Lung Passport is a digital stethoscope paired to a mobile app that examines lung problems. It lets track the condition over time and connect to the doctor remotely. The assessment is done by a neural network that correlates recorded lung sounds with specific types of abnormal sounds in seconds with medical grade accuracy. With a disease-specific questionnaire tailored to the user's profile Lung Passport can accurately identify four most common lower respiratory disorders: pneumonia, bronchitis, asthma and COPD - or absence thereof.
