Oura Health

Oura Health has commercialized multiple generations of its smart ring device—now in its fourth generation—validated against medical gold standards for biometric tracking. The company’s product has been widely adopted by consumers and organizations globally. It has demonstrated utility in large-scale deployments such as the NBA COVID response program and U.S. military contracts. Recent clinical-grade features include cardiovascular age estimation and continuous glucose monitoring integration via Dexcom Stelo biosensor. The device/app ecosystem provides actionable insights on sleep quality, metabolic status, stress levels, reproductive cycles, heart rate variability and more—but it does not diagnose or treat diseases directly.
