Oura Ring 4 - Stealth - Size 5 - Smart Ring | Size First with Oura Ring 4 Sizing Kit | Sleep Tracking Wearable - Heart Rate - Fitness Tracker - Up to 8 Days Battery Life

Nice stylish ring. It is easy to set up and the battery life is great. The app is easy to use and provides great insights into health. The ring has scratched a bit but it is on my main finger so not surprising. It is pretty accurate with my exercise and sleep observations. Only “downside” would be that the ring has a light inside it to connect to your skin which my child gets distracted by at bedtime in the dark which can sometimes be frustrating but a “feature” that can’t be avoided and is understandable. Overall lovely ring.

Wow. Game changer although I am a little obsessed. It is more comfortable to wear and more accurate than my Fitbit inspire 2 as well as catching more data. Does it know when you are bad to your body absolutely yes. So it keeps you on track and today did recognise I was a bit poorly. Really happy with the purchase.

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.

I clearly have a deffective device. I have been using a v3 ring and then recently upgraded for a V4. Since then the new ring constantly loses a bluetooth connection to my phone and needs a hardware reset to connect again. This effectively makes it useless to me. I have tried using Oura support (chatbot) which gets me to remove the device from bluetooth, uninstall their app and then setup again. Over and over and over. I'm hoping to get in contact with an actual person soon but at this stage it's replace or refund. Very disappointed in the product and the support...

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.

Love this! Wear it everyday, very comfortable to wear and tracks everything I want it to track!

Loving this - I use Garmin, Aktiaa and everything elseThey all have their uses, but this is growing on me by the dayIt is also nice to be able to wear a nice watch to go outLove it !

It's a lovely looking ring, really nice and shiny but sadly the stats are inaccurate, or don't record at all. I have a Samsung Galaxy Watch 7 which I can sleep in and I find the platform much more user friendly and very accurate and provides a very indepth review of everything that the Oura ring does, minus the subscription. My watch is synced to Strava, so my activities are pulled through on there and then they come through on the Oura ring with those stats, but other stats like stress etc that Oura should measure are absent.If you have a smart watch that does everything the Oura does, you don't need this.
