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.

Subjects, publishers, and a much tidier library. SUBJECTS • Browse your library by subject — pulled straight from your EPUBs, PDFs and comics • Merge variants like "Science Fiction", "science fiction" and "SF" under one name; your choice survives a rescan • Delete subjects you don't want, and optionally remove them from the book files themselves • Pin your favourite subjects to the home screen PUBLISHERS • A section of their own, with every book per publisher and a bit of their history • Merge different spellings of the same publisher under one name • Look up missing details online, just like for authors GETTING YOUR LIBRARY IN ORDER • Add several books at once, or a whole folder or USB drive, with progress you can follow • Let the app find books with missing details and fill them in • Track down damaged EPUBs • Books with more than one author can now be edited, and "Christie, Agatha" counts as one name again READING • The reading controls have been rebuilt: one close button in a fixed spot, a panel that always fits the screen, and a slider that runs through the whole book • The table of contents shows subheadings and actually jumps to the chapter you pick • Your reading position is kept more reliably, even if you close a book quickly or lock the screen • Audiobooks no longer skip chapters BUGS fixed many bugs got flattened in this release, including: • A server address without https:// now works the way the screen promises • Network problems tell you what went wrong, not just that something did • You can send your own HTTP headers, for example for Cloudflare Zero Trust. this is experimental and currently only for the grimmer server option. The layout has been cleaned up too: without a Grimmory server, the options that need one disappear from the menu, and every book now shows where it came from. Plus a long list of fixes for books that vanished, came back, or showed each other's details — and noticeably faster lists.
