A comic reader for the books you already own. CBZ, CBR, PDF and EPUB open straight from Files, your Mac, or your NAS — no unpacking, no account, no ads, and no internet needed once a book is on the device. Japanese pages you cannot read? Penguin Viewer translates the speech bubbles on your device and paints the English back into the balloon. ■ Manga and novels in one library - Drop in CBZ, CBR, CB7 (7z), ZIP, RAR, PDF or an image folder. TXT, MD and EPUB novels land on the same shelf. - Auto margin cropping fills the screen with books you scanned yourself. ■ A library in your own folders - Make folders like in Finder, nested at any depth, and drag books between them. - New imports land in the open folder, dozens at a time. Move or delete in bulk, or drag books into your own order. - The folder layout and book order follow you over iCloud. Files are not uploaded and use no iCloud storage. ■ Translation that ends on the device - A manga or webtoon bubble is read sentence by sentence, translated, and painted back where the original lettering was. Vertical Japanese is recognized too. - In novels, translate a sentence or page to read beside the original, or look up words. - Translate a book in advance and pages turn with no wait. Nothing is sent anywhere. ■ Read novels your way - Font, size, line spacing, margins and background change in Text and Layout, live. - Jump chapters from the contents. Position and bookmarks carry between devices. ■ Your NAS and server library - Connect over SMB (NAS), WebDAV or OPDS, compatible with Komga and Kavita. - OPDS-PSE streaming resumes at your page without downloading, so a huge library takes no storage. - Reading position syncs over iCloud, and server credentials stay in the device keychain. ■ Read it the way you want - Single Page, Two-Page, or Smart Two-Page picking by screen ratio, plus right-to-left binding. - Webtoons scroll vertically, or run 120Hz auto-scroll through a binge. Pan sideways while zoomed in. - Multi-gigabyte volumes turn without stutter, and pinch zoom works in spreads too. - A night theme blacks out the reader on your schedule, and Mac turns pages from the keyboard. ■ A library that sorts itself - Smart shelves file books as unread, reading or finished, and ComicInfo groups a scattered series. - Set grid columns and cover size, sort by recently opened, search by title, author or series. ■ A record that grows as you read - Reading statistics, streaks and milestones build the habit. - The reading calendar shows how much you read, iOS widgets show today's, and Face ID locks the app, hiding books from widgets and search. ■ Local AI Translation Benchmark - Measure how fast your iPhone, iPad or Mac translates a manga page. Run it from Translation in Settings. - The result is a single PVScore. A bigger number means a faster device. - The results screen is CRT arcade, scanlines and all. Beat your best and NEW RECORD appears. - Save and share the score as a PNG card, device name and chip included. - Enter a nickname (up to 12 characters) to see the worldwide PVScore top 500. ■ Honest pricing - Almost everything is free. The free library holds 30 books, and sharing the app opens 10 more. - The benchmark and leaderboard are free, with unlimited runs. - An unlimited library is one lifetime Pro purchase, not a subscription. No ads anywhere. ■ Privacy by default - Local first: files, translation, statistics and benchmark results stay on the device. - Leaderboard posts send nickname, score, run log and device info (model, chip, RAM, OS), all shown first. - Linking MyAnimeList sends it your title searches and volumes read. - No account, no sign-up, not a single tracking SDK. Open it and read. - Export your library and reading history, and restore it on a new device. ■ Good to know - Penguin Viewer supplies no manga or novels. It reads files you already own. - The interface comes in 17 languages. Requests left in reviews get built quickly. Novel reading came out of one.
