- 📦Penguin: CBZ Comic Book Reader updated to version 1.9.2Update 1.9.2 - an improvement update that refines how page turns respond with translation on, and how webtoons and the library feel to use.
■ Turning Pages with Translation
· In books you have pre-translated, the speech bubbles on the next page now stay translated even while the page is turning.
· Added “Pre-translate Next Page” to the Translation section of Settings. With it on, the next page is pre-translated while you read the current one, so even in a book you are reading for the first time, you see the translated page as soon as you turn to it. It is off by default.
· Reduced the brief pause when turning the first page after turning on translation.
· Made the translated text in speech bubbles with vertical Japanese text larger, to suit the size of the bubble.
■ Webtoons
· Reduced scrolling stutter when the next chapter is added below and when your reading position is saved.
· Changed the “Recognizing” notice, which often flickered while scrolling a webtoon with translation on, so that it appears only when recognition takes a long time.
■ Library
· When grouping by artist, the app now also reads the author name in a PDF’s document information, and names that differ only in spacing are grouped as one author.
· Fixed an issue where changing the sort or grouping in the middle of a list jumped to the end of the list. The new list is now shown from the top.
· If you lock a folder again while reading a book, the library reflects it right away, even before you close the reader.
■ Wording Across Languages
· Corrected the singular and plural forms of phrases with a number, such as the number of volumes, in English and several other languages.
· Fixed the wording in Komga server book lists, where the page count looked like a page number.

- 📦Penguin: CBZ Comic Book Reader updated to version 1.8.3Update 1.8.3 - adds Change Cover, which you asked for, plus a way to see the update history right inside the app.
■ Change Cover
· I added “Change Cover” to the menu that appears when you touch and hold a book in the library. You can pick an image from the Files app or the Photos app and use it as the cover right away.
· You can switch a changed cover back to the original at any time with “Restore Original Cover” in the same menu.
· With iCloud Sync turned on, changed covers also apply on your iPhone, iPad, and Mac.
■ What’s New
· The first time you open the app after an update, it shows you once what changed in that update.
· In Settings, under “Support · About”, you can see the full update history for every version so far.
■ Fixes
· Fixed an issue where iPhone, iPad, and Mac recognised the same PDF as different books, so your reading position, favourites, and the way you organised My Folders didn't carry over to Mac. Once all your devices are updated to 1.8.3, everything carries over, and the records for your existing PDFs are moved over as they are the first time you open the app after updating.

- 📦Penguin: CBZ Comic Book Reader updated to version 1.8.2Update 1.8.2 - official support for iPhone Duo, plus refinements based on the reports you sent me that make manga and webtoons split into chapters easier to read one after another.
■ Official iPhone Duo support
· The app now uses the entire unfolded inner screen, without the black bars that used to appear above and beside the content.
· In two-page view, the centre seam now lines up with the fold, and I placed the reader's buttons and bars so they don't sit on the fold. Pages stay put even when you hold the device half-folded like a book.
· I reorganised the top buttons into symbol buttons like those in the built-in iOS apps, so the side toolbar also shows each button's symbol and name.
■ Sorting by chapter number
· I improved sorting so titles written with Chinese numerals, such as 第一话·第十二巻, are also sorted in number order.
· I refined the sorting rules so decimal chapters such as 第1.5话, 上·中·下 parts, 前·后篇, seasons and side stories also land in their proper places.
· The same order also applies to books newly added to folders you have ordered yourself and to NAS folder lists.
■ Keep reading with previous and next chapters
· Reach the end and a “Next Chapter” card appears; reach the beginning and a “Previous Chapter” card appears. I improved webtoon mode so these cards also appear right away every time you reach the end or the very top.
· When you go back to the previous chapter from the first page, you can continue from that chapter's last page.
· For series split into chapters, cards and navigation messages say “Chapter” instead of “Book”.
· Numbers that start with #, like “#723”, are now recognised as chapter numbers, and when a long title is shortened at the top of the reader, the chapter number stays visible.
· “Auto-Advance” now keeps going after it moves on from the end of a chapter to the next chapter.
■ “Previous File / Next File” at the bottom of the reader
· I changed “Volume navigation buttons” in Settings to “File navigation buttons”. With it on, you can jump straight from the bottom of the reader to the previous or next file in the same folder, in the order they sit in your library.
· Moving on to the next book or chapter still works from the card that appears at the end. I also refined the card's “Read Now” button to have the same glass look as the other buttons.
■ Fixes
· Fixed an issue where the app could quit if you deleted a book from the library while its tracker connection window or pre-translation confirmation window was open.
· Fixed an issue in webtoon mode where, with auto-trim margins on, the next chapter card didn't appear or the book wasn't marked as finished even after you scrolled down to the last panel.
· Webtoon mode now keeps your reading position better when you rotate the screen or fold and unfold your device.
· Fixed files with % in their names showing under a different name on WebDAV servers.
· Fixed short TXT files under 1,000 characters showing as “0K characters”; they now show the actual character count.
· Fixed the TXT table of contents not finding chapter titles that contain 零·两·万, such as “第一百零一章”.
· Fixed an issue in Smart Two-Page where going to the last page of a book opened for the first time could stop just before the last page, or the “Next Chapter” card could appear before the last spread was settled.
I look forward to your response and your feedback.… more - 📦Penguin: CBZ Comic Book Reader updated to version 1.8.1Update 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.

- 📦Penguin: CBZ Comic Book Reader version 1.8.0Update 1.8.0 - a large overhaul that brings together your many requests and my own ideas.
■ Full iPhone Duo support
· I have added a dedicated interface and a wide range of features for iPhone Duo. I look forward to your response and your feedback.
■ Page curl
· A page-turn effect that naturally follows the movement of your finger has been added.
· I found and fixed a flaw in the existing page-turn structure. In Japanese manga order, the page now turns in the same direction as your swipe and your keyboard shortcuts.
■ Webtoon auto-scroll
· A feature only for webtoon mode: it keeps scrolling even after you lift your finger. I have refined it further.
· Please note that translation in webtoon mode will be fully supported in the next update. Until then I am disabling that feature for the time being.
■ Translation
· Text in speech balloons being cut off or covered has been greatly reduced.
· Translated text no longer overlaps when balloons are crowded on one side of the page.
· I am working to fix translation in webtoon mode as soon as possible. Translation in webtoon mode is temporarily disabled.
■ Settings
· In Settings you can set the reading direction (RtL, LtR, automatic detection) for every book at once.
■ Other fixes
· Fixed the previous page showing for an instant during the page-turn effect.
· Fixed the vertical bar that always stayed on the right when reading webtoons on Mac.… more - 🆕Penguin: CBZ Comic Book Reader released on the App Store

About Penguin: CBZ Comic Book Reader
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.
- Auto margin cropping fills the screen with books you scanned yourself.
■ A library in your own folders
- Make folders like in Finder, nested at any depth, and drag books between them.
- New imports land in the open folder, dozens at a time. Move or delete in bulk, or drag books into your own order.
- The folder layout and book order follow you over iCloud. Files are not uploaded and use no iCloud storage.
■ Translation that ends on the device
- A manga or webtoon bubble is read sentence by sentence, translated, and painted back where the original lettering was. Vertical Japanese is recognized too.
- In novels, translate a sentence or page to read beside the original, or look up words.
- Translate a book 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 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, Two-Page, or Smart Two-Page picking by screen ratio, plus right-to-left binding.
- 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, hiding books from widgets and search.
■ Local AI Translation Benchmark
- Measure how fast your iPhone, iPad or Mac translates a manga page. 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.
