On April 21, 2020, the project was expanded to encompass the entire Italian nation, making SM-COVID-19 the first officially sanctioned and available COVID-19 contact tracing app in Italy.

[2][3][4] It was developed pro-bono by a consortium of Italian startups SoftMining (leader), Nexus TLC, MinervaS (TruckY), PushApp and Biovista, with expertise in data analytics and web design [1].

The calculation of the risk factor developed through SM-COVID-19 was incorporated into the work of a governmental task force (Report sottogruppo di lavoro 6 - Page 11), which played a pivotal role in defining the requirements for contact tracing (CT) applications.

Due to the unavailability of the GAEN API at the application's launch, SM-COVID-19 incorporates a distance calculation correction mechanism that employs a sliding window approach alongside Received Signal Strength Indicator (RSSI) values to enhance accuracy.

[6] The effectiveness and outcomes of SM-COVID-19's deployment have been documented in a publication on the Journal of Medical Internet Research (JMIR) entitled "Evaluating Epidemiological Risk by Using Open Contact Tracing Data: Correlational Study".
