Cloudin is a system solution which includes an interactive companion device encouraging asthmatic children to use their inhaler correctly and regularly, accompanied with a mobile application for parents. The companion device is a cloud-shaped character with a digital LED display, which guides children at every stage of the inhaler use and prevents misuse of the medication. The device also senses the air quality in the child’s room and in critical situations notifies the parents via the application. The application allows parents to create the child's asthma control plan and share the reports with their doctors. Cloudin aims to increase treatment compliance by turning regular use of medication into a fun activity.
