    "How Comical Are You?"


    Comic Viewers come in a variety of tones and styles, but here is one you can count on. With Challenger Comics Viewer, you are provided with a number of tools to facilitate your comic viewing pleasure. With things like multi-touch zoom and simple vertical and horizontal controls, you'll be reading well into the night.


    Challenger Comics Viewer can view apps in a multitude of formats and file types. It is also formatted to play on both smartphones and tablets. The touch controls are responsive and there isn't any noticeable lag when going from one section to another.


    Would be nice if there were more themes and color options in Challenger Comics Viewer. It takes a while for the library to refresh after new content is added.

    Challenger Viewer Donation is an advanced comics, manga, books and PDF viewer.
    There is a FREE version available on Google Play Store.
    The Donation version is exactly the same (no extra features) and donation will help me to improve the app.

    It's really simple to use. You just have to scroll ! Pages are automatically loaded and displayed (no need to click to go to next page).
    This version works perfectly on phones AND tablets.

    Supported image file formats are JPG, PNG, GIF, WebP (Android 4.0+) and BMP.
    Supported book file formats are PDF, CBZ/ZIP, CBR/RAR, CBT/TAR, CB7/7Z, DjVu, and ePUB.

    Main features are :
    • Automatic page loading
    • Zoom using multi-touch
    • Vertical/Horizontal scrolling
    • 2 display modes (Simple View which displays pages one by one and Multiple Image View which displays all pages one after the other)
    • Scale filters: Bilinear, Bicubic, Lanczos4
    • Library with covers displayed to quickly open comics (multiple kind of views available)
    • Automatically switch to next issue when last page of the comic is displayed
    • Border cropping

    • Google Drive
    • OneDrive/SkyDrive
    • Mega
    • Ubooquity (
    • DLNA/Upnp (Need Android >= 4.0.3)
    • OPDS (beta)
    • Windows/SAMBA/CIFS
    • DropBox
    • Webdav/Cloud (like,,, ...)
    • FTP
    • SFTP

    The application needs a phone/tablet with lots of memory and a powerful processor, so don't be disappointed if your phone is quite old and performance is not good.
    For instance, it works perfectly on Nexus 4, Nexus 7, Nexus 10, Galaxy S2, Galaxy S3, Galaxy S4, Galaxy S5, Galaxy S6, Galaxy S7, Galaxy Tab, ...

    Paying is completely optional and you don't lose any functionality if you just use the free version. But absolutely worth it to support a hard working developer.

    Well worth the price, seriously. Yes the free version is identical but the functionality and versatility of the app is worth the money...particularly as you'll have to re-add your comics and books if/when you upgrade.

    Do not update unless you want to set everything up from scratch again. I had a sweet setup and it's reset everything to default. I only wanted the quicker library function. Oh well :-(

    Love this app. I have had no problems loading anything thus far. The plethora of options is a testament to the devs interest in their work. Used other readers and this is my favorite. Happy to spend a few dollars for an excellent tool like this to support someone who cares about users.

    Needs a sort by file path or nested folders.
