Happio Workshop
PDF Reader 4 is the ultimate PDF Reader for your iPad, iPhone and iPod touch. With its intuitive user interface, reading PDF documents becomes easy, efficient and enjoyable. It can also help you organize your documents. Below are some salient features highlighted:

*** Support Large PDF Documents ***
PDF Reader 4 can handle large PDF documents of more than 600 pages. It is highly optimized such that the scrolling speed and smoothness can be maintained for large documents.

*** Allow Drag N’ Drop ***
You can drag and drop files and folders. It simplifies the steps to move, copy files and create shortcuts. (for iPad only)

*** Enable Realistic Page-Flipping ***
If your document can fit into one screen, you can turn on Page Lock to lock the scroll position and zoom level. After that, you can do a finger swipe to turn to next or previous page, with realistic page-flipping animation effects!
  *** Incorporate Full Built-in Web Browser ***
The web browser in PDF Reader 4 allows you to open, bookmark web pages or set them as home page. You can also download any files from the web browser and save them for later use.
