At the start of its operations, LetterSchool aimed to be an after class tool, a way to help kids fixate what they’ve learned at school. Because of its method and curriculum orientation, preschool and kindergarten teachers added the app to their lesson plans. Soon, many online educators started positively reviewing the app. So, the LetterSchool team started an exclusive version for teachers and schools. The version blossomed and LetterSchool for Schools is available in 11 languages and used at over 5.000 schools today.
