catnclever - lernapp – Lily, Maus, Doggy

We are a young start-up based out of Switzerland, and we are parents too – passionate and enthusiastic about the importance of early childhood education!


We collaborate with leading experts in pedagogy and education, gamified learning and audiovisual design.

We are convinced that gamified learning will become increasingly relevant for educational tools in the development of early childhood curricula, giving students a headstart at school. Because of this, a gentle and safe introduction to the digital world is immensely important.

Our love of music and the arts has inspired the app's design and is one of the key success factors, in addition to the strong pedagogical concept.
