Apps or web-sites for detailed gis-maps

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

Hey there...

Austria is a friendly place to be in if you Google whatever every city you are in you will find an app for it.

Not sure what you are after, site maps, Metro, Railway maps?

I know what one is like in a new place so don't be afraid to ask.....

I mean web-sites or apps, with many details like what organisation is inside the house, what shops are closed or not, like Bipa or DM because Google and other apps shows not truly info. I went to a huge market in the city center in the evening and almost everything was closed. Any ideas?

Recently I've found a web-site it has all my preferences. Check this out and if you could and know please tell me a similar app. I will be grateful for any help or a piece of advice.
