Those books on "cloud" bookshelf are books prepared by volunteers and supporters, which include public domain PDF books optimized for iPad screen as well as free or sample publications provided by authors and publishers.
If you are interested in participating to this "cloud bookshelf" effort, please contact email@example.com (or just send PDF files).
Rebuilt for latest iPhone, iPad and iPod touch.
Ratings and Reviews
Difficult to navigate
I found it to be too 'springy' when sliding my finger back and forth to read comics when zoomed in. If I swiped too far, it went to the next page too easily. Then when I swiped back, it would go to the to the top left corner, not back to where I was. I found I had to be too careful sliding the page around to stay on one page. Maybe an option to 'tap only and not swipe' to go to the next page. Mark.
Excellent archive reader
I especially love it for picture archive files. The images aren't resized relative to each other, and it doesn't force images to fit into a single "page" like with another reader I use. Despite not having any updates for several iOS upgrades, it still works perfectly. Ads are small and unobtrusive. My go-to non-PDF reader app. (Not saying it can't read PDFs, just saying it handles non-PDFs the best of all the reader apps I've used.) There are problems reading nested archives, but that's an easy fix. Thanks, developer!
2 page landscape pdf view!
Finally an app with two page landscape view for viewing PDF's on IOS devices to include iPhone! AND ITS FREE??? It took me ~5 years to find this. It needs to be advertised better by Apple because there are countless other people I've seen on forums who are searching for this functionality. On top of everything you can go left to right or right to left. May God bless you (the developers of this app) and your family/progeny with endless blessings in this life and the next.
With Family Sharing set up, up to six family members can use this app.
