Oura Ring

Oura is a leading health technology brand most famous for the Oura Ring, a smart ring used to track sleep and physical activity. The brand was founded in Oulu, Finland, by Kari Kivelä, Markku Koskela, and Petteri Lahtela. Since its inception, Oura has evolved into a global health platform utilized by athletes and health-conscious consumers worldwide.
