Wo bin ich? — A Tiny Berlin Orientation Machine
An open-source Android app that identifies your Berlin district and neighborhood, including offline.
Field notes
The app embeds Berlin boundary data so district and neighborhood matching can happen on the device, including in a poor-signal situation. Its terminology is unusually precise: Friedrichshain-Kreuzberg is identified as a district, while Kreuzberg is a neighborhood, and the page says the app covers all 12 districts and 97 neighborhoods. Optional street-name lookup uses a separate HTTPS API path through Google Maps Platform or Nominatim. The Android release is available as a signed APK; iOS support is described as preparation rather than a current release.
