Underwhelming esp compared to Galaxy Watch
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I REALLY wanted to love this ring. Although I'm a tech junkie, I hate wearing a watch, especially when sleeping. But, I don't mind wearing a ring all day/night, so this seemed like a perfect solution. Unfortunately, I barely like, let alone love it. Here's why: 1. Misses 80% of my activity. Despite being advertised as tracking even "your dog walks," it misses most of these (yes, i did the proper fitting before purchase). When worn with the watch simultaneously, the watch never missed! 2. Most of the 10% it does track are delayed and I have to keep turning off/on Bluetooth for it to pick it up. It never did pick up a 20min full body workout that my watch tracked. And my watch tracks pretty much ANY movement I make. 3. Custom tags are only usable for manual activity entries, can't edit auto-captured activity with your new tag when that does work. And it doesn't keep the custom tag for re-use, you have to re-enter custom every time. 4. You have to choose between tracking calories OR steps for activities 5. Ok, so the pluses: It looks cool (I had the black one), and it really shines most at sleep tracking. Good battery life and charges very quickly. For those complaining about the "hidden" subscription fee, just do your research before purchase! If the ring were more functional, I'd happily pay the annual fee. BUT sleep tracking is not worth keeping for the price and I'll sacrifice sleep data for the more functional Samsung Galaxy Watch I already have. RETURNED!

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.

Sleek and informative
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I am very impressed with the battery life of this ring. It lasts for 4-5 days, and it charges quickly. I like the app and has many informative insights. The app reminds tou when you are getting near your sleep time. The only downside is that you have to pay for the monthly subscription or yearly. My ring gor scratched up very quickly towars the bottom but that could be because of normal activities. Defintely go in store and try on different sizes before buying.

Almost perfect !!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Almost perfect. The reason of not having 5 stars is because the tracking of my heart rate while working out isn’t accurate at all, even when having the sensor facing my palm (tried even with tape so it won’t slide) I was averaging 110 to 130 bpm while on my other more accurate tracker I was between 150-170. I think if they fix that issue this will be a perfect product. Sleep wise is hands down the best product you can get and battery also last a long time

Solid product
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I have no real complains the battery is great; it charges quickly so its not a hassle when the battery is low. sleep and heart feel really accurate detects my movement pretty well. I know it's not going to be more accurate than a smart watch but its still really really close and you dont have to carry anything bulky when youre out and about. Everything it does it does really great so if youre seeing what it can do and want that I dont see why not.

Low key but Great
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I debated long and hard on getting one of these including several weeks of trying the sizing rings on various fingers (definitely a good idea). I finally made the purchase during the July Best Buy anti-Prime Day sale. It was a great choice. I have been wearing various smartwatches from Samsung, Garmin and now a Pixel watch 3 which are handy but not great for wearing while sleeping or during things like Yoga. The Oura ring is perfect for all of that and more. I stopped noticing it almost immediately but appreciate how much info I can glean from the app from sleep info to activity tracking. It's more than enough for my needs and catches more since I wear it pretty much constantly. I still wear the watch but use it primarily as an adjunct to my phone with the ring handling the majority of the vitals tracking. My only suggestion is to invest in some of the silicon ring covers you can find on Amazon just in case you are doing something (e.g. home renovations) where you might damage the finish.

The Oura Ring is more than a fitness tracker — it’s a beautifully designed mirror into your sleep, recovery, and overall wellness. It helps me understand my body better, balance activity and rest, and make smarter daily choices. A powerful, elegant guide for anyone serious about health.

Stylish and Functional Ring
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I have been wanting to get a Oura ring for a while. I really wanted to track my sleep patterns. This ring did the trick. I can see my sleep patterns, and much more. I have yet to realize the full capability of the ring and I hope to do so soon. I would highly recommend this ring, it's not only stylish but functional.

Love - Would Buy Again
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Love my ring. As someone with high anxiety and poor sleep, this helps me to regulate and tracks the management which I'm able to share with my doctors. It also alerts me when my bio-rhythm is off which helps to "predict" my migraines.

