The curriculum

Every level, fully built and ready.

Nine complete courses. Follow the CEFR ladder from A1 to C2, or take a focused sprint to get speaking fast. Each lesson blends vocabulary, grammar, a real dialogue, a quiz, speaking practice and an AI conversation.

Level by level

What you can do at each level

From A1 to C2 \u2014 tap a card to flip and see the can-do skills and study hours.

The CEFR levels

What each level actually means.

The Common European Framework defines six levels of ability. Here is what you can do at each one — so you always know where you are and where you are headed. Tap a card to flip it.

ABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÜßABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÜß
Das Alphabet

Hear every German letter.

The German alphabet has the 26 Latin letters plus three umlauts — Ä, Ö, Ü — and the ß (Eszett). Tap any letter to hear it spoken, with a word that starts with it.

Tip: tap a tile to hear “A wie Apfel” in German.

The method

Six ways every lesson makes it stick.

Reading a rule is not learning a language. Each lesson moves you from seeing, to understanding, to actually using German out loud.
