On September 1, 2020, an app for Android and iOS was officially launched in Portugal that allows you to track, quickly and anonymously, and through the physical proximity between 'smartphones', the contagion networks by COVID-19, informing users who have been, in the last 14 days, in the same space as someone infected with the new coronavirus.

With the name StayAway Covid, its installation is voluntary, as well is voluntary the insertion of the code that accompanies the diagnosis confirmation.
