    • Can’t wait for newer generations!
Style: Heritage Color: Silver Size: 9
This little piece of tech has changed my life. I’m genuinely not sure what to say. No other piece of tech I have tried including uber expensive smart watches compare to the Oura ring. I have awful chronic insomnia, my thorough research and recommendations from others led me to this. Highly accurate algorithmic monitoring for sleep, activity, stress, resilience, vitals, built in meditations, quick charging, multi-day battery, easy connectivity, ad infinitum. In my two year experience, the ring does everything Oura advertises and more. The ring quantifiably proved the pharmaceutically mediated insomnia therapy is working, I’d rather be holistic but nothing works and the ring proved that to the numerous cynically skeptical specialists and psychs. *Chef’s kiss* ... show more

    • So functional!

I’ve had the Oura ring for a month now and I love it so much! I had wanted this ring since it first came out but could never afford it. Now that you can use your FSA/HSA, it is possible. Since I used mine, I went with my favorite color rose gold. The color itself is gorgeous but not a true rose gold. It’s more of a true gold. Doesn’t matter because it’s beautiful and so functional. I look forward to waking up and checking my stats on the app. It is so accurate too! I thought I was getting a bit sick one day and it told me to take it easy so it picked up on the changes within my body. The sleep tracking is what I mainly got the ring for. I have trouble tossing and turning all night and this ring picks up on my sleep cycles. It will give suggestions of when you should go to sleep to get a better night’s rest. It is pretty comfortable to sleep with as well. Doesn’t bother me at all. Choosing the right size of ring is very important. Since our fingers do tend to swell in our sleep and with the weather. I recommend sizing up. I usually wear a size 8 but with the sizing kit, I found I had to size up to a 9. Even when my finger has swelled, it’s not uncomfortable at least for me. I have seen a lot of people being put off on the monthly subscription. Although it would be nice not to have to pay for one, I don’t mind it. As far as the work out option, I haven’t gotten a chance to test it. I do feel it needs better options to choose from with the workout options they have. If it were more like the options on my Apple Watch, it would make it even better. I also feel the period tracking could be better. It’s very basic. Just lets you choose a start date and your flow. This is what I wish Oura could put more effort into tweaking on the app. Its period predictability is pretty spot on. But why should we have to use a separate app if we want to get a more detailed breakdown of our menstrual cycle? I know there are other competitors with more reasonable pricing but Oura really is the way to go. I was able to easily put in my order here and got it the next day! Don’t order through the Oura site though. I had an order on their site that was taking forever to get any updates on my order and as it turns out, they were so backed up because they were busy fulfilling their Amazon contract. So just cancelled with them and ordered here and it worked out. If you’re debating on getting one, just do it! ... show more

    • Seems Accurate
Style: Heritage Color: Silver Size: 10
Review Image by Pierced🦋Papilio Pierced🦋Papilio
I’ve been wearing my Oura ring every day and night for a little over 3 months and it seems very accurate. I’m usually skeptical of wearable monitoring devices, but often try them nonetheless, so I use several different ones, along with non-wearable, more accurate monitors to compare reliability. The Oura seems to be spot on with my sleep, stress, and activity. It’s always detected my naps and routine “workout” activities (I created a label for my strenuous every day activities). Those are really the only stats I look at. Battery life is pretty good (mine usually needs charging nearly every 3-4 days). It’s very stylish and comfortable. I like the pulse ox and heart monitors as well. It works very well with the Apple Health app and integrates seamlessly. The Oura App is also very well designed and functions perfectly. I have not been very careful with my ring—I‘ve dropped it twice on a hard tile floor and I also wear it while working with power tools and while doing light construction/carpentry/craft work and it has held up exceptionally well. I also have worn it while washing my hands, but take it off during bathing/showering. When I first purchased it, I wore a silicone ring over it for protection, but it was too bulky. Overall, I am very happy with this tracker and would definitely recommend it. I love the sleep tracking with my Apple Watch, but sadly, it needs to be on the charging dock at night, so that feature is pretty useless for me. The Oura, however, is perfect. ... show more

    • Great Health Tracker, but Sleep Detection Needs Improvement
Style: Horizon Color: Stealth Size: 9
I’ve been using the Oura Ring Gen3 Horizon for a while now, and overall, I’m really impressed. It’s sleek, comfortable, and barely noticeable on my finger. The health tracking features—especially heart rate, activity, and readiness scores—are insightful and help me stay on top of my wellness. The battery life is also great, lasting about 4-5 days on a single charge. However, one issue I’ve noticed is that the sleep tracking isn’t always accurate. If I’m lying in bed using my phone before sleep, the ring sometimes assumes I’m already asleep, which slightly skews my sleep data. Also, it doesn’t detect naps in my car. It would be great if this could be improved in future updates. Aside from that, it’s an excellent wearable for anyone looking for a health tracker. Definitely worth considering! ... show more
