he educational game LetterSchool reached a milestone this week: just a few months after its release, more than 100,000 copies of the app have been sold. That’s a striking result for an app that teaches something generations of children have wrestled with: how to write letters and numbers. LetterSchool’s greatest achievement is that it creates a very stimulating learning environment, offering kids a truly compelling gaming experience. Boreaal Publishers believes the app is an important part of the solution for better handwriting education.
