Overview
Oura makes a smart ring — worn on the finger — that continuously monitors physiological signals including heart rate, heart rate variability, skin temperature, blood oxygen saturation, and movement. These signals are processed by Oura's algorithms to generate daily Sleep, Activity, and Readiness scores, providing users with a holistic picture of their physical recovery and performance capacity. The Oura Ring 4 features an all-titanium construction, improved sensor accuracy, and a battery life of up to eight days. Health-conscious individuals, athletes, corporate wellness programs, and clinical research teams use Oura to track sleep stages, detect early signs of illness through temperature deviation, monitor menstrual cycle patterns, and guide daily activity based on physiological recovery state. Over 2 million Oura rings have been sold globally, and the platform has been deployed in peer-reviewed research studies on COVID-19 early detection, athlete recovery, and population health monitoring. Oura's differentiation lies in ring form factor accuracy: the finger offers richer blood perfusion signals than the wrist, enabling more precise heart rate and HRV measurement than most wrist-worn wearables. The company has built a clinical-grade research partner program and obtained regulatory clearances including FDA clearance for its irregular heart rhythm notification feature. A membership subscription unlocks advanced metrics and AI-generated personalized health insights.
