Example of the success of the German app: https://www.lra-bgl.de/t/das-landratsamt/aktuelles/details/news///zwei-neue-corona-faelle-im-berchtesgadener-land/ https://www.lra-bgl.de/t/das-landratsamt/aktuelles/details/n... (sorry German) In the region of Berchtesgaden a asymptomatic person for a warning from their app and was confirmed positive. Due to the app that person didn't spread further. Now we can argue how many of such cases we need for calling it a true success and then we can discuss if a single case makes the news if that's a bad sign ... on the later it's important to mind that certainly not every case makes that news and it's from a region with low virus load to begin with.
