Omnibook Reader: EPUB & PDF

A reader that opens almost anything and gets out of your way.

Omnibook reads EPUB, MOBI, AZW3, KEPUB, FB2, PDF, DOCX, ODT, RTF, TXT, HTML and comics (CBZ, CBR, CB7, CBT). Add a folder and it keeps itself up to date. No account, no ads, no network access: your books never leave your phone.

LOOK UP ANY WORD
Tap a word and it opens in the dictionary app you already have. Works with ColorDict, GoldenDict, Aard 2, Fora, MDict and anything that handles text lookups. Choose once; every lookup after that is one tap.

SCANNED PDFS THAT WORK
A PDF that is only pictures of pages gets its text read off them, on your phone, the first time it opens. After that it searches, selects, highlights and looks words up like any other PDF. Latin and Russian.

READ THE WAY YOU LIKE
Pages that turn, or one long scroll. Light, sepia and dark themes. Font size and line spacing. Volume keys turn pages. A page slider for long PDFs, like Acrobat.

MARK IT UP
Highlights in four colours with notes. Bookmarks. Draw on any page with a pen and eraser, in any colour. Save a PDF with your highlights written into it, so other readers show them.

BUILT TO STAY SMALL
One screen of books, one screen of reading. Nothing to sign up for. Nothing that phones home.

OMNIBOOK PRO
Reading is free, in every format, forever. One purchase unlocks the tools around it: unlimited highlights, drawing, highlighted PDF copies, Russian text recognition, backup and restore, and your own fonts.

• Add files now starts in your Downloads folder.
• A damaged file now says it's damaged, instead of saying the format isn't supported.
