## Customer Reviews

### ⭐⭐⭐⭐⭐ READ THE REVIEWS BEFORE YOU BUY
*by C***E on April 8, 2024*

I want to start out by saying that this in no way is a fitness tracker, if you are into fitness in any way and have an Apple Watch continue to use your Apple Watch. If you are curious about your sleep, stress, your period cycle I would say this is a good purchase, and get the ring sizing kit. Also make sure you check with your insurance provider — they might just cover this.1. Sleep- this really goes into detail about how much lite, deep, and REM sleep, this also calculates how long it takes you to fall asleep, your movements throughout the night, a part of this calculates your readiness (will talk about that at the end)2. Live Heart Rate - this along with the “daytime stress feature (will do into that on 3), you can actually monitor your heart rate and do a “live” heart rate and actually feel the beats per minute, it calculates your HR in 30 minute increments. This will measure your HR at night (and it kinda calls you out if you have an elevated HR from drinking alcohol)3. Daytime stress - the app/ ring is able to calculate your HR based on stress (this will take a couple of weeks to figure out). It tells me when I’m in relaxed, engaged and stress stage, and the restored stage (how long it will take you to recover from being stressed) this has really been helpful for me especially since working from home. This plays into your Rediness score.4. Cycle Insights / Natural cycle- Ladies this one is for you if you are looking to come off hormonal birth control and/or looking to start a family or if you’re honestly just curious. I will say the more data that you provide the app on your last 6 periods the better it has predicting (but no worries if you don’t know it) will talk about the natural cycles app in a few. This will take your body temperature every day and create a graph, when you download the natural cycles app (which btw pairs wonderfully with the Oura ring) every morning you will open up the Oura ring app and allow everything to sync then it will transfer that data to your natural cycles app. There you will have Green Day’s ( your safe days for s*x), and red days when it’s not safe (unless looking to start a family I’m sure yours will be very different from mine). This will predict days of ovulation based on your body temp. And your est. next cycle. You will then fill out this form it will ask you if you’ve had s*x, bleeding (for period), LH test, ovulation symptoms and your overall “how are you feeling”. The more information you give the app the better.5. Your Readiness Score - basically everything I talked about sleep, HR, temperature, “activity” even though I don’t use it. I put my Apple Watch information into it” your stress, this calculates everything and gives you a readiness score to take on your day. It may give you advice to relax, call you out on your drinking “hey your HR was elevated did you consume alcohol or have a late light snack” sometimes it can tell you that you might be coming down with something, or that you can take the day on.I will say there are CONS— it’s a wellness ring, not a fitness ring. The app…… it’s $5.99 a month… for a ring that you pay $350 based on the ring and finish. Kind of annoying. This does scuff pretty easy (so if you wear this while working out get a ring protector).However the Pro’s outweigh the cons…. I’m able to learn a lot about my sleep I’ve got some PTSD/ insomnia from the military. I’ve been able to learn a lot about my stress and period tracking. I think this was very much worth the purchase (I did hold off for a year).

### ⭐⭐⭐⭐⭐ Highly recommend
*by L***R on May 18, 2025*

I have had my ring now for 10 months. I wear it every day, have bought the oura and natural cycling app and this is my review. I have the rose gold one as it matched my wedding set, it does have scratches in it but nothing noticeable, and the rose gold hasn’t worn at all. The oura app is nice to see my sleep and stress but I don’t really work out so I don’t think I’ll get the app again. The natural cycling app is really nice. After giving birth I got it for natural birth control and I got my period 5 months pp. I’m now almost 9 months and it’s pretty accurate as far as symptoms it suggests, days and flow of period and it has helped me understand the different phases. The ring isn’t bulky, and after the first day you don’t notice it’s even there. I got it sized to my pointer finger in the summer, so in the winter when my fingers are smaller I can put it on my middle finger and it’s not loose at all.Highly recommend.

### ⭐⭐⭐⭐⭐ If you are on the fence, go for it.
*by D***R on April 27, 2025*

Love, love, love it. (Gen3, rose gold) Never got into the watches and such, but appreciate the basic information about sleep, activity, etc.However, it has more than just that - Aura shares sleep study info that you can dive into and get more info as well as other insights.As it say, try it for the 24 hrs- I tried it on 3 fingers until I found the right one where I don't feel it or it interferes. It does go at least 4-5 days without a charge. And never have a connection issue with my pixel.I have had the rose gold for over 6 months and it still looks great. I did buy protectors and will put them on, just in case.The only down side I have found is that I read every night and it doesn't like my "latency"- ie the time it takes for me to fall asleep. It dings my sleep score each night. :(
