RE: ID App: Every citizen in Austria has to mandatory install a new government app on their smartphone in order to keep using gov services online.

On my side, I wouldn't accept the installation of such an app on my device. Installing such an app on my device is just like allowing people to invade my privacy.
But I a quite sure that if such an app is introduced, the rate of crime in the country would reduce, because all the activities you are doing on your device would be monitored.
But I still don't support such an app
