    I was already disappointed with how many permissions the app needed. Just uninstalled it after it started asking for another.

    Near perfect, interface needs work looks fairly ugly, but the ease of scrolling is amazing

    I'm always searching for a mangareader with scrolling as reading option and this really the best choice! I've tried other apps and until now no apps can satisfied me other than this. Thanks!

    No ads, absolutely free. Encountered a small bug, the developer responded with a fix within hours.

    One of the smoothest reading experiences i have had with a comic reader. An option to change image orientation by image size would be nice but otherwise pretty much perfect.

    It could pull files directly from my dropbox, which was amazing, but it couldn't scroll without scrolling continuously, and the screen wouldn't lock even if my screen lock was on, making it hard to read in bed. I'm almost looking for something simpler to want these features.
