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.

Oura is terrific!

Oura is just what I’ve been looking for in a fitness device—and a lot more.Have been frustrated with previous fitness bands, not very accurate, tiny screens, and need to remove whenever around water.I wasn’t looking for a device that beeps, buzzes, notifies me of calls, emails, etc. Just wanted a reliable , easy to use accurate one.Oura provides tons of data, including basic vitals, steps, detailed sleep analysis , stress levels, and lots of suggestions on how to improve health. It’s waterproof, so I never have to take it off to shower or do dishes.It’s comfortable to wear, and all the data is only available to view on your cell phone, where it’s easy to read.I haven’t yet tried all the great features, including calorie counting. So much to see and learn.I have to charge it about every 4-5 days, not a week as advertised. Charging is fast and easy.Highly recommend!

One month in! It's great!

I've been wearing the oura ring gen 4, stealth, size 9 for exactly one month now.First off, sizing.I was between sizes 9 and 10. I opted for the smaller size using this little test: Using the plastic ring sizes, if you cannot take off the ring in the morning when your fingers are puffiest, and the only way to do so is by wetting your finger to add some slippage, then that's the right size. With the bigger size, I was able to take off the ring in the morning without using water so I felt that size was too big. One month later, I am glad I went with the smaller size. No discomfort and still using water in the morning to take off the ring before I shower.ComfortI wear it on my right index finger. I did not like in between fingers, which is the reason I wear a silicone wedding band. But overall, it's not very intrusive. It's annoying to write with a pen or pencil but that's not often.AppearanceI love the stealth color. Already got a few scratches on my palm side, which is a little annoying. But I tell myself that at least the back of my hand, the ring looks like new. I use these silicone protectors when working out with weight and it does a great job. The scratches came from handling things where I should have taken off my ring. I wish there were some way to make the scratches less visible as these scratches you see a shiny silver metal which contrasts a lot!BatteryNo issues. I charge it every few days or so while I shower. I am manually trying to keep the battery at between 25% and 75% but most often I forget that I left it charging and it goes back to 100%.Sleep TrackingI'm not a power user. I enjoy checking in the morning my sleep score and compare it to how I thought my sleep went the night prior. Pretty accurate sleep tracking in my opinion.Fitness Tracking.So we all know that the step counter is way off so I don't really care about that. However, the ring really is good at spotting fitness "events" and I love that when opening the app, there's a backlog of events that you have to confirm the type of activity. My top three are: housework, walking, and HIIT. The app gets better at recognizing the events so most times I am just confirming instead of categorizing. Overall, this level of tracking is simply encouraging me to be more active, which has lead to a good impact on my health.Overall, pretty satisfied with the ring. Glad I got it.
