What's New in Penguin

1.8.1

October 5, 2026

Update 1.8.1 - fixes and refinements based on your questions and reports. ■ New app icon · I redesigned the app icon. It also fits the Dark and Tinted Home Screen styles. · To keep the old penguin icon, choose “Classic Penguin” under “App Icon” in Settings. · The launch logo and the iPhone/iPad sidebar title, which got cut off, now use the new logo. ■ Set your own book order · Drag books on the shelf into place, or use “Reorder” in the right-click menu (long press on iPhone/iPad), to order books in a folder. · My Folders order syncs across devices via iCloud. Imported Folders order stays on that device and also applies to previous/next volume in the viewer. ■ Webtoon mode translation, fully supported · Webtoon mode translation, temporarily disabled in 1.8.0, is back. · Long vertical images are now read in parts, finding missed speech balloons. · While scrolling, only the panel in view and those just above and below are translated, reducing scroll stalls. ■ Narrower webtoon width · In webtoon mode, pinch in with two fingers to narrow the strip. The width is kept next time. · A new setting locks scrolling vertically, so the view no longer drifts sideways. ■ New features · “Share…” in a book cover's menu sends the book file to another app or device. · In “When the App Opens” in Settings, pick the first screen or reopen your last book right away. · Page through webtoons one screen at a time by keyboard. Auto-scroll keeps going after you drag and let go. ■ Sidebar and shelf layout · Reorder the four sidebar groups (Library, Recent, Imported Folders, My Folders) and your folders. The order is saved per device. · In selection mode, slide a finger across books to select several at once. ■ Imported Folders auto-check · Add books to an imported folder via the Files app or Finder, then open it: new books are added to the shelf right away. On iPhone/iPad you can also pull down on the shelf to refresh. · Books whose originals you delete in Files or Finder leave the shelf automatically. Books on a briefly disconnected external drive or NAS stay, and if many vanish at once, the app asks first. ■ NAS and servers · Fixed NAS (SMB) downloads running to the end even after you chose to cancel. · While a large book downloads from a server, the top-left button closes the screen right away. · If a NAS on the same network can't be reached with a VPN on, the app suggests turning the VPN off. Opening a file renamed or deleted on the server shows a clear message. ■ iPhone Duo and large screens · The “One page at a time in portrait” switch is gone from Settings. “Smart Two-Page” now decides by screen ratio: one page in portrait, two in landscape. For two pages in portrait, choose “Two-Page”. · On wide screens, the viewer's top buttons show their names and sit clear of the fold of an unfolded iPhone Duo. ■ Sync and reading history · Fixed an issue where just opening and closing an EPUB or TXT read on another device reset your position to the start. · Folder changes and Resume from other devices now apply while the app is open, and older records no longer overwrite newer ones. · If the app quits suddenly during a webtoon, your position, recent history and reading statistics are kept. · Mitigated an issue where an EPUB read on another device opened at the chapter's first page instead of your page. ■ Privacy · With App Lock on, widgets, Spotlight search and Shortcuts no longer show book covers, titles or reading progress. · Fixed hidden books briefly appearing in Entire Library when the app was reopened. ■ Mac · With several windows open, notices and purchase windows appeared in each one, and the app could quit while closing them. I fixed this: they now appear only in the window you clicked. ■ Other fixes · In libraries with very many books, the first screen at launch now appears much sooner. As always, I look forward to your reports and feedback.

能否增加个自己更换封面的功能?

如题

软件不错,但有几个bug

首先比较影响体验的点,就算在通用设置里选择了从左往右阅读,在打开漫画时还是会默认从右往左,而且每一本都是,特别折磨;其次,在使用条形瀑布阅读时,开启ai翻译,会直接卡住,建议要么条形阅读时ai翻译只翻译当前阅读的几个页面,反正不能卡住。
总之,软件确实还挺有新意,如果后续能修复这些bug,并继续打磨,就很值得买

Response from developer

感谢您这么详细的反馈,也谢谢您对应用的肯定。这两个问题的原因都在我们这边。 关于阅读方向:导入时,应用会根据文件名等信息把一些漫画自动设成从右往左,这个判断盖过了您在设置里选择的方向。下个版本会改正——设置里选择的方向优先,自动判断只在选择“自动检测”时才生效;同时会新增一个按钮,把您选择的方向一次应用到已经导入的所有漫画。在更新之前,您可以在阅读界面把某本漫画的方向改成“从左往右”,这本漫画会记住这个选择。 关于条形(瀑布)模式下的 AI 翻译:卡死的问题确实存在。我们正按您说的思路修改:只处理您当前正在看的部分,而不是一次处理整张长图。在修好之前,请先在单页或双页模式下使用翻译。 两处修复都还在进行中,完成后会随更新一起发布,请再等一等。如果还有其他问题,欢迎随时联系 krausehaileydanielle@gmail.com。

卡顿

导入漫画数量越多,阅读越卡顿。请改进

Response from developer

谢谢您的反馈,也很抱歉让您遇到这个问题。书越多越卡确实是我们的问题:翻页和打开漫画时,应用每次都会去查询整个书架,书一多就被拖慢。 我们正在修复这一点,会在接下来的更新中发布,请再等一等。更新之后如果还有卡顿,请告诉我们卡在哪里(书架列表还是阅读界面)和大概的本数,我们会继续改:krausehaileydanielle@gmail.com。

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.

Response from developer
