## What is Penguin?

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.
- Enter a nickname of up to 12 characters and 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 the leaderboard are free, with no limit on 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. Only a nickname and a score leave, and only when you post to the leaderboard.
- 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 does not supply manga or novel content. It reads the files you already own.
- Benchmark scores vary with the device and OS state, and move a little run to run.
- The interface is available in 17 languages.

Requests left in reviews get built quickly. Novel reading came out of one.

### 5/5 — 好评

*2026-07-25*

短短1天优化就迅速上线，可以的

**Developer response:** 谢谢好评！改得快，是因为大家的反馈写得具体，问题一下就能定位。更大的更新已经在审核中：从"照片"App 直接导入漫画、封面导入后立刻清晰、侧边栏文件夹拖动排序，都会在下个版本一起到。有想法欢迎随时反馈。

### 5/5 — The translation feature is amazing.

*2026-07-19*

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.

**Developer response:** Hello. Thank you for your kind review.
We are currently aware that the app may lag or freeze in certain scenarios. We are doing our best to ensure the app runs as smoothly and stably as possible. If you continue to experience recurring issues, please contact us at honeybeemobility@gmail.com, as it would greatly help us fix the bugs.
Thank you!

### 5/5 — 意见

*2026-07-19*

能不能在条漫阅读的时候。呼出菜单栏以后 能不能在底部加一个可以拖动的进度条。显示页数的那种。其它阅读模式 底部有进度条

**Developer response:** 感谢您一直以来的反馈！您说得对——之前底部进度条只在翻页模式显示，条漫（竖向滚动）模式下确实没有，也没有任何提示，是我们考虑不周，很抱歉。在即将上线的 1.3.8 版本中，条漫模式呼出菜单后，底部会出现可拖动的页码进度条（显示当前 / 总页数），并与自动滚动控制整合在同一张卡片里，互不干扰、也不多占空间；如果您在「设置 → 页面导航栏」里选择了侧边竖向进度条，现在条漫模式下也能正常使用了。您先前建议的书架网格、底部横向进度条我们都已陆续上线，非常感谢您持续帮助 App 变得更好！如有任何想法，欢迎随时联系 honeybeemobility@gmail.com。

■ 구매와 결제 수리
· 평생 Pro를 구매한 기기에서 네트워크가 불안정하면 무료 한도 안내와 결제 화면이 잘못 뜨던 문제를 고쳤어요. 이제 기기가 Pro 상태를 기억해서 애플 서버에 연결되지 않아도 그대로 유지돼요.
· 구매 복원을 눌러도 반응이 없거나 한없이 기다리게 되던 문제를 고쳤어요. 이제 진행 표시가 뜨고, 이미 구매한 기기는 바로 Pro로 복원돼요.
· 결제 화면에서 가격을 불러오지 못하면 그 사실을 안내로 알려요. 문제가 이어지면 결제 화면 아래쪽에 나오는 진단 코드를 그대로 적어 문의하면 돼요. 어느 단계에서 막혔는지 저희가 바로 확인할 수 있어요.

· 결과는 PVScore 한 점수로 나와요. 숫자가 클수록 빠른 기기예요.
· 결과 화면은 스캔라인이 흐르는 CRT 아케이드 감성이에요. 최고 기록을 넘기면 NEW RECORD가 떠요.
· 점수는 PNG 카드로 저장하고 공유해요. 기기 이름과 칩도 카드에 함께 담겨요.
· 닉네임 12자를 적어 올리면 전 세계 PVScore 상위 500위를 봐요.
