Great!

Great for tracking steps and sleep but scratches
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Love the ring and the app. I gave 4 stars because I’ve only had the ring for a little over a week and it is already scratched in a couple of places. It shouldn’t be that fragile. I have to take it off when doing housework, washing dishes. Disappointing since the ceramic costs more than the metal - it should be more durable.

Oura Ring
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Got my ring 3 weeks ago. I was recently diagnosed with RA and it has already started helping me track when I’m about to have a flare up. Helps me understand a lot of what my body goes through each day. The ceramic white is so nice and goes with everything. I have small hands so it’s a little bulky for my fingers but I still love it.

Elegant Styling, A Lot of Metrics Tracked
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.INITIAL IMPRESSIONS I’ve never owned an Oura ring but have several friends that do and rave about them. As a long-time smart watch user, it was a nice change to have a more eloquent jewelry appearance. SETUP The app was easy to install, and it was very straightforward to link the ring to my account. The app is intuitive and very easy to use. The charger is compact and works with any USB-C charging cable. Initial charge took about an hour, and the ring was ready for use. The charger will turn green when ring is fully charged. USE Having never had a smart ring, I was a bit concerned about the comfort. I am not much of a jewelry wearer so getting used to it was probably more difficult than most. I did use the sizing-kit and it was very accurate. Due to all the sensors and features the ring is very thick. At first it was very uncomfortable, and I did not think I would be able to keep it for any length of time as it was more of an annoyance than I felt helpful. It took around 2 days for me to get used to wearing it and now I forget that I have it on. I do love the ceramic on the ring as I feel like it makes it more elegant and lowers the chance of scratching the ring with normal wear and tear. Also, I love that it is water resistant, so I don’t worry about leaving it on the counter while washing my hands. Oura claims a 5-to-8-day battery life. I have used the ring for five days and received a notification that I was at 22%. Recharging took approximately 45 minutes to get back to 100%. I love the battery life as I’ve owned some smart watches that need charged every day and because of this inconvenience I found myself missing out of the sleep activity. The Oura ring tracks so many things including sleep, activity, stress, readiness and women’s health. My two favorites are sleep tracking and readiness. While I have a competitor’s watch that tracks sleep, I love that this one tracks more sleep attributes. The Oura tracks total sleep, efficiency, restfulness, REM sleep, deep sleep, latency and timing. All of those are calculated to give you a sleep score and suggestions on how to improve your sleep. It also measures your average blood oxygen, your heart rate, your average HRV and lets you know if you are breathing regularly. I will say that compared to my watch my sleep score with the Oura is much higher, but it also measures far more data points to compute the score. I love the latency feature as I never knew in the past how long it took me to fall asleep. My time ranges from 5-20 minutes. At first, I was impressed until I read that target should be 15 to 20 minutes and less than 5 minutes is a sign of being overtired. The app also gives tips on how to get to sleep if having issues. My second favorite feature is the readiness tracking. This tracks your resting heart rate, your heart rate variability, your body temperature, and respiratory rate. They combine this data with your sleep, sleep balance, activity balance and recovery index to give you a readiness score between zero and 100. Since it is the weekend my readiness score was higher than the past week. Today it offered encouragement by saying I gave myself downtime and my body and mind thanked me for it. With the fast-paced life we live it is nice to get encouragement for taking a break to recharge. The activity tracker is standard with tracking steps, total calories burned, activity time and it sets a calorie burn goal for you and tracks progress towards that daily goal. The step count is within 200 steps of my watch so I would say, the Oura is very accurate. Heart rate and stress tracker are also standard and includes tracking your restorative time, stress (the amount of time your body has felt a high level of physiological stress), sleeping and activity to give you a stress time. CONCLUSIONS I am quite impressed with the Oura ring and all the features that come in such a small package. I am also impressed with the aesthetic of the Oura, it is fashionable and functional. I love all the data that is collected. I wake up and check it first thing to see how I slept and what my readiness is to prepare me for the day. There were two negatives with the Oura. First like I said prior I do not like are the initial getting used to wearing the ring and it was uncomfortable for the first 48 hours. I feel like it is thick due to all the sensors, so thick it makes my fingers seem un-natural as my pinky can’t touch my ring finger. The second thing I do not love is the annual fee to get the data. The ring is pricy compared to a smart watch and I do not get texts, or phone calls on the Oura. Even with these two negatives, I would purchase an Oura ring. I feel like the data collected is invaluable, incredibly insightful and helpful. RECOMMENDED

Nice but…
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this ring for the usual features, but when wearing it during an activity it felt bulky and not natural. I exchanged it for the Brushed Silver and this one felt much better when active.

Its has a monthly sub and won't show info without.
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The ring is not worth $500+ monthly subscription, its sort of crazy the amount of general info they restrict if you're not subscribed...like any free app is more useful....and you still have a $500 ring...that's not even collecting health data to show you anymore. They have a horrendous AI Advisor which is just a chatbot that worse with your health info and insights than ANY OTHER OPTION. Just a horrible experience all around.

