What we stand for
Free, for every child
Our apps cost nothing, show no ads and sell nothing. There is no account to make and nothing to unlock.
Made to be accessible
Big targets, clear type, screen-reader labels, no time pressure unless you choose it, and no colour that carries meaning on its own.
In five languages
Every app speaks English, German, French and Serbian in both scripts — not just the buttons, but the countries, elements, events and paintings too.
Private by design
Nothing about a child leaves the device. Progress is saved on the phone, and settings sit behind a question only a grown-up can answer.
Built by a community
Teachers, parents and developers who want children to have good, honest software. The apps share one design system and one set of ideas: short rounds, instant feedback, and a picture of progress that a child can understand.
