Pros and cons of KyBook - EPub,FB2,PDF,DjVu Reader app for iPhone and iPad

KyBook - EPub,FB2,PDF,DjVu Reader app good for

It is the best djvu reader that I know. It also reads .epub, .chm, .pdf, .cbz and .cbr, although with limited options for these two last formats of books. Dropbox, Yandex and Google Drive support. Several fonts for .epub files. Useful features like bookmarks, link for the last page viewed, fullscreen mode, text to speech, navigation pages bar, lock rotation, alarm clock and bookshelves. But I miss the features "lock zoom", "lock drag direction" and a "total lock page (include locking previous/next page)". Different modes to organize your library. Edit title, author and others informations of the file. Visual is simple but beautiful.
The version free have support to Google Drive, One and drop box totally free. And have a link with Gutenberg project. Amazing!
This is truly the Swiss army knife of ebook readers. Hats off!
Thanks for a great app! Upgrade to pro is worth it. Please support adding user fonts with IOS internal Open-In-App dialog. I can open fonts with kybook from file manager, but font is not showing.
One of the best. The only problem that it does not PDFs in 2-page mode.
Pros: Elegant, configurable, Cloud Support, good looking, Bad: No German language, only two cloud options for syncing bookmarks, Suggestions: It would be nice to download multiple books at once or folders.

Some bad moments

Its a good app but I cant download books, I would say 2 and a half stars
This app recently introduced full page advertisements that can only be removed with a pro version. They advertised a discounted pro version, so I decided to buy it, then they said I had to leave a review of the app on Facebook. I left the review and they still didnt give me the discount!
Great app, but it also would be great if it be able to synchronize pages, not only books between devices.
A while ago I loaded a book in DJVU. Free version was capable of reading it. That is why I loaded a book into this program. After a while on attempt to read it again I was informed by the app that no way any more - and I must buy pro. AND IT DOES NOT EVEN ALLOW ME TO RELOAD THE BOOK INTO ANOTHER APP. it is clear blackmail. NEVER HAVE A DEAL WITH A BLACKMAILER.
Use this on planes all the time. Love listening to audio clips when I have no service.
This app would be perfect if tags synced across devices. Ill definitely upgrade to pro if/when that functionality becomes available. It would also be better if you could adjust font size, etc, from within the book rather than having to close the book and go back to the settings menu.