Very Helpful
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.As a nurse with POTS I find my oura ring to be something I can’t live without. It helps me interpret what’s going on with my body as i’m not the best at listening to when I should go or when I should rest. I will say it does scratch very easily but that doesn’t bother me. I love my oura ring!

Oura Ring Gold
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I love my Oura ring. It holds charge extremely well & I got the perfect fit using the sizing kit before purchasing. It has a lot of cool features. The biggest complaints I had and why I chose 3/5 stars is because it scratches extremely easy for it being over $400 and there are a lot of other smart rings that do not require a subscription.

Hidden fees. Not “Wearable” for Half of Us
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.After three weeks of wearing an Oura Stealth on my index finger, I think until and unless Oura offers half sizes, this device should not be considered a “wearable” for many of us. I went to Best Buy to use their sizing kits and take advantage of helpful humans and same-day purchase. I was planning a trip in three weeks and wanted to test the ring’s ability to track health during travel. I found a Best Buy expert who said index is the preferred finger. A 9 was a bit tight but she said previous Oura owners were dissatisfied with results from other than a snug fit. I bought it. A week later I asked Oura Customer Service about the slight depression on my index finger and whether a ring finger is acceptable. Two days later I received a glorified AI FAQ (or rather, “FAQ off”) email with a name at the bottom to make you think a human actually spent time on it. “Naomi” said only that index is preferred and there are no half-sizes. In effect, suck it up. Even so I went back to Best Buy to size the ring finger and found a slightly better fit, but Best Buy did not have it in stock. With only a few days left before departure I decided not to risk mail order. Big mistake. I learned that fingers swell quite a lot during air travel. At some point I noticed the ring was chafing painfully. I put some soap on it to get it over the knuckle and applied it to the ring finger, where it now fit pretty well. The ring finger test lasted two days. It was looser fit and did not pick up data near as well as the index. At some point I looked down to see the ring was gone. Whether at a luggage carousel or washroom I don’t know. But good riddance. The ring was nice looking though not as sleek as my wedding band; worn on the dominant index finger it interferes a bit with pens and forks, but on the other hand it interferes unacceptably with fretting a guitar. I didn’t like the app. I wanted to check it upon waking to see how sleep went, and review activities from the previous day. Data download data from the ring takes long—OK, a tradeoff for small size and longer battery life, live with that. Pressing the top-tab for “Yesterday” takes me to a calendar from which I can select yesterday and see… today’s scores again. After fussing about in the menus I manage to find yesterday’s data curves but I’m still not sure how I got there, perhaps it just takes time for the app to retrieve the saved data from a server somewhere. Activity tracking is not intuitive. The app guesses your activity and asks you to confirm. Guesses well for playing guitar or walking—stationary bike not so well, I think because the accelerometer is not as engaged. The ring has only this, ten-minute interval heart rates, SpO2 readings and time of day as inputs, and uses some algorithms to interpolate from that. You can change the app’s guess about your activity by selecting from a list with “choices” including Finnish baseball but not, oddly enough, sex or sauna. I tried to use “Tags” feature as a workaround but the entry screen is unhelpful. I can choose Start and End times, but cannot compare to detailed heart rate graphs to refine when those happened. It takes three passes to save all three Tag data points. I got little from the analyses. It was told when I got to sleep late—I knew that without the app—but no advice on why REM and Deep sleep are consistently red, though I felt rested. (One poster on internet said he fixed his low scores but getting a different ring!) I saw interruptions in SpO2 that might mean sleep apnea—or one of five other things, like a poorly-fitting ring. I saw no info on stress levels (yet). I was consistently low on heart rate variability, which is supposedly a bad thing, but I felt fine. Maybe the ring needed more time to adjust to my personality. I was hoping to see if I needed the extra analysis provided by the add-on $5/month subscription but never did understand what was covered and what not. I see from Oura-sponsored research that Oura does a 5% better job at detecting sleep levels than other wearables; but none are as good as EEGs. Bottom line: expensive with hidden fees. If a perfect fit, it might work for you. Otherwise, until and unless Oura makes half sizes for the rest of us, their rings cannot really be considered “wearables.” Watch formats work as well for less money.

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.
