Good but...

I wish you could edit the book title, author, cover photo and the like... The inconsistency is killing me.

Good, but not as good as it should be.


It's good at basic display of text, but there are major annoyances that bug me if I try to use it to read. First, you cannot turn off that ugly swipe page turn, highly distracting. Second, you cannot change the spacing between paragraphs, which makes it difficult to tell that you have gotten into a new paragraph. Adding the inability to change paragraph first line indentation is merely adding injury to insult. I hope they can improve this, but right now it is not ready for prime time.

Could be great.


The app could be the perfect reading app. A few flaws keep it from being that app.

1) you cannot delete highlights in PDF documents. You can in ePub but not PDF. So if you get the highlight wrong the first try, you are stuck with it. If you try to re highlight the correct text, you end up with double highlighted text.

2) iOS fonts need to be available for ePub files.

3) note icon; when you create a note in an ePub book, the note icon sits right next to the corresponding text. When you create a note in a PDF book, the icon will show up in totally random locations on the page.

1 and 3 make the reader useless for university textbook reading.
