BookKrasher

**Full disclosure: This App was made custom by and for a developer who had to learn Chinese and wished desperately for a way to ease his suffering. It was a labor of love and hate. We hope it grants you the same relief and joy it has granted us.**
Learn Chinese Vocabulary by leveraging language learning principles that linguists have known for years!
