Seems like a great app. I like that I can load a PDFs and write on it. You can connect to Dropbox only though. Only problem is that it takes too long to load each page. I really like the bookshelf look. I would love to use this app in the future when it had improvement.

Almost perfect


First, this is a fantastic cbz comic books and PDF reader. Only this and cloudreaders app are to be considered as a free alternative to reading your own comic books and pdfs. If you are not picky like I am, this app will truly be all you need for reading all of those comic books you have.

I have two nitpick requests that would make the app absolutely perfect. While viewing comics that have some white space behind the page, the background color is grey. For a more immersive experience, it would be wonderful if that could be configured to be black. Second, even though you have the option to set the interval between pages, even the wide interval setting sometimes shows part of the previous and next pages. If this setting could be tweaked so that there is not any of the other pages visible when viewing one page at a time, it would make the app practically perfect.

Aside from those two issues, which are a big deal to me, but probably meaningless to most others, this app does it all. It is one of the best PDF readers for the iPad. It is one of the best digital comic book readers on the iPad. The variety of options for how to view the content is great. The zoom is crisp and clear once you give it a bit of time. The dropbox integration is absolutely seamless. The shelves are fictional and easily organized. In short, this is top notch free software that other are charging for. Do not hesitate to add to our iPad.

Good but could use some improvement


This app does crash more than expected, but there are some key features this app provides that make it worthwhile anyway. The premier features include the passcode lock, so you can use the app for your more sensitive material, and the way that folders can be organized. I love the way folder icons are represented as a collection of book spines (formed from covers of books placed in the folder), how you can set folder-level preferences for how pages turn, and how titles and covers can be edited. However, the app could be improved by a few simple tweaks. First, I'd really like the folder images to be passed up the hierarchy so that the top level book series / folder icon shows the book images from nested folders. Next, if the cover popover setting could include a "set current page as cover" option, that would be awesome (or at least allow us to access the table of contents or file list from this setting). Last, improved sorting by drag and drop (like iBooks) would be much appreciated. I'd like to arrange author shelves, but that's impossible in the current app unless each file is edited so that it begins with the author's name. And even then, single titles and folders cannot be intermingled. Author's works are frequently broken up by shelves of other material, regardless how folders and files are named, simply by placing series in their own folders.
