Review: Best bit of health kit I’ve bought! - 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 :)
Review: 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.

### ⭐⭐⭐⭐⭐ Perfect screen-free upgrade from the Fitbit Charge 6!
*by D***S on 12 October 2026*

I bought the Oura Ring 4 in Gold as a gift for my partner to replace her Fitbit Charge 6, and it has been a massive upgrade. She wanted something less bulky that didn't look like a fitness tracker, and this fits the bill perfectly since it looks just like regular jewelry. While she missed having a screen at first, she absolutely loves the "Circles" feature in the app. It has a built-in friend tracker that lets her share and compare her readiness and activity scores with her friends. It has actually made her much more active because she is always trying to stay on top of the leaderboard amongst her friends! The sleep tracking is incredibly accurate, the battery lasts for days, and it looks beautiful. It was the perfect gift.
