Works with VoiceOver. • Open password-protected PDFs; the app can remember the password if you like. • Chapters in your own M4B and MP3 audiobooks. IMPROVED • More reading settings: margins, letter spacing, word spacing, alignment and bolder text. • Books in Arabic, Hebrew and other right-to-left languages turn pages in the right direction. • A clear message for DRM-protected or damaged files. • If a cover is missing when looking up book details, the app finds another one. • Better stability.

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.

Grim Reader now makes full use of the foldable screen. Lists and details sit on either side of the fold, half-open shows the same screens as fully open, and you keep the familiar five tabs. Books read in two columns, one on each half. Also new: • The reading menu now hides by itself after four seconds without a touch – in books, PDFs and comics. It stays put while a panel, the table of contents or the page grid is open, or when VoiceOver is on. • EPUB books now show two columns by default on iPad in landscape. Turned it off yourself? Then it stays off. • Pressing play on an audiobook now opens the Listen screen straight away. • Comics now have their own icon, so you won't mix them up with Series. • More text translated. ### 1.6 — 2026-10-22 New - Delete now works the way you expect. A book's More menu now has "Delete from this device". For a book from your WebDAV server you can also choose "Delete from device and server". If it's your own import, the app warns you first. - More than one author when editing in bulk. When you edit several books at once, you can now give them multiple authors too, such as a writer and an illustrator.

If your iPhone or iPad is set to German, the whole app now speaks German. - CBR comics. Import a CBR, or open one from WebDAV or your own OPDS catalogue. The app converts it once, and from then on it reads like any other comic. - Manga reads right to left. A comic marked as manga turns its pages the right way automatically. You can also choose the reading direction for each book. - Reading stats. Under Settings you can see how much you read and listen: your reading time per day and per month, your most-read authors and formats, and your reading streak. Everything stays on your device. - One calm reading menu in every reader. EPUB, PDF and comics now share the same compact floating bar with bigger buttons. Close panels with the close button or by swiping down. - Choose your read-aloud voice. Pick a voice for each language, or let the app pick the best voice on your device. Play and pause now share one large button. - Footnotes in a popup. Tap a footnote and the note appears over the page, and you keep your place. - Audiobooks from your OPDS catalogue, including books in several parts. If a download is interrupted, it picks up where it stopped. - Sort and filter the way your catalogue offers, such as Newest or Popular. - Sharper comics. Turn on "Sharpen" to make low-resolution scans look crisper. Improved - A new read-aloud voice applies straight away, even if you change it while paused. - Comics that were wrongly reported as "too large" open again. - Books that are only for sale or for loan are no longer offered as downloads. - A downloaded PDF keeps its cover. - Plus many smaller fixes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
