I’ve had no scratches, even with workouts and handwashing. It is a bit wide for my taste since I usually wear minimalist jewelry, but it’s still very comfortable and I barely notice it on. I’ve had it for less than a month, so I’ll need more time to give a final verdict, but so far it’s been a great addition to my wellness routine.

Worth the money
||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.My girlfriend loves this ring. It's great for tracking vitals but also feminine cycles with extreme accuracy. Had to replace after a year of constant use but oura's customer service was great. Sent another within a week. It does scratch no matter how safe you are.

Great device, unusual sizing
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I'll start by saying I've been wearing an Oura ring for about 5 years. I got the OG ring with the flat side. I had the Gen 3 previously and it worked well for me, I even got a replacement from Oura when the battery started to give out. After 2 years or so, I decided I wanted to upgrade to the Ring 4. I got the sizing kit since I hadn't worn a ring without the protruding sensors before. Originally I wore a 6 for the OG and it was a bit loose. For the Gen 3, it felt more snug. When trialing the Ring 4, I got a 6 again after wearing the sizing kit since Size 5 felt too tight for my pointer finger and OK on my middle finger. I previously could wear my Gen 3 on my ring and middle interchangeably and on either hand. My dilemma was I wanted the flexibility, but for this ring, 6 was too big and 5 was too snug. Ultimately after wearing both, I opted for the Size 5 and only wear on my middle finger. It was disappointing because I sometimes like I wear other rings and move my Oura ring to my pointer finger so it doesn't scratch, but I will just have to switch it up. For me, sizing down was best and I had to forgo flexibility because I was more worried about my ring sliding off. Otherwise, good build, I like how sleek it is, and though sizing is a pain I like the flat sensors, it doesn't leave marks or dig into my finger.

Great product with great software!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Great product overall! I’ve had step trackers for a long time, but this one goes beyond, especially software wise. I think it is pretty accurate and learns your behaviors for even better future accuracy. And it looks great. I will definitely stay with this and future variants.

Best part is the battery life
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I like that I don’t have to charge it every night. I bought it to help keep track of my menstrual cycle and stress levels. Data has been pretty accurate so far.

Love it!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been using the Oura ring for a while now and I can confidently say it’s one of the best investments I’ve made for my health. It comfortable enough to wear all the time and it blends in easily to my daily life. I only have to charge it once a week for about an hour.

Oura ring

Purchase at your own risk (2 Rings lost in 1 year)
||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It’s unfortunate that I have to write this review, but if I can make one person reconsider buying this product, I can sleep better at night. I purchased my first Oura ring in January 2025 and absolutely loved it: sleek design, accurate (enough) with sleep tracking and other statistics. I own an Apple Watch and have no complaints about it, except the discomfort when sleeping, so this ring felt like a useful addition to my health-related tech. For 5-6 months, all was well until it slipped off my finger and I couldn’t find it in my apartment. I checked high and low and couldn’t find it. I used the Oura app, and the last known location was my apartment complex, but it didn't provide anything more specific like Apple's Find My feature, nor did it make any sound to help locate it. The ring eventually died, and I couldn’t do anything more to find it. I paid $80 for the 2 year protection from Geek Squad, but loss is not covered. Just like that, I was out of $400+. 6 months pass, and it’s Christmas 2025. I got a giftcard for Christmas and decided, why not get another Oura Ring and do my absolute best to keep up with it? There’s no way I can lose two $400 rings in the span of a year. I was wrong. Less than 2 months later, I’m doing my regular weekend cleaning and wearing my ring. I go to toss out the trash, and the ring slips off and down the trash chute. In a panic, I rush to the trash room, hoping to recover it using the Oura App, again to no avail. I reach out to Best Buy and Oura, neither can do anything, even with the protections I paid for (twice). To make a very long story short, if you plan to use this ring for more than just sleeping, buy something else. The sleek design is stunning, but if you can't use it without fear of scratching it or slipping off at the gym, school, work, or at home, is it worth it?. There are Reddit threads of people describing similar circumstances as I have, and I wish I trusted them. I’m out $800 in a year as a grad student and back to using my trusty Apple Watch (which now has a sleep score and other features Oura has). The best Oura will offer you for your trouble is $50-75 off a new ring.

Solid product, just wish battery life was better
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Seems to track accurately, comparable to my apple watch. Realistic battery life has been averaging around 4.5-5 days between charges.

Oura Smart Ring
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The main purpose for this purchase was to monitor my sleep. This ring does a very good job of monitoring various aspects of my health - in addition to sleep, activity, readiness for the day, stress level, heart rate, etc. I prefer it to a clunky watch. It's comfortable and I'm very pleased with the purchase.

Best Sleep & Recovery Tracker I’ve Owned
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Oura Ring 4 has completely changed how I understand my sleep and recovery. It’s incredibly comfortable — I forget I’m wearing it — yet it delivers detailed sleep staging, readiness scores, HRV, heart rate, and activity tracking that actually help me adjust my habits. The battery lasts nearly a week, the design is sleek and lightweight, and the insights in the app are clear and actionable. I’ve improved my sleep routine just by following the trends it shows me. Yes, there’s a subscription for full features, but for the depth of sleep and recovery data you get, it’s absolutely worth it. If you care about better sleep, smarter recovery, and a wearable that doesn’t get in the way, this is it.

Great alternative to leave Apple Watches
||Posted . Owned for 7 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I love this ring. I have had Apple Watches for years but got tired of not being able to wear different watches while still tracking health metrics. This is a great alternative that is stylish, accurate and the battery lasts a long time. I also like that I don't have to have another screen on my wrist and always getting notifications on another device.

Great Little Helper

I am very happy with my decision! It complements my watch in tracking my sleep, workouts, stress levels and glucose. It has helped me make some adjustments and to regulate some habits better. Great ring, unobtrusive and beneficial!

Oura Ring 4
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Excellent device - The stats are great to see and has helped me a lot with my sleep schedule. I can compare what I did on certain days that helped me get higher sleep scores. I can also compare it on nights I get terrible sleep and see what may have caused that. Overall its fantastic.

Great ring!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I love this ring! This is a great, low profile alternative to my Apple Watch - I was interested in moving away from the workout-focused watch metrics and into something more holistically body-focused, and this ring is perfect for that.
