Installed KOReader and I can confirm that you can read:
- Mathematical Books
- Computer Science Books
- Engineering Books
- Textbooks
of ePub format.
The truth is, that the rendering of the page with KOReader is not as nice with PocketBook, but it is still better than NeoReader V3.0.
The situation is that PocketBook somehow renders the pages in a very professional way, and knows "Tip Boxes" and other tricky css layouts. It even "grayscales" some backgrounds in text boxes.
But as I said PocketBook contrast is just bad.
With KOReader not only can you set a very high contrast, but will keep images separated from text. In other words will keep images normal and text dark.
KOReader will be my default reader. Might not render pages as super professionally as PocketBook, but it is good enough, and contrast is phenomenal, where PocketBook contrast is bad.
And yes I also noted the page turning speed with KOReader. I do have some complaints on how to set things up, but that is just lack of knowledge regarding usage.
Thank you Galunid and salamanderjuice for recommending this.
Tried Adobe Digital Editions and do not like it, it has its own library.
