Smart Ring 4 - Stealth - Size 13 - | Non-Standard Fit – Measure with a Size Kit |Sleep, Heart Rate and Fitness Tracking Wearable | 8-Day Battery, iOS / Android Compatible

Completely addictive, so interesting in terms of the info - I’m debating moving away from my Apple Watch as the battery on this is so much better - I always charge my watch overnight but the sleep info on the Oura is great, amazing accuracy on the patterns! The battery life i would say isn’t quite as long as described but still a few days so good enough! Super easy to set up and use, debating the travel charge case but at the moment not sure it’s needed as the charger is just USB C. Definitely worth ordering the fitting measure, I wouldn’t have had a clue but annoying when you decide you want to go for it as adds a few days before you can purchase. Once bought though a perfect fit. I bought the brushed silver and have had quite a few compliments, it’s a really nice, non flashy piece that blends well with other items of jewellery. Expensive but so far I would say worth it :)

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.

Don’t know where I would be without my oura ring! It’s so interesting to know all the data about sleep, heart health etc. If you’re thinking about getting one, let this be the review that gets you one! Very, very convenient. I don’t wear my Apple Watch anymore as I’m a nurse and can’t wear watches. Would say that this is more accurate and better. Its tracks fitness, steps, sleep, women’s health etc. It also helped me conceive which I’m very grateful for. It is ‘bulky’ but you do get used to it! I often speak very highly of this product and got atleast 5 people to get one. I don't know where I’d be without my Oura ring

My wife and I bought two rings. Mine arrived complete, but my wife's was missing the ring. So I ordered another one, thinking it was just a mistake. Her second package arrived the next day with no ring in it AGAIN.

I discovered the Oura Ring 4 through the Clue period tracking app, and it’s been a total game-changer. I live with Chronic Fatigue Syndrome, Fibromyalgia, and AuDHD, and I was looking for something that could help me track sleep, stress, body temperature, and recovery. Oura delivers on all fronts—and then some. What I love most is the accuracy and depth of insight. It doesn’t just give you only the minimal data, like Deep, Light and REM sleep, but also things like how long it takes you to get to sleep (latency) and how restless you are —it then translates this into genuinely helpful feedback, like sleep and recovery scores, body temperature trends, and guided breathing for stress. The daily readiness score helps me pace myself, which is essential when managing fatigue and sensory overwhelm. The breathing and mindfulness sessions have been a great tool during flare-ups or overstimulation. A few things to note: There is a monthly app subscription, but it’s reasonably priced for what you get. I also got a month free when I signed up. The app is intuitive and easy to navigate, though some people might need a bit of time to explore all its features—there are a lot, and they’re all useful. It takes about 90 days for Oura to fully calibrate and understand your individual baseline, so the insights get better over time. Buying the sizing kit first is a MUST—you’ll want a good fit for accuracy and comfort. Tagging activities and meals is super simple (if you remember to do it). The Rest Mode is a thoughtful feature for days when you’re sick, in pain, or recovering, though I do wish stress tracking stayed active during this mode. Battery life is solid, syncing is quick, and the ring itself is lightweight and comfortable—even with sensory sensitivities. It also integrates beautifully with Clue for cycle tracking, which adds another layer of helpful data for me. If you're managing chronic illness, neurodivergence, or just want a deeper, more holistic view of your health, I can’t recommend the Oura Ring 4 enough. It’s not just about fitness—it’s about understanding your body, honoring your limits, and supporting your wellbeing.

I’ve owned the generation 3 version for some time and have just ‘upgraded’ to the generation 4. However, the ring is currently unable to display the step count with the latest firmware 2.5.3 (25th July 2025) and the iOS (Apple) operating system. This is a known issue and is being ‘actively’ investigated for a fix. I’m assured that the steps are being recorded and when the app/firmware is sorted the data will be restored. I’ll update this review. Update: within 24 hours the steps were being recorded in the app and everything works as expected. What does not work, and being worked on by Oura is the apps ability to automatically ‘guess’ at the current activity. This feature has worked on the 3 version although when I ‘chatted’ to Oura they said the version 3 would have the same issue if it was updated. Overall I think the version 4 is a more comfortable option for me, very 3 was size 10 ver 4 is a size 9. Very happy with the purchase.

