FlipHTML5

So when I first downloaded this app it worked perfectly fine then I downloaded it again and it did not load on any book.

When starting, it briefly shows its logo, then the screen goes dark and nothing more happens. Unusable.

This app works and does allow you to find, read and download hosted publications. However quirks in the app ruin the usefulness of the app and make it frustrating to use. For example, zooming in often makes the viewed page jump unpredictably around and the user ends up viewing a part of the page not intended. Another example, after clicking on a link and having to view the linked webpage in Safari; when the user returns to FlipHTML, the publication will regularly flip back one page, forcing the user to flip forward one page to return where they original were in the book before clicking a link.
