  1. 5/5The translation feature is amazing.

    It takes a little time, but the on-device translation model easily translates all the speech bubbles in the comic. If you pre-translate the comics when you're not reading them, you can easily enjoy untranslated Japanese manga. The only downside is that the app can be a bit unstable at times.

Versions

App Store

  • 1.1.0
  • 1.2.0

    New in 1.2.0 • Servers and streaming: add a NAS or home server over WebDAV or SMB, or an OPDS library (Komga, Kavita, Calibre). Choose to download everything, or stream and download only when needed — so a library of thousands never fills your device. • Pre-translate a whole book so every page opens instantly, with a translation cache. • Track your reading on MyAnimeList, synced both ways. • In-book bookmarks, auto-trim page margins, and hands-free webtoon auto-scroll. • Your library remembers where you scrolled, and finished books reopen from page one. • Now in 17 languages — added Indonesian, Thai, Vietnamese, Turkish and Arabic, with full right-to-left support. Thanks for reading — your feedback shapes Penguin Viewer.

  • 1.2.1

    Now keep up to 30 books for free! Plus a Launch Sale on Lifetime Pro through Dec 31, with bug fixes and stability improvements.

  • 1.2.2

    Fixed: in webtoon (vertical scroll) mode, tapping the screen now reliably shows the menu so you can return to your library. Thanks to the reader who reported this!

  • 1.2.3

    A cleaner reading screen — the title and page count now stay on one line. Added a clear notice when a translation can't run, quick access to import from a NAS/server right from the home screen, and a Rate the App shortcut in Settings. Plus small refinements and fixes.

  • 1.3.0

    Organize by series at a glance! Comics with ComicInfo now auto-detect their series and author and group together. Stream OPDS servers like Komga and Kavita with no download, and check your continue-reading and streak from a Home Screen widget. Plus ‘Open in Penguin Viewer’ from Files, library backup & restore, and a next-volume shortcut at the end of each book.

  • 1.3.1

    A stability and polish update. • Bulk select & delete during search now applies only to the books you can see • Prevented overlapping imports from running at the same time • Large OPDS libraries now load their full catalog across pages • Image cache now preserves quality more accurately • More efficient widget updates and other small refinements

  • 1.3.2

    This update makes reading more comfortable. • Bookshelf view options — fixed column count, cover size (pinch to zoom), uniform cover alignment • Friendlier translation — progress steps, model download status with retry, first-use guide • Smart double pages: new 'one page in portrait' option (rotate for two pages) • Webtoon auto-scroll labels, first-use tip, and smoother scrolling • Improved info bar and other small refinements

  • 1.3.3

    This update makes reading more comfortable. • Bookshelf view options — fixed column count, cover size (pinch to zoom), uniform cover alignment • Friendlier translation — progress steps, model download status with retry, first-use guide • Smart double pages: new 'one page in portrait' option (rotate for two pages) • Webtoon auto-scroll labels, first-use tip, and smoother scrolling • Improved info bar and other small refinements • Polished purchase flow — restore feedback and more

  • 1.3.4

    Tap the center while reading to open the menu — there's now a draggable page bar along the bottom. • Bottom progress bar — drag to jump back or ahead with page numbers (e.g. 10/100) and a preview while dragging • Choose the bar style in Settings: bottom (horizontal) or left/right (vertical) • Restore-purchase and payment feedback, plus small refinements

  • 1.3.6

    Polished the reading screen. • Webtoon auto-scroll is now much smoother, synced to your display's refresh rate (120Hz supported) • The top menu bar now extends naturally to the very top of the screen • The bottom page bar is slimmer so it covers less of your comic • New 'Support us' — share the app with a friend and get +10 free books as a thank-you (Settings)

  • 1.3.7

    This update refreshes our App Store page and polishes small details throughout the app. Happy reading!

  • 1.3.8

    Webtoon (vertical scroll) mode now has a progress bar. Open the menu and it appears at the bottom, sharing a card with the auto-scroll control—drag it to jump to any page, with your current and total position in view. The side progress bar from Settings now works in webtoon mode too, along with small refinements. Thanks for asking for this.

  • 1.3.9

    Page turns now have a look you choose — none, slide, fade, or page curl, with slide as the default. Two-page view gains a single-page advance, so you can shift the spread by one when a cover throws the pairing off. Auto-scroll finally uses the full refresh rate on ProMotion (120Hz) iPhones and holds a steady speed even when a frame slips; on Mac it follows your display. With Reduce Motion on, the effects ease off by themselves.

  • 1.4.0

    Someone wrote in to say imported images looked blurry, especially long vertical webtoons — pages were being drawn far smaller than the screen could show. Pages now use the resolution your display actually has, so long webtoons keep their full width, and zooming reloads the page at a higher resolution instead of stretching a shrunken copy. Covers on the shelf are sharper too, and large images are easier on memory. Thanks for the report that led us to it.

  • 1.5.0

    New: import comics straight from the Photos app. Pick an album and its photos become one book in album order, copied at original quality and processed only on your device. If you would rather not grant photo access, there is also “Pick Photos to Import”. The feature came from a user's suggestion. The entries under “Imported Folders” in the sidebar can now be dragged into any order you want (on iPhone and iPad, press and hold, then drag). Fixed on Mac: with comics in your Library, the app could freeze or quit right after launch. Tidying up the Library while a comic was open also left the reader window black. Other fixes: covers of newly imported books stayed blurry, image folders you imported directly never showed up under “Imported Folders”, and two folders with the same name were merged into one (they are now told apart by path). Thanks to everyone who reported these.

  • 1.5.5 · 5 Aug 2026

    Novels and text books are here — this update comes from your requests and reports. • Read novels and text books — import TXT, MD and EPUB files and read them. Font, text size, line spacing, margins and background color are in “Text & Layout” at the top of the reader, and chapters are in “Contents.” Your reading position and bookmarks carry over. • Translate as you read — select a sentence or translate the whole page on your device and read it next to the original. Word meanings come straight from the dictionary. • Pinch to zoom in Webtoon — zoom with two fingers in vertical scroll and drag while zoomed in. • Switch books anytime — tap the page and the previous book and next book buttons are always there. • Better search — search runs on the search button or Return, so typing stays smooth in a large library. • New reader design — top, bottom and side controls share one floating glass style. • Page Order — if the file names are capture codes and the pages come out shuffled, set “Page Order” to “By Date Modified.” Position and bookmarks follow the same pages. • PDF quality — PDF comics render at your screen's resolution; PDFs from photos keep their original quality. • Show time left — how long is left in this book, from your reading speed. • Reading Calendar — look back on which days you read, and how much. • Auto Night Theme — at the hour you set, the reader background turns black. • View settings preview — change a value and see the result right away. Thanks for every report and request. We're still listening.
