SideBooks is a general purpose reading app that can display file formats beyond just CBR, CBZ, and PDF. Perhaps unsurprisingly, the app is not as proficient at rendering comics as the dedicated comics reader apps. SideBooks does a competent job displaying the comic files and includes an in-app connection to Dropbox and a few other desirable features. Side Books’ main flaw is a failure of navigation—the app doesn’t integrate zooming into and out of pages very well.

App Store Description

*2017/06/13 About Freeze at Dropbox Authentication
A freeze problem was confirmed in an environment that simultaneously satisfies the following two conditions.
· Other than MAX is set in SETTINGS > BRIGHTNESS of SideBooks.
· Dropbox application is not installed.

· Set the brightness to MAX with SideBooks setting.
· Install the Dropbox official application and login.
Either method can be avoided.

We will respond to this trouble at the next version upgrade.
We apologize for any inconvenience.
