Oura Ring 4 - Silver - Size 9 - Size Before You Buy

I LOVE my Oura. The app is easy to use and the more you wear it, the more insight you get. Great for monitoring exercise and learning when you need to rest. It’s not cheap, but it works so well it’s decent value. Batter lasts a long time. Just wish I’d waited and got the new smaller version as it’s quite large.

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.

Horrible, doesnt accurately track sleep, very overpriced, broke in less than a year, needs to be charged everyday. Its only use is a step tracker DO NOT BUY

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.

This is the second Oura Ring I have owned, this one had a great discount in the Amazon sale so it was worth upgrading from the 3 to the 4. It looks great in Black Stealth and can handle knocks and abuse of a manual labour job. I’ve had it 6 weeks now and worn it every day to work and I still don’t see any scratches dents or marks on it. Battery life is also exceptional at 6 days, maybe 7 at a push. But it doesn’t take long to recharge either. The App that comes with it is very good as well and covers the same matrix that an iOS or Android watch does including sleep, heart rate, oxygen saturation, steps, Activity and even stress. It gives a detailed breakdown of each and depending on how interested you are you can breakdown by day, week, month or year. It can also provide weekly, monthly and yearly reports on All matrix monitored. So if you’re way over your step goal for example the app will suggest setting a higher one. It does the same with sleep etc. There is also a Rest mode if you pick up an injury or illness. I was very surprised when I had the flu and the App notified me that something was going on with my body and suggested rest mode. So if you’re a Sporty individual or just someone like me who likes to keep tabs on my health I would highly recommend this ring.

Love my Oura. It is such a great friend as it gives great insights into my activity my sleep and my wellbeing. I battery is generally pretty good. Ot is chunky but it fits nice and looks good.

It’s been one of my best decisions to buy this ring. Really insightful data and nice on the finger as well.

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

Top, je suis vraiment contente de mon achat🤩

Najlepszy tracker samopoczucia i dobrostanu

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.
