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.

Wonderful
Amazing! The price was excellent, the quality is great, it tracks my sleep, my meals, my daily activity and it looks elegant and sleek. You can wear it for days and the battery lasts a lot. The best Christmas present!

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.

A great alternative to a smart-watch
I was keen to utilise technology to help with my fitness, but love mechanical watches so a smart-watch wasn't an option. Came across this and after some research I gave it a punt. Very happy customer, the ring is a doddle to set up and works a treat. Battery life is a snadge less than advertised but not enough to make me dock points. It's a shame about the subscription, as I think the ring is costly enough that it's something of a liberty to charge for ongoing use, they could lose things like the guided meditation etc and give a free option, or bake in more value-add to the app. Enough moaning though, what it does it does really well, giving me insights into my sleep patterns and broader health. I am happy I bought it and check the app at least daily months after buying.

Wouldn’t bother.
Doesn’t track steps accurately, doesn’t log sleep properly either. Went for a 95 minute walk yesterday, Apple Watch tracked 11000 steps, oura ring only tracked 2000, you need to manually swing your arm when walking or it doesn’t log the steps, which means if your pushing a pushchair or have your hands in your pocket or typing/talking on your phone, it won’t register your walk, which is ridiculous in 2026 for something so pricey, constantly having to think having your arms swinging by your side. I was up from 12.30am until 3.30pm last night with a crying baby, once again the apple watches picked this up and logged 3hrs 25minutes wake time, the oura however said 2hrs and a ‘good nights rest’, isn’t accurate at all and would stick with an Apple Watch if you want the most accurate results, I bought this as I got fed up of the daily charging of my watch but the ring is no use if it isn’t anywhere near accurate.

Very good but not perfect
Tracks biometrics pretty accurately. Has a premium price plus a subscription. Add to the fact that they scratch quite easily it’s not a 5 star. Comfortable to wear, much more comfortable than a watch

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.

Very comfortable to wear, lightweight and almost unnoticeable during the day and at night. Clean, minimal design that looks like a regular ring, not a gadget. Sleep, recovery and readiness insights are clear and actually useful. A great choice if you want health tracking without a watch on your wrist.
