Your books. Your library. Your way. Privacy By Design. Made in the EU.
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.
Ratings & Reviews
This app has not received enough ratings or reviews to display an overview.
NEW
• Authors by country: every author profile shows their country with its flag, in the app's language – and all of them for authors with more than one nationality. Countries that no longer exist, such as Prussia, are listed too.
• Filter authors by country: tap the globe next to Sort in Authors to see only the authors from one country.
• Enrich authors: under Library management, three steps in one place – Link to Wikidata, Fill in details and Add countries. You first see what was found (Certain, Uncertain or Not found) and only what you approve is saved.
• Select several books under On this device and delete them all at once.
• Comics downloaded from WebDAV can now be deleted from this device only.
• Rate Grim Reader from Settings.
IMPROVEMENTS
• Cover search finds more results: title and author are now searched separately.
• Photo search looks further on Wikidata and Wikipedia and only shows real photos.
• The author list scrolls smoothly, even in a library with thousands of authors.
BUG FIXES
• The page number in EPUB books no longer jumps when you start a new chapter: every page turn now moves exactly one page on.
• Text stays readable with the System theme: books that fix their text to black or white no longer disappear in dark or light mode.
• Details and photos you added to an author yourself are no longer replaced by an online search.
• Countries you pick for an author are now saved.
• CBR comics from a WebDAV server now get a cover.
• On iPhone Duo, book text no longer runs under the side bar.
Grimmory
• Works with any Grimmory account, including users without admin rights, and is ready for Grimmory's new API.
• Large audiobooks from your server start playing right away again, without timing out.
• Your Grimmory account needs at least download permission to open and read books.
Grim Reader is made by one developer in spare time. If you like the app, a review in the App Store helps more readers discover it. Thank you!
