The app has an unusual interface that ultimately is no better than the standard iOS way of doing things, but *is* confusing.
The big problem with this app is that it offers almost no options for importing comics. Its iTunes or the devs website. No Dropbox, no WebDAV, no SFTP.
The only way to get comics into the app when youre not tethered to iTunes (and who is these days?) is to download them with an app that does understand how to import data and open them one by one with ComicZeal.
