Penguin: CBZ CBR Comic 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.

■ Untranslated novels in your language
- Tap 文 at the top of a TXT or EPUB novel to read it translated. Tap again for the original.
- The book's language is detected, and it translates to your device language or one you pick.
- See the original under each paragraph, or long-press a paragraph for it.
- Translated on the device. Your book is never sent anywhere.
- Page curl turns pages like paper, with two-page spreads on wide iPad, iPhone Duo and Mac screens.
- Vertical Japanese EPUBs turn page by page.

■ Manga and novels in one library
- Drop in CBZ, CBR, CB7 (7z), ZIP, RAR, PDF or an image folder. TXT, MD and EPUB novels share the shelf.
- Auto margin cropping makes your own scans fill the screen.

■ A library in your own folders
- Nest Finder-style folders at any depth and drag books between them.
- Import dozens at once into the open folder. Move or delete in bulk, or drag books into any order.
- Folders and book order sync over iCloud without uploading files or using iCloud storage.

■ Translation that ends on the device
- Manga and webtoon bubbles are translated sentence by sentence and relettered in place, vertical Japanese included.
- In novels, tap 文 to read the book translated, or look up words.
- Translate a whole comic 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 streams from your page with no download, so huge libraries take no storage.
- Reading position syncs over iCloud. Server credentials stay in the keychain.

■ Read it the way you want
- Single Page, Two-Page, or Smart Two-Page by screen ratio, plus right-to-left binding.
- Webtoons scroll vertically or auto-scroll at 120Hz. Pan sideways while zoomed in.
- Multi-gigabyte volumes turn smoothly. Pinch zoom works in spreads too.
- A scheduled night theme blacks out the reader. 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 device translates a manga page and get a PVScore.
- Save and share the score card, and join the global top 500 leaderboard.

■ Honest pricing
- Almost everything is free. The free library holds 30 books, plus 10 for sharing the app.
- The benchmark and leaderboard are free, with unlimited runs.
- Unlimited library: one lifetime Pro purchase, no 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.
- 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 own.
- The interface comes in 17 languages.
