Application ProteGo Stop Covid - Could it have been an opportunity to prevent Covid-19 spreading?

This article has several aims. The first one, based on analysis of real-life data of the first Norwegian contact tracing app “The Smittestopp app”, is to show how digital contact tracing apps work and their function and possible impact in COVID-19-crisis. I mainly focused on apps designed to automatically tell users or/and public health officials whether somebody has potentially been exposed to COVID-19. What are the factors that could impact its reception from the public opinion? The second one is to present the result of automated contact tracing apps that are backed by national governments in selected countries. And finally, I would like to look at the social, political, economic, and psychological circumstances of launching the Polish application “ProteGo Stop Covid”. I characterize the process and conditions that occurred when the Polish government was working on it and try to answer the question if it were possible to implement this process more effectively.
