Oura Ring Generation 3 Review

With its third-generation smart ring, Oura is debuting continuous heart rate tracking, blood oxygen monitoring and period prediction. (image credit: Pocket-lint)
The all-titanium design means it’s nice and light, making it ideal to wear day and night, and it’s one you can largely forget about when it’s on. (image credit: Pocket-lint)
The sensors are neatly hidden on the non-allergenic, non-metallic inner moulding of the ring, which we find never rubs against our finger or creates discomfort. (image credit: Pocket-lint)
It uses PPG-style sensors to track heart rate and respiration, with an accelerometer used to log movement and sleep. Body temperature data is also tracked. (image credit: Pocket-lint)
The app's readiness, sleep and activity metrics are all really straightforward, and, crucially, the data feels reliable - particularly with sleep tracking. (image credit: Pocket-lint)
It's not cheap, but this is a unique option that excels in pretty much everything it attempts. It's comfortably the best smart ring on the market right now. (image credit: Pocket-lint)
