Recent, Library and Folders tabs, reading history, cover grid and list views, and reading statuses from To Read to Completed.

Annotate

Text Mode
Reflow a PDF and read it like an e-book.

Table of contents, links in the file, bookmarks, and jump back or forward through your history.
Safer saving
New in 3.1.0: files are saved more safely, with rescue copies after a failed save.
Private by design
Open source and ad-free, with incognito mode when you do not want a document remembered.
Always back at the right page
The Recent tab puts the book you were reading first, with page count, progress and when you last opened it. Library shows a cover grid you can filter by reading status, and Folders lets you browse your device like a file manager, SD cards included.
- Continue Reading card with progress
- Reading statuses: To Read, Reading, On Hold, Completed, Abandoned
- Search your library from the home screen
Mark up what matters
Select text and pick a highlight color from the bar that appears. The same bar lets you copy, share, search the web, add a note or translate the selection. When a document needs your mark, add a signature or fill in the form.
Every tool is one tap away
Search, Go To Page, Bookmark Page, Full Screen, Hide Margins, Page Text, Print, Add signature, Incognito, Table of Contents, My Bookmarks, My Notes, My Highlights and Text Mode all live in a single menu.
- Jump back, jump forward and navigation history
- Links in the file and file metadata
