AOJ Reader is a PDF reader for those who read carefully and like to leave their mark on the page. It displays the book exactly as it is, without adding or removing anything, and places a layer over it for highlighting. Your margins are kept separate, so the book file remains untouched.
A Library on Shelves
• Add your books from your device's files, one book or several at a time.
• The books are arranged on wooden shelves, each displaying its first page.
• Organize them into groups, and each group into subgroups, with a bar to guide you to your location.
• "Recently Opened": The most recently opened books in one place.
• Select multiple books to move or delete them together, and share any book with another application.
Comfortable Reading
• Horizontal or vertical browsing.
• Three paper colors: white, a calming yellow, and dark for nighttime reading.
• Crop white margins to enlarge text on small screens.
• The book takes you back to your last page.
• Bookmarks, table of contents, and a list of everything you've highlighted.
• Works in portrait and landscape modes, on mobile and iPad.
Highlight and Annotate
• Highlight, underline, and strikethrough in four colors, and a freehand pen.
• Write your notes on any highlight.
• Undo your last action and erase unwanted sections.
Your Books on Your Devices
• Link Google Drive — if you wish — to sync your books, highlights, margins, and last read page across your devices.
• Your copy is saved in your Google Drive space, in the app folder only. The app does not access your other files.
• The app works completely on your device without an account.
Your Privacy
• No ads, no tracking, and we don't collect any of your data.
Your books and annotations are on your device and in your account if you choose to sync.
Arabic interface, also available in English.
