Luethi electronic publishing AG develops E-picture books for children of pre-reading and early reading ages. A unique feature is that the presentation of the E-books changes according to the orientation of the tablet. In landscape format soft narrating voices provide children with a fundamental literary experience as they learn to speak. Full-page illustrations complement the stories. In the illustrated portrait view children develop reading competencies. Max Bolliger’s first three picture books are available as Apps in German and English.
