Free German learning app for expats in Germany. I moved here and realized no app taught me the German I actually needed at the Bürgeramt, doctor's office, or bank. So I built one. Spaced repetition vocabulary with native audio, interactive scenarios for real situations like registering your address or explaining symptoms to a doctor, themed decks, and a glossary. Available on Android and iOS. Completely free, no paywalls.
