I love this ring. I’ve only been having to charge it about once a week so the battery lasts. I’ve definitely dropped it a lot and nothing has stopped working so it’s fairly durable. It’s also waterproof and I’ve gone swimming with it multiple times without issue. It does get scratched easily if you don’t get the matte version but I feel like that’s to be expected of most jewelry like this. It’s very accurate in its data though and helpful in tracking sleep and monitoring heart rates. You do have to keep an oura subscription for it to work but it’s pretty cheap and worth the money. ... show more

    • So functional!

I’ve had the Oura ring for a month now and I love it so much! I had wanted this ring since it first came out but could never afford it. Now that you can use your FSA/HSA, it is possible. Since I used mine, I went with my favorite color rose gold. The color itself is gorgeous but not a true rose gold. It’s more of a true gold. Doesn’t matter because it’s beautiful and so functional. I look forward to waking up and checking my stats on the app. It is so accurate too! I thought I was getting a bit sick one day and it told me to take it easy so it picked up on the changes within my body. The sleep tracking is what I mainly got the ring for. I have trouble tossing and turning all night and this ring picks up on my sleep cycles. It will give suggestions of when you should go to sleep to get a better night’s rest. It is pretty comfortable to sleep with as well. Doesn’t bother me at all. Choosing the right size of ring is very important. Since our fingers do tend to swell in our sleep and with the weather. I recommend sizing up. I usually wear a size 8 but with the sizing kit, I found I had to size up to a 9. Even when my finger has swelled, it’s not uncomfortable at least for me. I have seen a lot of people being put off on the monthly subscription. Although it would be nice not to have to pay for one, I don’t mind it. As far as the work out option, I haven’t gotten a chance to test it. I do feel it needs better options to choose from with the workout options they have. If it were more like the options on my Apple Watch, it would make it even better. I also feel the period tracking could be better. It’s very basic. Just lets you choose a start date and your flow. This is what I wish Oura could put more effort into tweaking on the app. Its period predictability is pretty spot on. But why should we have to use a separate app if we want to get a more detailed breakdown of our menstrual cycle? I know there are other competitors with more reasonable pricing but Oura really is the way to go. I was able to easily put in my order here and got it the next day! Don’t order through the Oura site though. I had an order on their site that was taking forever to get any updates on my order and as it turns out, they were so backed up because they were busy fulfilling their Amazon contract. So just cancelled with them and ordered here and it worked out. If you’re debating on getting one, just do it! ... show more

    • Great ring. Nice to have health insights
Style: Sizing Kit Color: White Size: Sizing Kit
I was on the fence for a while, but decided to splurge and buy myself an Oura ring. I wish I bought it sooner! I've been an apple watch wearer for many years, but wanted more insights as I've been on a health and wellness journey. The ring was annoying at first, but now I hardly think about it or feel it. It's light weight and not obtrusively thick. I strongly recommend getting the sizing kit first and wearing the sizer for a while to get a feel for the ring. I chose to size it to fit my left pointer finger. The battery life is insane! I only have to charge it every few days. The sensors on the 3 don't hurt or feel weird or anything. I always wondered how legit this thing was, and if they could really tell what was going on but sure enough I wore it for a small inpatient procedure and my ring told me something was greatly stressing my body and I needed to take it easy! It's wild how it just knows! I also love learning about my sleep score and what effects it. ... show more

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). ... show more
