What's New in Penguin Viewer

1.5.5

August 5, 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.

好评

短短1天优化就迅速上线,可以的

Response from developer

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。

The 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.

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

Response from developer

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。
