Immuni was an open-sourceCOVID-19 contact tracing app used for digital contact tracing in Italy, dismissed on 31 December, 2022, after a long and debated criticism for having been a failure due to the lack of trust placed by citizens.[1][2][3][4][5] Immuni COVID-19 contact-tracing app had in fact been downloaded only by 12% of Italians between 14 and 75 years old (the government had previously stated that, in order for the app to work properly, it should have been downloaded by at least 60% of Italians).[6] It makes use of the Apple/Google Exposure Notification system.[7]
The source code was published on GitHub on the 25 May.[9] The app only works in Italy, but compatibility with other European contact tracing apps was a goal.[10] Since 19 October 2020 the app supports key-exchanges with the EU Interoperability Gateway and is therefore able to communicate with contact tracing apps of other EU countries.[citation needed]
As of 16 December 2020, the app was downloaded more than 10 million times, a number which increased to 21.882.502 downloads the day before the app's shutdown.[11]
On 27 December 2022 the Italian Ministry of Health announced that the app and its infrastructures will be dismissed on the 31 December of the same year.[12]
