Oura Health is a Finnish-founded health-technology company best known for Oura Ring, a smart ring and subscription platform that measures sleep, activity, heart rate, heart-rate variability, blood oxygen, temperature trends, stress, recovery, and related biometrics. Oura applies data analytics, machine learning, and increasingly proprietary AI to deliver personalized health insights and guidance, with a stated strategic focus on preventive health, women’s health, metabolic health, and broader health intelligence. It is primarily a consumer wellness and digital-health platform rather than a provider of regulated medical diagnosis, although it has expanded partnerships and research activity involving healthcare and clinical applications. Oura is widely reported as the leading standalone smart-ring company, with approximately 74% share of the global smart-ring market in the first half of 2025 according to Omdia, and had sold more than 5.5 million rings by September 2025 according to company-reported figures cited by CNBC.
