Most maps drop you in the middle of the block. Ausgang gets you to the right entrance, the right station exit, the right courtyard — with live lift status and honest confidence. Never a made-up number.
Every fact carries one of four labels — official, verified, likely, uncertain — a plain-language basis, and when it was last checked. No percentages we can't stand behind.
Entrances, courtyards, and station exits with carriage hints — so you surface at the right Ausgang, not a five-minute walk from it.
Step-free access is shown with a timestamp — “lift reported working 2h ago” — never a promise the building can't keep.
The data engine, open to everyone — the same feeds that power the app.
