"Pioneer" in "Europe"? What are the arguments for the claim that it is a pioneering work and that it is directed for use in entire Europe? Why would citizens from EU countries use this app and send their data to Swiss government? The article dosn't say anything about that after making the bold claim. The correct title should have been "Coronavirus tracing app launched in Switzerland".
All this considering that Germany has already released their own app [0].
