This was my favorite comic viewing app, but trying to zoom in (for example, on double pages, which are downscaled to fill the screen) will result in extremely degraded and pixelated images, rendering some books unreadable no matter what you do. The option to display images in high resolution does not work and reverts back to "medium" (in reality, extremely low) quality as soon as you exit the app. It's perfect in every other way, but this bug is serious enough to break the entire experience.

"Google drive" is hidden behind "Open Web". Google Drive is not a website. I never tried it since I wasn't trying to open a comic from a website, but rather from my drive. There are a number of very, very basic UI expectations which are hidden; to select a directory to upload to a new comic book library, you have to long-select any individual file in the directory you wish to add and wait for a pop-up to ask you if you want to use the whole directory. The app is functional but has some fundamental UI/UX issues.

To open a Google drive file, you should use "Open Web" action and then choose "Open Drive". To add folders to library, you should use "Add Web" action and then choose "Add Drive folder". About file associations, depending of you Android version/Device, third party applications (not pre-installed on device) can be unable to register file association

It is very reliable but lately it has been showing my library in double. Not sure why. Going to try to reinstall. There should be a few more perks added to it to make it better. Like a guided view would be cool. Not sure what else to round it off, maybe some updated feel to the user interface; then it has the potential to be the best comic reading app. I would even pay or donate for an improved version