My favorite health tracker!
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The Oura ring is quite impressive. I’ve used watches and bands before but I really think this is the way to go. I was skeptical at first but I absolutely love it. Build quality is amazing. I lift weights 5 days a week and I haven’t had any issues with scratches on the ceramic or anything yet. I mainly use machines at the gym that typically have plastic, rubber or foam handles so that may be why. I’m a little nervous to put it up against a steel/metal dumbbell or barbell. That being said, I think if you use gloves, you won’t have to worry about it. I also was able to get a polishing cloth sent by Oura for free but I haven’t had to use it yet. Setup was quick and easy and the app is very intuitive and easy to use. I enjoy using it. It’s a little overwhelming with all the different tabs, features, and options but once you go through it a couple of times it’s easy to get the hang of. Honestly, I don’t think I’ve discovered everything it has to offer because each time I go through the app, I learn something new. It is very comfortable. I don’t like to wear anything. Not watches, not rings, bands or anything. I just find it more comfortable to wear nothing but this ring is surprisingly comfortable. They say it’s a little thicker than the metal Oura rings but you get used to it. Or at least I did. It doesn’t bother me at all to wear it all day and night. I really wanted it to keep track of my sleep so I was a bit worried about comfort and wearing it at night but I’ve been wearing it for over a week and have no complaints on comfort at all. I wear a smart watch as well and I can tell the statistics of the ring appear to be very accurate. Especially the sleep metrics. I know when I have a bad nights sleep and every time, the Oura ring has been spot on letting me know I had a bad nights sleep and why. It’s also very accurate when I’ve had a good nights sleep. Activity, workouts, everything. The health metrics appear to be very accurate. Battery life is great. I will typically charge it when I take a shower or need to take it off to do something and don’t want to get it dirty or scratch it. It charges very fast. I’ve been able to wear it pretty much all day everyday with no battery issues by using this routine. Overall I feel like this is a great investment if you are wanting to track your health metrics and do it comfortably. I like the ring for this because it’s a no distraction, almost invisible way to track your health. It’s the only purpose. I don’t get texts or email alerts with it. It’s sole purpose is to track your health. I highly recommend it!

So much helpful health information
|Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.This is my first time using an Oura smart ring. Into it with low expectations because I already have an apple watch that tells me health information. However, the Oura ring goes into way more detail and gives advice which is much better than the apple watch. Make sure you use the Oura sizing kit before purchasing. I'm glad I did because I would have bought the wrong size ring without that kit. The price for the kit is a small amount compared to the ring itself. Setting up the Oura ring was very simple. Download the app and following the instructions. My ring needed a firmware update that it automatically did on its own. After that just start wearing the device so it can track your information. It will take a few days of wearing to get you targeted information about yourself. The ring itself is a little thick, but that's because it has to house a battery and sensors, etc. I normally do not wear rings, so it took me a few days to get used to. Thankfully the ring itself is pretty resilient as I have smashed it into things, scrapped it on things, etc and it still looks brand new. I know the metal rings show wear, but I think the ceramic will stay looking good for a long time. My biggest issue is sleep. I have trouble falling asleep or feeling well rested the next day. I cannot wear my apple watch at night to track issues because it needs to be charged. The Oura ring has lasted me 6-8 days on a charge, so this is perfect for using to track sleep. The detailed sleep information has been helpful as I'm seeing a trend of why I'm struggling. I have noticed that I'm laying in bed for a long time without falling asleep. This is because I'm playing on my phone/tablet for hours. The Oura ring app showed my sleep efficiency not great, because of my endless scrolling on my phone. So with that information I can slowly start to make changes to help get better sleep efficiency. The information is presented in such an easy way to see everything. I'm sure my apple watch can do something similar, but Oura just makes it simple to see the issues (highlighted in red in the app) and gives you information on why it could be happened and ways to remedy the issue. Since wearing the Oura ring and making the suggested changes, I have noticed that I'm starting to feel better and sleeping better. This is huge for me as I have seen many doctors who only want to prescribe medications and not get the root cause of the issue. The Oura ring app tracks more than just sleep and is a whole-body tracking device. I was really surprised at how it picked up that I was stressed. Earlier today I was having trouble logging into a website that is very important, and I was getting stressed/frustrated that I couldn't get in. When I looked at the Oura ring app it showed that information along with the time the stress happened. I really love how accurate and precise the information that the Oura ring collects and displays in the app. I know in my prior job I was stressed out about certain aspects so having it accurately measure stress would have helped me figure out the exact triggers to possibly change them. I'm so happy to have this ring as I really do see it making changes for the positive in my life. It is a little pricey, but the amount of detailed information along with help to make fixes is really worth it to me. If you are looking for an all-in-one health tracker I would recommend an Oura ring over a smart watch. The Oura ring has so much great information and help in the app that it just blows a smart watch out of the water.
