You are more than two coordinates. Discover how your location becomes a place, one layer at a time.
An example from Berlin. Your location stays with you.
12 DISTRICTS.003 — BERLIN, WE HAVE SOMETHING FOR YOU.
We know the question. So your district takes the spotlight. Using official Berlin boundaries, the app also finds your locality — right on your device.
Kreuzberg is a locality. Friedrichshain-Kreuzberg is the district. You get both.
Berlin’s boundaries come with the app. Once your device gets a location fix, it can find your district without the internet.
You see the reported accuracy. If a district boundary falls within that range, the app tells you.

Built with Kotlin Multiplatform, Android and the prepared iOS foundation share the same interface and location logic. The Android app comes first.
006 — GOOD TO KNOW
Your location raises questions. Let’s make it simple.
Open “Wo bin ich?” and start a location search. Once your device finds a location, the app checks it against official Berlin boundaries. You see your district and locality — for example, Friedrichshain-Kreuzberg and Kreuzberg. The location display on this page is an example. The website does not request your location.
Berlin has 12 districts and 97 localities. Kreuzberg is a locality within the district of Friedrichshain-Kreuzberg. A Kiez is an everyday name for a neighbourhood whose boundaries are not always clearly defined. The app shows official districts and localities.
With a location fix, the app can identify Berlin districts and localities without the internet: the boundaries are stored on your device. A location signal, such as GPS, is still needed. Additional street addresses and new AI stories require an internet connection.
Yes. With an internet connection, an address service adds available levels such as street, city, county, state and country. The result depends on the location and the data supplied. Official offline district and locality matching is limited to Berlin.
The app considers the accuracy reported by your device. If that area crosses a boundary, it marks the result as uncertain. Location reception and granting only approximate location access can affect accuracy.
“Wo bin ich?” is currently in internal testing on Google Play. Only approved testers using the correct Google account can download it. You need Android 8 or later. A public release and an iPhone version are not yet available.

The app resolves Berlin districts and localities on-device. To enrich the result with an address, it sends coordinates over HTTPS to wobinich.lol and onward to the active address service: Google Maps Platform, or Nominatim as a fallback. Our API caches rounded coordinates and addresses in memory for up to 15 minutes plus at most 30 seconds for cleanup. There is no automatic location tracking. Optional AI stories are saved after consent, locally and for up to 90 days on the server; the original location request is not persisted.
