ezPDF CLEAR is an acronym for "Connected Learning Easy As Read, Respond, and Repeat." It provides a pleasant reading experience with PDF documents. Combining with touch and pen technology, reading is no longer limited as a book replacement. It creates a new way of productivity tools for users to act under work or study environments on their devices - marking, writing, typing, drawing, and adding images.

However, ezPDF CLEAR now adds additional new experience - Interactivity! 

World's first introduction of PDF-based test and quiz taking mobile application.

Mimicking Books and notes are now face of the past. Learning should be more fun and responsive to attract the users' attention. Our new approach brings a passive PDF becomes live in action. Our authoring tool programs (currently available for PC only) can easily make the plain PDF file to video embedded books, audio embedded books, flashcards, OX, True/False, multiple choices, and short answer quizes and tests.

ezPDF CLEAR magically turns these contents to live interactively on mobile devices. Hope our app helps you to CLEAR your learning and training obstacles.
