Appendix Books is an app that complements the book reading experience. In the app, the user selects the work he is reading and the page he is on. From there, you can see complementary content to the book, such as character details and author comments. You can also comment on the pages together with your friends - without fear of spoiling, as comments only appear on the indicated page.

The application offers multimedia editorial content that complements the reading, such as: description of the characters, curious facts, places set in the book (real or fictional) and comments (in text and audio) by the author and authorities on the subject. On the platform you can also leave comments referring to specific pages, as well as view the comments of your friends and the general public. All of this content can be shared on social networks - including excerpts from the book, without having to type it out word for word.

Appendix Books is integrated with specific works, in agreement with publishers and authors. When purchasing a physical book or e-book, the user is visually informed that the work is included in the Appendix Books. Through the application, the user scans the book's barcode, synchronizing with the work.
