Problem
Many individuals lack continuous, accurate insight into key health metrics such as sleep quality, stress, activity, heart health, and women's health, making it difficult to detect early signs of illness, optimize performance, or maintain long‑term wellbeing.
Solution
Oura offers a smart ring that continuously measures over 50 physiological signals—including heart rate, heart rate variability, respiration, temperature, blood oxygen, and movement—directly from the finger, the most reliable site for these metrics. The data are synced to the Oura app, where AI‑driven algorithms generate daily Sleep, Readiness, and Activity scores, as well as personalized guidance on stress management, recovery, and long‑term health trends. A subscription‑based Oura Membership provides ongoing access to advanced insights such as cardiovascular age, menstrual cycle predictions, illness detection, and the Oura Advisor health companion, enabling users to make data‑backed decisions about daily habits and preventive care.
