Our Products & Services


With the help of several primary schools and universities, we develop this tailor-made mobile e-learning tool for primary schools.

Gamification is applied to encourage students to learn through playing quiz and collecting rewards.

We are also testing big data analytics in this project to provide valuable information to school teachers and researchers.


Interactive Ebook Production

Every school has a large collection of books. To have easier access to these books, we help digitize all these books and generate extra values.

Inspired by Japanese visual novels, our interactive e-books are well designed for big story structure and can combine with music or even video. Readers can make decisions to change the flow & ending of the story.

Reading & playing at the same time!
