Caterpillar is a classroom companion app that allows students to share their reading experiences with their school communities. Children can enjoy an entirely visual platform to upload the books they read of have heard, tagging them with the emoticons that best summarise their opinions. They can then browse the other books being enjoyed by their classmates, taking part in a community that has reading at its heart.

Users are then able to search for new books to read by the recommendations of their friends and peers. The engagement of the classroom allows teacher's to be better informed of their children's tastes and preferences with books, allowing them to make more relevant recommendations and further develop a passion for reading amongst their community.
