A free program for Android, by Ministero della Salute.
Immuni is an app that allows you to receive notifications of exposure to COVID-19 in order to self-isolate and avoid spreading the virus to others. The notifications are personalised and come from the government, in compliance with the law n. 28/2020.
This app allows you to track the people you were in contact with for the last 14 days. If you are not feeling well, you can easily ask the people you were in contact with for a sample.
In case you have recently come into contact with a person who is carrying the virus, you will receive an alert, and the app will guide you on what to do next, including self-isolating and getting tested.
