Phenomenal Sleep Tracking Tool
I got this Oura ring for my wife for Christmas this past year and she loves it as well as the rose gold color. It's a very good way to take control of your sleep and improve sleep quality. The ring tracks your sleep down to the minute, is crazy accurate, and works with an app that, once installed, works offline and connects to the ring through Bluetooth. Every morning you can get a full breakdown on the app of your sleep pattern for the night including sleep stages (light, REM, deep), heart rate, heart rate variability, body temperature, respiratory rate, total sleep vs time in bed, your sleep efficiency, your "body clock" and even "sleep debt" (which tracks how much sleep you're getting vs how much you need for your body type). It also tracks the menstrual cycle for women, which my wife uses and likes a lot. She's been able to figure out a pattern based on her heart rate that happens the day before her period actually starts, which works every time - super cool! Of course it does other things like tracks your steps, exercise, you can log your meals etc. Too many things for me to include in this review. The ring fits my wife's finger perfectly. Before you buy you have to purchase the ring sizing kit, which is cheap, and you can use it for friends if you refer people (which you can get awarded for monetarily). The sizing is pretty easy, wear one of the sizers for a day and make sure it's comfortable and then order your ring. I've also seen the ring sizing kits on display in places like Costco or Best Buy, so that's another option without having to buy the kit. The battery lasts about a week, which is pretty good. And it charges in less than an hour, sometimes half an hour if she's charging it more regularly than a week (which your supposed to do). My own Oura Ring 4 is over a year old and I have to charge it every 2-3 days. I admit, I did not follow their recommendations for maintaining the best battery life, so can't complain there. Overall, Oura Ring is fantastic and I'd highly recommend it to anyone. My wife and I have both been able to improve our overall sleep quality since using them. They are a very good tool for that if you want to prioritize sleep in relation to health (which anyone should).

Sleek, Comfortable, and Absolutely Worth It!
I’m honestly obsessed with my Oura Ring Gen 4 in silver. It’s sleek, lightweight, and fits comfortably without feeling bulky. I initially ordered a size 8, but it was too big, so I exchanged it for a size 7 and it fits perfectly. The durability seems great so far and it’s holding up really well with daily wear. It was very easy to set up, and the app made everything simple and straightforward. I’m right-handed, so I usually wear it on my left hand as recommended, but I can switch it to my right depending on what jewelry I’m wearing that day, which adds nice versatility. The tracking is impressive. My sleep insights feel accurate, and I’ve become more aware of how my rest impacts my energy and stress. Battery life is great, and it charges quickly, so I’m never without it for long. You do need the app and a small monthly membership, but overall it feels like a good value for the money. Highly recommend.

1 Month Post Purchase Review
Overall, I love it. I’m gonna break down my review as to why I love it and based on what you’re looking for in a smart ring to determine if this is a good fit for you. First, appearance. It doesn’t look masculine and is fairly scratch resistant. With any jewelry, you’re going to have a little scratching on the underside if you do anything with your hands. There’s plenty of protection options if that’s something you want to look into, but honestly I’ve had minimal scratching and it doesn’t bother me. It fit closer to my actual ring size, but you need to get sized to figure out your actual size. Oura offers a $10 you can order, but I personally just went to Best Buy and got my size off the display there. I believe Target also has sizers in the Oura display. But you do need to get fitted to know if the sensors are at an optimal location for best readings. Next category is App Quality. I really like the app and the reliability of the data it provides. I am not a super intense workout person, so it is perfect for my low impact workouts. I’ve heard people say it doesn’t provide accurate HR readings in higher intensity workouts, I see some improvement for that as you can have it track live HR data. I know a lot of people complain about the subscription and I just want to clarify that because I looked at that myself. The annual subscription is $69.99, monthly is $5.99. You can use the tracker without a subscription, however it gives you very basic data feedback. It tracks the basics, but does not give you pointers for improvement or how to better your scores. With the subscription, you’re not only paying for the insights, but you’re also paying for the access to Oura Advisor, the AI integration that can give even further insights to the data you have logged in app and the feature to simply take a photo of a meal for meal logging. Women’s Health: I personally like it. I have used Apple Health for many many years so it’s my primary for reliability in start dates, but I like the detailed data with Oura. I think with further use of the Oura I might 100% convert to it but for now I can’t decide which I like better. Given my current medical, this is a fantastic tool for me. Tags has been the best way for me to tie symptoms to more probable causes rather than wondering and guessing or assuming. I was most drawn to that feature, but you have to remember to add the tags for it to be most effective. If simple tracking without a bulky smartwatch is more what you’re looking for, this will definitely do that for you but cheaper alternatives can do the same if you’re looking to save some money. If you have more complex medical and want the data insights to your health and be more in tune with your body, you want the Oura ring with a subscription. The good news is that you can actually use an FSA / HSA for both the ring and the subscription. Mine gave me almost no trouble as far as documentation when I purchased them.

前モデルのバッテリが1日しか持たなくなったため、第4世代モデルに移行しました。機能は前モデルとほぼ同じなので、アプリサイドの更なるアップグレードを期待したいと思います。とはいえ、安定のモデルであることは間違いないです。

後で判明したがアマゾンとその他で1000円近く値段が違う。類似の商品にも出て来なかった。 24時間装着とあったので着けて寝たら、かぶれでしまった。本商品とは素材が違うが、高いので怖くて買えない
