Wish I bought this sooner

I’ve had my Oura ring for about 2 weeks now, and so far I love it. I bought a “random” cheaper ring first, because the price tag and subscription for Oura turned me off, but the other one didn’t work. I returned it and figured I’d try this.First off, get the sizing kit. If you try to guess based off of other rings, you’ll probably be disappointed. I sized it off of my pointer finger, with the intent to move it to smaller fingers as I start losing weight. (I have no interest in having to buy multiple rings if I can avoid it.) It can be worn on either hand, so I have lots of options to swap too as I hit my goals. The ring isn’t tiny, but it’s not obstructive. I’ve gotten used to it and it doesn’t bother me at all. I can shower with it on, wash my hands, go swimming…all the things.As for the tech and the app, super user friendly and easy to use. Everything is pretty intuitive and the data that doesn’t automatically make sense comes with explanations. You can see how everything ties together. Its predictive nature is also 2-for-2 for me. It’s reads your data in its entirety and tells you when things are a little off. I got a warning one morning when I woke up, and spiked a fever that evening. It’s also accurately predicted the timing of other things that women may find useful.One of the main reasons for me getting the Oura was to track sleep. In my opinion, it’s been pretty spot on. If I feel like I’ve laid in bed all night staring at the ceiling, my data matches that. If I feel like I passed out as soon as my head hit the pillow, the data matches it. When I wake up feeling super refreshed, and check the app, it says I slept well. When I wake up feeling like crap, surprise! The app says I slept horribly. From there, it sets your activity target for the day - based on how rested your body is.All in all, I am very happy with my purchase. Only regret is that I spent so long deciding if I really wanted it or not. But, I guess the good thing is that it seems like this model (Oura 4) has fixed a lot of problems some of the older models had. Definitely recommend!

Stylish, Insightful, and Surprisingly Comfortable — Love Everything About It

I’ve been wearing the Oura Ring Gen 4 in rose gold for several weeks now, and I genuinely love everything about it. It’s rare to find a health and wellness device that looks good — but this ring really nails it.The design is sleek and minimal, and the rose gold finish adds just the right amount of style without being flashy. It is thicker than your average accessory ring - but, it goes with everything, and I love that I can wear it 24/7 without it looking like a fitness tracker. I don't like the bulkiness of other devices so this is perfect.Comfort-wise, I barely notice it’s on — even while sleeping, which is impressive. The data it provides is clear, comprehensive, and genuinely helpful. I’ve learned so much about my sleep patterns, stress, recovery, and overall activity. The Oura app does a great job of translating data into simple, actionable insights without overwhelming you.Battery life is solid (I charge it every few days), and the charging process is quick and easy. I also appreciate the emphasis on recovery and readiness — it’s a more balanced and holistic approach than many fitness trackers I’ve used in the past.If you want a stylish, low-profile device that delivers high-quality health and wellness tracking, the Oura Ring Gen 4 is absolutely worth it.

Quite useful, despite some quirks

I bought the Oura 4 primarily to analyze my sleep, but I have ended up wearing it all day. I have an apple watch ultra that is fine for daytime activities. I thought the Oura would be better for analyzing sleep because it has the SpO2 sensors for oxygenation, and the battery lasts much longer after a charge than the apple watch. The information it gives me about the quality of my sleep is better than I expected, and I now have a better understanding of what my issues may be at night. It shows you when your oxygen levels varied during the night, which is useful, but one of its quirks is that it doesn't show you the actual timeline of blood oxygen values. I would really like to see the actual values and not just the periods of variability in a timeline. It does give the average value during sleep, and it seems to think my sleep is ok, which reassures me that I probably don't have sleep apnea. Also, I wore both my apple watch and the Oura for two nights, and they gave significantly different values for the total time awake during the night. From my own memories of waking up, the Oura seemed to be more accurate. Also, I came across a research study (paid by Oura) that compared it to the apple watch, and it claimed that the Oura was more accurate for judging time awake. My biggest surprise was today, when the Oura app told me that I was essentially under the weather and I should rest today. In fact, I haven't felt very well since yesterday. It was amazing to me that the Oura determined that. It said my nighttime temperature was elevated and my breathing rate higher than usual. But, in another quirk, it did not actually give me the numbers to back up these conclusions. Did Oura think I could not handle the truth? :) Oura likes to give general conclusions, like your activity levels are fine, your sleep was fine, etc, but it seems like it tries to avoid giving you all the raw data in some cases. I found that very annoying at first, but I am getting used to it. It does give you a time line of activity and HR. I have only had the Oura for a week, and the app has mentioned that it is establishing my baseline for the first couple of weeks. I assume that once the baseline is established, it will be able to tell me whenever I fall outside my usual range on different measures. That should be very useful. I didn't expect to like the Oura ring as much as I do, because I thought it might not provide much more information than my apple watch. But it actually does, at least during sleep. When I think I may be coming down with a bug, it is reassuring to know when the Oura thinks so too. It is also nice that I don't have to recharge it for several days. The Oura cannot replace an apple watch, of course, because it does not display messages and does not have access to apps that I use. The best of all worlds is to have both.
