Propeller Health developed a platform for COPD management based on a smart inhaler that communicates wirelessly with an app. The inhaler registers the dose and frequency of the COPD medication administered. The platform combines sensors, a mobile app and data analysis, and records where and when asthma symptoms occur. The app provides the user with information about things such as air quality based on a sat nav device and data from other users, and records how asthma responses differ in line with changing locations.
