PopApp is an application that allows developers to transform paper sketches into mobile app prototypes. These prototypes can then be shared with colleagues and friends, for a more efficient and valuable way to get feedback. PopApp is currently compatible with iPhone, iPad, Android, and desktops and has been used to create over 1.5 million sketches.
