## What is Classroom PDF?

Classroom PDF is designed with unique features to fit your teaching workflow. Use it to grade worksheets and walk-through answers in class.

DESIGNED FOR TEACHERS
There are lots of PDF apps out there, but Classroom PDF was designed specifically for classroom use. It has special features to make walking through worksheets and in-class quizzes easier.

OPEN PDF FILES AND EXPORTED SLIDE DECKS
Open any PDF file from other Apps (“open in…" from Dropbox etc.). You can even export PDFs directly from Keynote.

ADD COVERS AND TOGGLE WITH A TAP
Add covers over answers to questions, and tap to toggle them. Great for in-class quizzes or to enhance class participation.

PROJECT WIRELESSLY VIA AIRPLAY
Use an AppleTV or physical connector to mirror the iPad's screen to a projector. Walk around the class, and work 1:1 with students.

DRAW, POINT, AND ZOOM
Annotate documents with smooth ink. Write in answers or grade worksheets. Use the virtual laser-pointer to call out parts of the page.

SHARE ANNOTATED FILES
Email annotated or graded files to students. You can also export PDFs to 3rd party Apps such as Dropbox.

### 4/5 — Wonderful Teaching App!

*2019-11-08, version 2.0*

I’ve been using this app for about two years now in the lecture room presenting calculations for chemistry courses.  I can partially cover my calculations and have my students work towards one or more covers.  For this purpose, this app works wonderfully — it helps foster a more active classroom learning environment.  In addition, it makes covering calculations efficient, so I get to cover more of them in the same lecture period.  This means I get to give my students what they want: more examples to learn from and the time to talk about them.

Three things I wish were added or developed for this app:

1.  The ability to add more galleries.

2.  More ways to view files in the “gallery view.”  Perhaps a list view would be more efficient, particularly with large sets of files within galleries.  Also, it would be extremely helpful to have folders within galleries.  I have lots of files and they are getting hard to manage and/or find with the somewhat limiting gallery view.

3.  It would be extremely helpful to be able to “number” or “type or write on the back of” the Tap-on Covers.  When I present a full-page of calculations, I might have anywhere from 10-15 Tap-on Covers.  If I could label the Tap-on Covers with numbers or text, it would be easier to specify which cover I wanted my students to “calculate to” or figure out what was behind it.

Please continue developing this App!!!  It has been a great tool for my classroom.

### 5/5 — Great app

*2017-08-16*

Works well.

### 5/5 — Best friend for med school

*2014-09-26, version 1.4*

I use it for studying in med school. Better than flashcard when you are cram before the exam. Please improve "add cover function " . I use this function a lot to hide/reveal term in the books instead of spending time making flashcards.

### 5/5 — Another lovely Qrayon app~

*2014-06-17, version 1.3*

Integrates so many handy tasks. Airplay projection nice touch. Love the color coding.
