Grim Reader

Grim Reader is a fast, privacy-friendly e-reader for your own books. It started as a reader for your self-hosted Grimmory library and grew into one app for all your books — no account, no cloud of ours, no tracking. READ FROM ANY SOURCE • Grimmory — connect to your own server and browse libraries, series, authors and shelves. • OPDS — discover over 70,000 free public-domain books from Project Gutenberg. • WebDAV — open the EPUBs, PDFs and comics already stored on your NAS or cloud. • Your own files — add individual EPUBs and PDFs via "Open with …", with no server at all. EVERY FORMAT • EPUB in a full-screen paginated reader • PDF • Comics (CBZ/CBR) • Audiobooks LIVE TRANSLATION — ON YOUR DEVICE Reading a book in a foreign language? Tap translate and Grim Reader translates exactly the page you're reading into your own language. Entirely on your iPhone or iPad, with no text ever leaving for a server. After a one-time language-pack download it works offline too. (Requires iOS 18 or newer.) BUILT FOR EVERYONE • Meets WCAG 2.2 level AA • Dynamic Type: font size, typeface and line spacing to taste • Light and dark contrast that follows your system • Full VoiceOver support • Read aloud, with the spoken sentence highlighted and scrolled into view OFFLINE AND YOURS Download your books and read them anywhere, even without a connection. Your server address and login sync securely via your iCloud Keychain to your other Apple devices, and stay encrypted on your device. PRIVACY BY DESIGN Grim Reader collects no data, contains no ads and no tracking. The app only talks to the server you set up. Your books stay yours — right down to translation that never leaves your device.
