Great Product
Great Product does the job on tracking sleep, heart rate, movement etc. Very easy to set up and get going. Would recommend for those that do not want to wear a smart watch.

So So Happy!
I hesitated for a while before investing in this gadget. And I love my Gadgets! but after doing some homework on the competition, I decided to jump for it. First, the fit and metal colour are great, I couldn't be happier, the quality and durability is insane, i do everything with it, I rarely take it off. The connectivity to my Samsung Z Fold6 was flawless, no hiccups, plus, everything you open the app, it updates in no time. so great compatibility. Now, you need to give it time to gather data about you, of course... it will not happen overnight which is quite right, but the intel you get afterwards is great. Your body age, sleep quality, energy available, your stress, it is such a great little ring. it is a lot of money for such a small device but the value for money is worth it. I highly recommend it if you are curious and want to be nudge in the right direction for better health.

A great tool which does exactly what it says.
The app is brilliant. It takes a while to get to know you, so don't expect instant insights, but as it builds a picture it is really good at telling you what's going on. I am using it to track my food etc as well, so not exclusively related to what's happening on the ring. On the ring specifically? Well, it is chunkier than a ring you'd buy as jewellery. That's ok and it's not ridiculous, but you have to get used to it. I do find I take it off and put it on more, or change fingers, as my hand needs a rest. The colour... Despite the name stealth, does stand out. If you want something more subtle then brushed or silver is probably better, as it's more like typical jewellery. That being said, I've gotten used to it. Sizing - definitely get the sizing kit and wear not for a few mins but for a day or two to understand how your fingers change size. Battery life is good. I reckon 8 charge it once every 4 otlr 5 days so far. I understand turning off blood oxygen measuring is the way to really eek out more battery life. You can also use airplane mode to reduce how often it speaks to your phone. But yeah, no regrets, it's a great tool and honestly, easier to live with than a smart watch.

Please don’t waste your money!
Don’t waste your money!! I have had mine 4 months and the battery is draining fast!! A very expensive piece of crap in my opinion. You also have to pay a subscription which is ridiculous!! If you want to track your health get a watch. I got conned into getting this to take my temperature, the way it is going it won’t even work in a months time and I’ll have to fork out more money! You also have to buy ring covers every month because it gets scratched very easily and it just looks like an eyesore the covers don’t last very long either!

Expensive but good value!
Really impressed, it's been tracking my sleep and helping manage my diet and exercise. It's comfortable and pretty stylish. The app is easy to use and doesn't bother me all the time with ads or useless notifications. It's very expensive and having to pay a subscription isn't the best but I think it's pretty good value for the technology in it. It was really easy to set up and hasn't had any connection drop outs or other issues. I'm a little concerned that the next ring will not be compatible with my current charger or case if I decide to get one. I hope it will be but the 3rd gen isn't compatible with 4th so that's something to know if you're buying in a few years and the 5th gen is due out. Hopefully I'm wrong and backwards and forwards compatibility won't be a problem. I like the idea of being able to give friends a discount link right from the app but it would be better if I got a month of my subscription free if they buy. I much prefer this form factor to a watch but you do give up easy heart rate monitoring so maybe a widget that can be pinned to a phone screen or even a small screen on the ring would be something cool to add in the future. Blood pressure monitoring would also really be a cool thing to add but that might not be possible. One other thing to keep in mind if you are buying is it really needs a lot of data to get the most out of it so for the first couple of weeks to a month it won't give you all the readings. In conclusion, I love it, I'm really pleased with the fit and the colour I chose. The app is great and I wish I'd had one years ago. Very happy customer.

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。

I’ve only used it for a week so I haven’t gotten the full insights it can offer, but the Oura ring 4 has been great so far. I bought it primarily to track my sleep, and it’s fascinating to track the quality of my sleep each night.
