KRAFT - Learn German in German. No translations. Made in Copenhagen

by•
KRAFT teaches German without translating into your native language. Every word is explained in German, so you think in German from day one. The app includes over 12,700 exercises, hand-drawn graphics, reading and listening stories, and an on-device AI fox companion (Fritzi) for practicing real conversations powered by Apple Intelligence, entirely offline. Built by a solo developer in Copenhagen with zero external dependencies, zero tracking, and zero data collection.

I built KRAFT because I noticed something odd about language learning apps: they all teach you German through English (or whatever your native language is). That means you’re constantly translating in your head instead of actually thinking in German. KRAFT flips this. The “Deutsch auf Deutsch” method explains every German word using other German words with hand-drawn illustrations to bridge the gap. No stock photos, no external libraries, no tracking. Every icon, every animation, every line of code is handmade. The AI conversations with Fritzi (a fox companion) run entirely on-device through Apple Intelligence, no server, no data leaves your phone. You practice real scenarios like ordering at a bakery or preparing for a job interview, all in German. I’m a solo developer based in Copenhagen. KRAFT is the app I wished existed when I started helping people around me learn German. Happy to answer any questions about the approach, the tech, or the journey.
