Review: If you want a fitness tracker but hate watches - this is for you! - I've had my Oura ring for almost two months and I'm very happy with it! The battery life lasts for ages and when it does get low I just charge it while I'm showering and it's back to full power. The sizing kit was really beneficial and helped me decide what size fit best for me. The price of the kit also came off the price of the Oura ring when I decided to go for it (on desertcart) and it felt like a mini discount! **girl maths** The app is brilliant and I check it every day, I think the subscription is well worth it for the information it gives you and it has made me more active and concious of making healthy decisions for my diet, exercise and sleep schedule. I recommend checking out the subreddit for Oura as well as the discussions on there are fascinating and Oura also keeps an eye on it and will fix bugs, give suggestions and understand how people are using Oura. So excited to see the insights in the future when it learns more about me!
Review: Really impressive functional ring - Bought for the wife, she loves the design with the flag edge on one side, and the functionality is pretty impressive with it even detecting when she was unwell one day!

### ⭐⭐⭐⭐⭐ Really impressive functional ring
*by S***J on 16 June 2026*

Bought for the wife, she loves the design with the flag edge on one side, and the functionality is pretty impressive with it even detecting when she was unwell one day!

### ⭐⭐⭐⭐⭐ Exceeded My Expectations!
*by M***H on 22 December 2024*

I’ve been wearing this ring since a few days ago and this has impressed me more than I expected. Not only is it comfortable to wear all day/night, but the Oura Ring app is the real star of the show! The app is simple, intuitive and informative. It can track your heart rate, stress levels, blood oxygen levels and your quality of sleep to name just a few. Even though the app requires a subscription to get all the benefits, it’s well worth it if you’re serious about looking after your own health. The important thing to remember is the Oura Ring is only a health tracker and not a fitness tracker. But it really compliments any of your devices that can track your fitness as well! Just be sure to measure your ring size before buying one as I had to for myself. I have no regrets and can easily recommend this to anyone!
