Recently changed in this version

Version 2.1.8:
• Improved epub file navigation. You can display table of contents and you can also choose current position using progress bar (using "Goto ..." action)
• Bug fixes

I had some troubles with google, they have suspended the donation version. (it seems I can't do anything).
They probably think the app contains hacked comics.
If you bought donation version, you can use the free version (exactly the same) because the donation version will not be updated. Sorry for the inconvenience.

    Even with a large collection of comics this app has been great. To the Dev I am sorry Google is not allowing you to get paid for your work. If you have a PayPal would love to donate some money for your work

    Slow to load comic. Extracts zips and resize copies in cache folder but appreciate its settings to fine tune memory use

    I was completely skeptical about reading comics on my S4, but I was stunned at how manageable it really is. As a long time user of Comic Book Rack on my computer, this app puts that program to shame. Organization is quick and easy, resizing the page is simple, if you're reading a series the app will automatically mark which ones you've already read, and it saves the page you left off on when you c
