E7mi is the official mobile application developed in Tunisia to aid in the fight against COVID-19. Available on Android and iOS, it enables users to identify the locations of individuals infected with the virus, as well as those who have come into contact with them in public spaces and on public transport. By facilitating contact tracing for both symptomatic and asymptomatic cases, E7mi enhances the speed of detection and management of COVID-19 patients, with a primary focus on communicable diseases.