Amazing tech and love it. There is a lot of stuff online about the gold coming off easily but mine has been really robust if you look after it. It’s been so good to have a tracker without a buzzing flashing screen, feels more innate and you can choose your interaction. Battery life is amazing and it does so many things when it comes to health monitoring- I’m an Oura girl now and never going back

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.

Delivery took longer than expected, but i am happy with the ring. It does exactly what they advertise. Its a nice to have.

I don't like wearing wrist watches, so having a smart ring is PERFECT for me! I love how durable it is, it's easy to clean, and the app that comes with it is GREAT! The tracking on this thing is flawless and it uses light sensors to track my vitals, so it doesn't even feel like a smart device, just a regular ring! It also charges very quickly, so if I'm using the bathroom or taking a shower at home, I just pop it on the charger for 10-15 minutes and it's good for a few days! I only do it daily just to establish a good routine, and I have forgotten before and let the battery get low, but still haven't had the power die on me yet! I can see it being an issue for lifting weights since it's coated in stainless still and a little bulky, but otherwise very comfortable for other forms of exercise! I can also see it being a problem because of the red and green light sensors at night, it might be disruptive to light sleepers in a dark room, but I just keep my hands under my blankets or pillows, and I sleep just fine! It doesn't light up all the time, just periodically throughout the night. If the tiny lights at night might bother you, you can probably put a thick sock or a glove over your hand at night to block the light. I'm personally not inconvenienced by it at night, and I like that I can't feel anything when it checks my vitals (heart rate, blood oxygen, temperature, just to name a few). I wound up subscribing to the app anually because I really liked how easy it was to set up and how thorough its analysis was for my overall health. UPDATE: Recently I noticed the ring was draining too fast between charges and I actually needed to charge it everyday! I reached out to customer service via the app, they asked a few questions, and shipped me another one immediately! It was refurbished, not brand new, but it works like new and I would never have known the difference if they didn't tell me! I keep the old one as a backup just in case since they said I don't need to send it back. I basically haven't stopped wearing the Oura ring since I put it on, and I've used it on long walks, swimming (fully submerged in water), and for general daily activities and it works great! I wash it with soap and water when I wash my hands and take it off to give it an.wxtra good wipe down before popping it on the charger or putting it back on!

Top, je suis vraiment contente de mon achat🤩

睡眠の質と日々の健康状態を把握したくて購入。 現在使い始めて5ヶ月目。 普段はPixel Watch 4をつけているけど、両方使っても全く邪魔にならない。 つけている感覚があまりないから、寝る時も気にならないのがいいところ。 事前にサイジングキットで指の太さを測ってから買ったので、フィット感はばっちり。 キットの購入代金分がしっかり割引になったのも助かった。 最初のうちはただの記録だけど、30日くらい使い続けると自分のサイクルが見えてくる。 データが蓄積されて、日々の体感とストレス測定のグラフがぴったり合うようになる。 5ヶ月間使ってみて、とくによかったのはこんなところ。 ・時計と併用しても指や手首が快適 ・30日目あたりから自分の疲れのピークがわかる ・ストレス状態の測定精度がかなり高い ・体調不良の兆候を事前に教えてくれる 一番驚いたのは体調不良の予測。 実際に体調を崩し始めたタイミングで、アプリがしっかり不調を検知していた。 ついつい無理をして、自分から休みをとれない性格の人におすすめ。 客観的なデータで「そろそろ休んだほうがいい」とストップをかけてもらえる。 今ではすっかり手放せない、健康管理のお守りになっている。
