Chunky: A Native Comic Reader for CBZ, CBR, and PDF Libraries

Chunky is a native comic and manga reader for people whose digital library has outgrown a handful of files. It opens CBZ, CBR, and PDF, groups books into series, tracks reading progress, and connects local collections with iCloud or remote servers. The current App Store listing is free and covers iPhone, iPad, and Mac; the source repository also contains a tvOS target, with a platform caveat worth noting.

Build a library for long comic series

Instead of treating every archive as a separate download, Chunky can group books by series and show favorites plus unread, in-progress, and finished states. Sections for new books and what you are reading make a large collection easier to revisit.

The reader handles CBZ and CBR archives, PDFs, and folders of loose scanned pages. You can bring in a folder of images and turn it into a comic, while a library-rebuild tool is available for recovering from an imperfect restore. This organization suits ongoing series and mixed collections more than a one-off document viewer, keeping a reading shelf navigable as the number of volumes grows.

Tune page layout and reading direction

Read left to right or switch a book to manga-style right-to-left. Pages can appear singly or as double-page spreads, automatically or manually, with an option to keep the cover on its own.

Page turns can feel instant, sliding, or cross-faded, with separate settings for taps and swipes. One-handed mode and hot-corner shortcuts help move through a book without repeatedly opening the reading controls.

Make scans easier to read

Chunky can automatically crop scan borders, adjust tint and contrast on yellowed or faded pages, and upscale low-resolution images. Zoom options include fit-page and fit-width, with a scrollable width view for tall pages.

Light, dark, and sepia page themes, plus motion blur while panning a zoomed page, let you adapt the reading surface. These are image-viewing tools rather than a promise to repair every source scan; the quality still depends on the original pages.

Keep a library in sync with iCloud

On supported Apple devices, iCloud can keep the library in sync. A Sync Folder workflow also lets you place comics in iCloud Drive and have them appear in Chunky without importing each file again by hand.

Downloads show progress, and the project describes smart downloading to manage books across devices. iCloud sync depends on your Apple account and available iCloud storage; it is separate from the reader’s ability to open files stored locally.

Connect to remote comic libraries

Chunky can connect to WebDAV sources such as a NAS, Nextcloud, or ownCloud, as well as OPDS catalogs such as Calibre or Ubooquity. The README also lists SMB support for shared folders.

For a nearby transfer without a cloud account, a local upload server lets you send comics from a browser on the same Wi-Fi network. These source options are useful for a home library, but remote access depends on the server, network, and any credentials you configure.

Share a panel instead of a whole page

A panel or region selector can share one part of a page without sending the entire page, useful for discussing a detail while keeping the rest out of the crop. Chunky also includes a parental lock protected by a code and Face ID or Touch ID, plus a kiosk mode with an idle-reset timer for shared devices or displays; the code is described as never being stored in plain text.

Understand what the App Store listing covers

The exact Chunky App Store listing is published by Scunio SRLs and identifies the app as com.scunio.Chunky, matching the repository’s developer and product. Apple currently lists it as free, with iPhone and iPad support from iOS/iPadOS 17 and Mac support from macOS 14; the store showed version 1.0.1 at research time.

The GitHub repository has a separate tvOS target, but Apple’s listing checked here shows iPhone, iPad, Mac, and Apple Vision—not Apple TV. Do not assume the same App Store link installs a tvOS app. The listing’s language field is English, and its privacy label says the developer reports no data collected; Apple notes that this disclosure is not independently verified.

Privacy and open source have clear boundaries

The README says there is no required Chunky account, no tracking, and local-only crash diagnostics through MetricKit. The App Store privacy label likewise reports no data collected, while making clear that the developer supplied the information and Apple has not verified it.

iCloud sync, remote WebDAV/SMB/OPDS sources, and the local upload server still involve the Apple or server connection you choose to use. That is different from the app collecting analytics, but you should still consider your iCloud settings, server logs, and credentials when connecting a private library.

Chunky is a from-scratch SwiftUI rebuild of an earlier iOS-only app, now organized as separate iOS, macOS, and tvOS targets. The repository is MIT-licensed, and its documentation lists ZIPFoundation and Unrar.swift as MIT-licensed dependencies.

That makes the source available for inspection and contribution, while the App Store remains the end-user installation route. If you need Apple TV, verify that a compatible tvOS app is actually available before relying on the repository target alone.

Install Chunky from the official App Store

For a ready-to-use build, start with the official free App Store page for Chunky. Apple identifies the seller as Scunio SRLs; the listing names the same app and supports iPhone, iPad, and Mac.

The current compatibility details require iOS 17 or later, iPadOS 17 or later, and macOS 14 or later. The repository also contains a tvOS app target, but Apple TV compatibility is not shown on this listing. The App Store page displayed version 1.0.1, dated August 17, 2026, when checked.

The App Store is the verified installation path; the repository does not publish a GitHub Release installer. To open the exact store page in your browser or App Store app, use:

Who will get the most from Chunky?

Chunky is aimed at readers with a growing collection of comics or manga who want series grouping, reading progress, flexible page layouts, and a choice between local files, iCloud, and remote sources. The scan controls and manga reading direction make it more tailored than a general PDF viewer.

It may be more than you need for occasional PDFs, and Apple TV remains a separate availability question despite the repository target. If your devices meet the listed OS requirements, the free App Store version is the simplest place to start.
