Comic Reader CBR, CBZ & PDF screenshots
ComiQuest is a comic reader for Android from Mad Mustache Company, built to open the three file types most digital comic collections arrive in: CBR, CBZ and PDF. It sits in the Comics category on Google Play, has passed 100,000 installs and holds a 3.7 average from 713 ratings. The app is free to download, carries no ads, and offers in-app purchases.
The case for trying it is straightforward. If your comics live as files rather than inside a storefront or subscription service, you need something that recognizes those formats, remembers where you stopped and lets you arrange a library without fuss. ComiQuest sets out to do exactly that, and it does so without interrupting the page with advertising. That combination is the reason to consider it.
Reading CBR, CBZ and PDF files without converting
The core of the app is format support. It opens CBR, CBZ and PDF files, which covers the bulk of what you are likely to have collected over the years, whether that is scanned issues, digital single issues or full graphic novels. The developer's pitch is that you can read your collection without converting files or switching between apps, and for anyone with a mixed folder that is the main draw.
That mix matters more than it sounds. Plenty of readers handle one format well and treat the others as an afterthought. Here the three formats are supported, so a PDF art book and a CBZ volume can sit in the same library. I would expect this to appeal to readers whose collections grew organically, pulled together from different sources over time rather than bought in one place.
The app is described as being for manga, manhwa, webtoon and graphic novel fans, which is a broad church. Format support is what unites them; the reading material itself can be anything from a long-running serial to a one-off volume.
Progress tracking that follows each title
Reading progress is tracked automatically for every title and format, so closing the app mid-chapter and coming back later should return you to roughly where you left off. For serialized reading, where you might be partway through several series at once, this is the feature that decides whether an app is usable or annoying.
A long-running manga and a short PDF issue each keep their own place. That is the behavior I would want from a reader: open the app, tap a cover, continue.
It is worth thinking about how much this matters to you. If you tend to finish a volume in one sitting, progress tracking is a convenience. If you read several series in parallel, or in short stretches, it is closer to essential, and it is one of the stronger arguments for keeping your library in one app.
Collections that keep a large library navigable
ComiQuest lets you sort comics into custom collections, so a library can be grouped by series, genre, author or whatever scheme you already use. The developer mentions graphic novels, manga and webtoons as examples of what those collections might hold, but the grouping itself is up to you.
This is the part of the app that matters once a collection grows past a few dozen files. A flat list of covers gets unwieldy quickly, and custom collections are the usual answer. How many collections you can create depends on whether you are on the free version or have paid for the premium upgrade, which the developer lists as including unlimited custom collections alongside unlimited imports of CBR, CBZ and PDF files.
The premium tier is also where continuous feature updates and ad-free access are grouped. Since the app already carries no ads, the practical difference for most readers will come down to how many files they import and how many collections they want to build.
Importing files and the blue light filter
Getting comics into the app is done by importing them from local storage or from a USB drive. The developer describes the process as recognizing and opening files without extra steps, so the expectation is that you point the app at your files and it reads them.
The app also includes an experimental blue light filter intended to reduce eye strain during longer reading sessions. It currently works for CBR and CBZ files, so PDF reading does not get the same treatment. If you read late in the evening and rely on a warmer screen, that distinction is worth remembering.
The most recent update is a maintenance one: it fixes crashes that could occur when scrolling a collection, when a library or collection became empty after deleting the last item, and shortly after deleting a book. The download size on Android was reduced as well. None of that changes what the app does, but it suggests attention to the everyday stability of library management.
Who will get the most from ComiQuest
This app is built for readers who keep comic files rather than stream them: people with folders of CBR and CBZ archives, PDF issues and art books, and a preference for reading them on a phone or tablet. If your library is already organized on a drive and you want an app that opens it as-is, the format coverage and the import route from local storage or USB are the relevant strengths.
It also suits readers juggling several series at once. Automatic progress tracking per title and custom collections are the tools that make a large, mixed library manageable, and both are central to what the app offers.
The free version comes with limits on imports and collections, so the premium upgrade is the route to an unrestricted library. Anyone with a modest collection may never notice those limits; anyone with hundreds of files should factor the upgrade into their decision.
A reader for file-based comic libraries
The absence of ads and the ability to import from local storage or a USB drive make it easy to point at a library you already own. For readers whose comics exist as files, that is a coherent and useful package.
The caveats are modest but real. Imports and custom collections are capped unless you pay for the premium upgrade. And the app's rating sits at 3.7, which is not a ringing endorsement from the install base so far.
If you have a folder of comic files and want one app to read them without converting anything, ComiQuest is worth installing and trying against your own library. If your reading happens inside a storefront or subscription service, this app has little to offer you.
The short verdict
A focused, ad-free reader for people whose comics live as CBR, CBZ or PDF files, with paid upgrades for larger libraries.
