Penguin: CBZ Comic Book Reader

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.
- Automatic margin cropping fills the screen with books you scanned yourself.

■ A library in your own folders
- Make folders as you would in Finder, nested as deep as you like, and drag books between them.
- New imports go into the folder you are looking at, dozens at a time, and books move or delete in bulk.
- The folder layout follows you over iCloud. Files are not uploaded, so no iCloud storage is used.

■ Translation that ends on the device
- A speech bubble is read sentence by sentence, translated, and painted back in where the original lettering was. Vertical Japanese is recognized as it is.
- In novels, translate a sentence or a page and read it beside the original, or look up single words.
- Translate a book in advance and pages turn with no wait. Nothing is ever 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 or two-page spread (smart spread), right-to-left binding, single page in portrait.
- 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.

■ Local AI Translation Benchmark
- Measure how fast your iPhone, iPad or Mac translates a page of manga. 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 the score as a PNG card and share it, device name and chip included.
