    • Apple Watch convert. Oura 4 is great
Color: Stealth Size: 14
I’m a former Apple Watch user and hated wearing the watch as I prefer a more traditional watch. Apple Watch battery life always caused me to miss sleep patterns and it always needed charging in 24 hours. It’s not for me and I also didn’t like working out with a watch on. I ended up rarely wearing the watch After fitting for the ring I went with the stealth black. The battery life has been great and so far I’m getting 7 days. It accurately tracks heart rate and sleep, which were my biggest needs but I love that I can wear it for a week straight without charging. It’s tracks way more like recovery, sleep cycles and vo2 and frankly I’m getting way more out of the ring than I expected. I also wear it when I workout including weights and it’s been unnoticeable to me unlike the Apple Watch. I love the simplicity of a ring and I’m a full convert. As for the monthly fee that some people seem to be mad about, I’m sure there are apps fees most of us are paying for other things but this fee is cheap for what it is. It’s your health after all and it’s worth it. They are also constantly improving the app and older versions of the ring work with these updates. I’m more than happy paying this fee as it’s going to improvements in health metrics (and I’m sure some profits) but it’s worth it to me because the app is very insightful and beyond my expectations. Durabilty also seems great. I’ve showered with it and worked out with barbell right on it and so far there are no scratches As for things I wish it had - The charger is meant for the ring size you buy so you are very limited in charging if you don’t have it. If you lose it you got problems. It’s not ideal but i also don’t know what could be done here There is no portable charger and it feels like a big need. I wish it had an AirPod like charging case for travel. I travel for 2-3 weeks at a time and sure wish I had a portable charger I could get a couple recharges from. They have to be working on this as it seems like a no brainer The silver interior with stealth black I wish was all black but it’s not really noticeable. Not a bud deal ... show more

The media could not be loaded. First of all, I love it, and I never leave reviews. But this needs justice. It looks like a regular ring; nobody would be able to tell the difference. The sleep tracking is super accurate, showing REM, light, and deep sleep, plus heart rate and temperature. The subscription is $6 a month, which is completely worth it in my opinion. You get detailed info on stress, recovery, and even tips for staying in sync with your body’s natural rhythm. It’s lightweight, water-resistant, and comfy enough to wear 24/7. I never take it off. It charges extremely fast, and the battery life is amazing—I only charge mine once a week. I check the app every day. It provides long-term trends and short-term data, all while giving you health advice to help you along the way. It’s super interesting. I tried to include some of the data it captures, but there’s so much to it. If you care about your wellness, this ring is definitely worth it! Everyone should have one. ... show more

    • Anticlimactic
Color: Rose Gold Size: 7
As someone who owned the GEN three, I have to say the newest one is quite a disappointment. There were a couple things I did like about the newest one. It is definitely much lighter in weight and I do like how the sensors are recessed. Unfortunately, that’s the only thing I liked about it. Mine did arrive with fingerprints all over it along with either scratches on the bottom or something stuck inside the coding. Either way for a $500 price tag that is just unacceptable. My biggest complaint however is how the rose gold looks nothing like the GEN three whatsoever. I expected some difference in the coding of course, but this essentially looks straight up gold. I’ve heard from other people the newest gold coding is almost bronze and unappealing. Or as a rose gold comes off like a dirty gold. That is unfortunately accurate. Is also misleading based upon the photos on ouras Website they definitely enhanced the color because I was expecting a beautiful rose pink light color like the current one I have from the previous generation. And it was nothing like that. It honestly just looked cheap. Sadly it’s going back. ... show more

    • Smart Tech That Blends In
Color: Brushed Silver Size: 11
The Oura Ring 4 is everything you want in a wearable — sleek, functional, and discreet. It tracks sleep, heart rate, and activity without looking like tech gear. The brushed silver finish adds a touch of class, and it’s comfortable enough to wear 24/7. The best part? An 8-day battery life! No more nightly charging sessions. I’ve noticed a real improvement in my sleep patterns, thanks to the detailed insights the app provides. If you want to prioritize health without adding clutter to your wrist, this ring is worth the investment. ... show more

    • So far, so good
Color: Gold Size: 9
I bought it for me, but the size didn’t fit. I bought the sizing set, and a size 8 fit my thumb perfectly. The actual ring slips off my finger. It’s also too bulky for my style. I prefer my watch and Apple Health, but I was looking for an alternative to night time tracking only. I gave it to my husband, who wears it on his pinky. He prefers not to wear a tracking watch, so he’s thrilled with this option. He found it easy to set up, and is very interested in the tracking details, ... show more

    • Game changer
Color: Rose Gold Size: 7
This ring knew that I was under the weather long before I started showing/feeling any symptoms. It knows more about me that I know about myself. It will certainly let me know in the morning that my energy is low because I was partying too hard. The battery life is amazing, I charge it only when I shower, my size is 7 and I find it to be very comfortable. One thing I don’t like about it is how easily it gets scratched. This is very annoying. I had it a little less than a week, and it looks like we’ve been together through fire and ice. ... show more
