Guys, I came at the beginning of February to Vienna, went to Salzburg once and then was in Campus because of pandemic. I am from Sacramento and I am studying here till may 2021. Two weeks ago I went to Prater and that's it. Do you know any apps like google, but with more shops and information about it or maybe web-sites. This is the first time when I am abroad and I feel confused a little bit when go out somewhere
