Shortsnap Learning is based in Japan and produces apps for learning English and other educational apps for most platforms.
Shortsnap has created a series for students learning English, called Chunky English.
The Chunky English Series was created to promote English Fluency. We were tired of apps that don't have an element of practice and review. So, we came up with Chunky English to help you reinforce chunks of English you sort of know but not really, and help you use the chunks of English you need to know but just can't remember. The goal of the Chunky series is to improve your English Fluency: Listening, reading and even speaking. Chunky lets you listen and practice English in fun way without getting tired of endless drills.
