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.

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.

I say just go for it
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been using the Oura Ring 4 and love how low-key but powerful it is. It gives me super detailed sleep and recovery data without needing to wear a bulky watch. Battery life is great, and I barely feel it on. Only downside is the monthly subscription—but honestly, the insights are worth 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.

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.

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.

Great purchase
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The fitness data collected is shared in an incredibly user-friendly way to help promote healthier lifestyle choices, such as eating better, getting more sleep, and staying active. Aesthetically it looks great and fits nicely and snug but not too tight. Haven't tried it at the gym yet, but I ordered a silicon cover so I can avoid scratching it on the weights. It's a bit pricey, but I took advantage of Black Friday deals, and I'm excited to see many insights after a year of using it.

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.

Buy it ASAP
|Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Do not hesittate. This has been the best health related item I have purchased. It tracks so much and learns your body the more you wear it. I use it with my Apple Watch to get the most accurate readings and its lifechanging if you care about tracking sleep, body temp, exercise, heart rate, body readiness, and so much more! I have no regrets. Yes, there is a subscription but with what you get out of the ring, I do not even care about it. Well worth everything.
