Oura

Oura is an always-on health intelligence platform designed to transform how people understand and manage their health in everyday life. Oura was built to give the body a voice—translating physiological signals across sleep, activity, readiness, stress, heart health, metabolic health, and women’s health into more than 50 metrics and predictive insights. In the third quarter of fiscal 2026, Paid Members wore Oura Ring for a median of approximately 23 hours per day, enabling continuous data capture that can help our members understand their bodies, recognize patterns early, and act with greater intention and precision. Our platform is anchored by Oura Ring, the world’s smallest smart ring. Our patented hardware is purpose-built to leverage the finger’s unique physiology and advanced sensors to deliver continuous, high-fidelity biometric data. Oura Ring lives at the intersection of wearability and capability, and is engineered for comfort and everyday wear, integrating naturally into daily life. Backed by more than a decade of research and clinical validation, Oura follows a science-first approach to product development, with Oura Ring achieving industry-leading accuracy of approximately 99% for heart rate, 98% for heart rate variability, 96% for ovulation tracking, and 96% for sleep accuracy. Since our founding in 2013, we have amassed a proprietary dataset comprising nearly 42 billion hours of longitudinal biometric data as of June 30, 2026, spanning heart rate, heart rate variability, respiration rate, body temperature, sleep stages, menstrual cycles, and activity.
