A complete German course on your phone — with the network switched off. No account, no subscription, no ads, and no server that can go away.
German gender can't be worked out from meaning, so it has to be drilled. Every noun in Lernen is taught with its article, spoken aloud with it, and the Artikel drill makes it a daily ten from your own level.

Each lesson walks eight words up a ladder: meet them, recognise them, build them from their letters, then produce them cold. Grammar is woven through in course order.
schoen counts as schön, ss counts as ß — everywhere. The umlaut keyboard can come later.
Reviews use FSRS — the modern spaced-repetition algorithm Anki uses — bringing a word back exactly when you're about to forget it.
Wortkette, the word chain. Stadt-Land-Fluss. Diktat. Wortle. Every game feeds the same review schedule, so playing is studying.
Timed and sectioned — Wortschatz, Grammatik, Hören — generated fresh from your level each attempt, at the real 60% pass line. It rehearses the shape of the day.
„Lena in Berlin“ — six graded readers written inside the words you're learning, with comprehension questions that credit your reviews.
The bands are frequency bands, built from how German is really used — not the Goethe lists, which aren't openly licensed. At every level you learn the most useful words you don't know yet.
Every grammar point, story and sentence frame was reviewed by a German speaker before release, and the corrections are in the app. Your progress is yours: back it up to a file you choose, restore it on a new phone. Nothing is sent anywhere, ever.
