Klappzahl as a learning tool

Klappzahl is a clear and interactive learning tool for children and adults.

Klappzahl is an educational app that brings the classic flip-number concept into a modern digital learning environment. It helps children understand numbers, compare quantities, practise counting and develop their first arithmetic skills. Several learning modes and progressive difficulty levels support individual learning at an appropriate pace.

In addition to the decimal system, the app supports number systems from base 2 to base 16, making it suitable not only for mathematics education but also for introducing fundamental computer science concepts.

The app runs entirely locally on the device and is available for iPhone, iPad and Android. It can be used both for independent learning at home and as a valuable teaching aid in the classroom.
