BookMapper is a one-of-a-kind app, as there is no other tool that does what it does.  If you frequently work with PDF ebooks in your study or job, BookMapper can help you become more productive by giving you a new level of power over how you interact with your books.

What makes BookMapper unique:

1)  Highly-responsive page-flipping to simulate physical books, which enables you to browse the book rapidly in a visually comfortable way.  This greatly increases your sense of navigational control over the book, compared to the ubiquitous page-scrolling method of other PDF readers,

2)  All the standard PDF tools (bookmarks, table-of-contents, search, etc) are presented in a popup layer so that you can browse their pages WITHOUT affecting your reading layer.  This ensures that you do not have to switch away from your current reading page whenever you need to view the pages associated with the PDF tools, unlike other PDF readers.

3)  When you are reading your book, and encounter a reference to a figure located somewhere else in the book, you can click the reference to automatically popup the page to display the figure.  You do not need to manually browse the book to locate the figure, and causing you to lose your current reading page.

4)  When you are reading an academic paper, and encounter a citation to an item in the references list of the paper, you can click the citation to popup the item.  You do not need to manually scroll to the references list, and causing you to lose your current reading page.

5)  When you perform a search on your book, the search results will not be replaced when you later perform another search.  This allows you to retain multiple sets of search results, which is useful when you need these different results to be simultaneously available to support your work.

6)  BookMapper remembers the page you were reading so that whenever you return to the app, any book you open will automatically open at the previous page you were viewing during the last BookMapper session.

7)  If your book is a textbook containing an Index section, BookMapper can turn the Index section into a powerful tool where you can simply click on an index item to popup the set of relevant pages mentioned in the item.  This allows you use the Index section to browse for relevant pages, without losing your current reading page.

8)  BookMapper lets you annotate beyond the traditional page-level annotations:  You can use “maps”, which are documents at a higher-conceptual level, to express whatever additional information you want about your page-level annotations.  Using this approach, you can create higher-level annotations that span across multiple PDF files, which is something you will appreciate when you need to capture notes involving multiple research papers, for instance.



When you open a PDF file with BookMapper, the book that is created from that file will expire after 30 days.  After the book expires, you can delete it and re-open the same PDF file to create a new book to continue reading it if you wish.  However, any maps you might have created for the deleted book would be lost.  If you decide to keep the maps you have created for that book, then instead of deleting the expired book, you need to remove its expiration so that you can continue working on its maps.  Removing a book's expiration requires a subscription via in-app purchase.  

If you are not planning to use maps, then subscription is not necessary, and you can simply use BookMapper as a preferred PDF reader because of its sheer power over conventional PDF readers.  After you have personally experienced these unique strengths of BookMapper to read your PDF files, you will find it hard to return to using conventional PDF readers!
