This app works really well with iPad Pro

I own a lot of ebooks with a fundamental problem: some books just don’t view well on my small iPhone screen. These include: art books, comic books and graphic novels, photography books, books on crafts such as sewing and cooking and needlework, etc. For books with heavy graphic content or lots of pictures, I put them on my iPad Pro with 12” screen, and I use this app to view my books. It displays the pictures in glorious color. If you have problems with your eReader cutting your pictures in half on two pages, I recommend this app.

Annoying popup to purchase and an even more annoying menu system

After having the app on my iPad Pro 10.5 for a few weeks, the app started showing a popup every time I opened the app from fully being closed. The popup forces you to click one of two options: buy now or buy later. It continues to ask each time I open the app now.

Before the above annoyance, upon fully testing the app, I quickly realized that the menu system is in need of a serious redesign. There are too many different paths to take in order to arrive at the same action. Some features are hidden and would take most users a while to find them. Some features only work within some views yet this won’t be clear to a user until he has tried everything as I have. Imagine having a jpeg picture file on your windows PC. Right click on that picture, no matter what folder you put it in, will always bring up the same menu for that picture file. The same can’t be said about tapping on the same book cover in different views/folders in this app.

Awesome App For Reading EBOOKS!!

I started using the KyBook App a few months ago. Before I discovered it, I used Kindle and the Apple iBooks app for most of my reading. Well, no more. I absolutely love KY Book and use it exclusively because it's so much better than all the other EBOOK readers out there. You can totally customize your ebooks by creating colorful themes, choosing your favorite font (There are about 50 you can choose from!) and adjusting the spacing etc. I am so happy with this app, I just can't tell you how awesome it is. Thank you to the KyBook app creators for making a totally customizable EBOOK Reader!!
