Immuni is an app created to help us fight epidemics, starting with COVID-19. The app has a contact tracing feature. When users discover they have tested positive for the virus, Immuni allows them to anonymously alert people they have been in close contact with and who may also have been infected. By being informed promptly (potentially even before developing symptoms of the virus), these people can contact their general practitioner to discuss their situation. Doing so can prevent them from infecting others, helping to reduce the spread of the virus.
