Javelin is a special PDF reader for books, articles and similar documents, with or without document authorization. The app supports PDF reading functionality and navigation via the Contents icon, embedded hyperlinks, bookmarks and similar features. Bookmarking, Annotation and highlighting/markup features are supported in the PDF reader.

Documents can be downloaded to the app in one of three principal ways: (i) by using the download icon in the toolbar and entering a full URL; or (ii) by file sharing via iTunes - files may be downloaded or shared that have the file extensions .pdf and .drmz; and (iii) the app supports a third file format, which is an xml structure for lists of documents. This essentially provides a shortcut for the download procedure, as the xml file includes a description of the file and the url of the file to be downloaded, thereby simplifying the download process for the user. These xml lists can themselves be downloaded via an explicit URL download request or may be pre-loaded - a sample catalog is pre-loaded.

Examples of the type of document that would use Javelin include: an electronic copy of a book in PDF format that has previously been purchased in print or other form via the publisher’s website or a traditional bookstore; notes to accompany a training course; intra-corporate technical manuals; and documents provided on a time-limited basis). Javelin does not support in-app purchasing or direct purchasing of digital content through other means. Advanced catalog-handling facilities provide a convenient means for publishers to provide access to their publications.

Misses the target

Odd double load interface to get PDF into app. Forgets a PDF entirely between opens, so no returning to the page you were just on, and it has to re-render all the previews instead of caching them like other apps. Slow page rendering while it's rebuilding the previews, still not fast when done. Features are an odd collection of stuff, and they feel clunky. I've seen everything it does done better.

The app crashes

The app crashes whenever I try to open a book. List view solves the problem, so I'm changing my rate from 2 to 4 stars.

This app does not work at all. It takes forever to load the pdf you have to wait 30 seconds every time you turn a page and even longer if you used there pitiful highlighting tool if you even want to call it that. DON'T BUY THUMBS DOWN!
