Lese-Abenteuer: an open book with stars for the three difficulty levels

Lese-Abenteuer

Learning to read with stories and games: 50 stories, vocabulary, and reading, writing and grammar games at three difficulty levels. For children in grades 1 to 3. All stories are read aloud in a natural-sounding voice, not a robotic computer voice, so children can read and listen along, even if German is their second language. There are also printable PDF worksheets for the stories.

Unser Sonnensystem: the sun and planets on their orbits against a starry sky

Unser Sonnensystem

A journey through our solar system for grade 2: at each station, children get to know a planet, solve a quiz and play small games. Natural voices read all texts aloud, and the character Kiko accompanies the journey with a voice of its own. This helps children who are not yet confident readers or who are learning German as a second language.

Data protection and safety

With children, we take this especially seriously. This is what you and parents can rely on:

Children need no account and enter neither a name nor an email address.

Data stays on the device

Points and learning progress are stored only in the browser of the device in use, not on our servers.

No ads, no tracking

No advertising, no analytics tools and no in-app purchases.

Encrypted and revFADP-compliant

All apps run over an encrypted connection and are designed in line with Swiss data protection law.
