It's a good time to be Oura, the world's most prominent smart ring company . The company debuted the Oura Ring 4 in late 2024 with an updated design, slimmer sensors, and software updates. It was an unmitigated success--out of 5.5 million Oura rings sold since its inception in 2013, nearly half of them were sold in the past year.
