Grim Reader is a modern reader and library manager for e-books, comics and audiobooks. Keep your collection on your device, connect to your own servers, and turn even a simple collection of files into a rich, beautifully organised library.
A library that feels alive
Browse your collection by books, authors, series and more. See covers, reading progress and detailed information at a glance, continue where you left off, mark favourites and quickly find what you want to read next.
Grim Reader is designed for both iPhone and iPad, with an interface that adapts to the device you are using.
Enrich your books
Missing a cover, description or other information? Grim Reader can help enrich your library using online book and author sources.
Depending on the available information, Grim Reader can help you find and add details such as:
• Covers and book descriptions
• Authors and author information
• Series information
• Publisher and publication details
• ISBN and other identifiers
• Genres, categories and tags
• Additional book metadata
You remain in control and can review and edit your library information.
More than e-books
Grim Reader brings different types of reading together in one library:
• Read e-books
• Browse and read comics
• Listen to audiobooks
• Keep track of reading progress
• Continue reading or listening across your library
• Organise books by author and series
• Mark books and authors as favourites
Your files, your servers
You don’t need to hand your library over to a commercial book platform. Grim Reader can work with books stored locally and supports personal libraries through WebDAV and OPDS, as well as the optional Grimmory server.
This makes Grim Reader equally useful for a small collection on your iPhone or iPad and for a large self-hosted library.
Made for readers
Grim Reader focuses on your books rather than a store. There are no books to sell you and no ecosystem you need to buy into.
Build the library you want, enrich it, organise it and enjoy reading it.
Grim Reader — your library belongs to you.
