GoodReader for iPad currently retails for $4.99. As it is one of the absolute best PDF readers available, it will be the standard that is used to judge all others. This reader was the number one non-Apple app downloaded in 2010 (at that time it’s price point was only 99 cents).
The reason for its massive appeal was the support for extremely large TXT and PDF files as well as the ability to support .DOC, .PPT, and .XLS documents as well as iWork 2008 and 2009. But its utility doesn’t stop there, the GoodReader also supports audio and video files and Safari HTML archives. The interface allows hyperlinking within the text of a PDF to allow a reader to quickly jump back and forth between sections, a 50x zoom feature that is great when dealing with large maps or drawings, and a text search option that allows iPad PDF docs to be scanned for only the information that is needed.
Transferring files on the GoodReader can be done via WiFi or USB connection and with the most recent update GoodReader has gotten even better, now allowing an Annotation mode that offers text boxes, sticky notes, lines, arrows, and freehand drawings on top of a PDF files and the ability to sync with iDisk, Dropbox, SugarSync and any WebDAV, FTP or SFTP server.
This amazing app is a must have for anyone using the iPad as an eBook or PDF reader. Printing is a breeze and the annotation mode will be great for executives (or anyone who needs a signature page printed) as most older readers didn’t incorporate this into their releases.
