I think the content is very informative. I have been reviewing it with our teen youth group. I am not fond of the "So What" comments because they seem like an afterthought. And the icons no longer appear on my ebook but that part isn't a huge deal.

I find that this app would be very helpful with lots of great knowledge. The only downfall I see that could be user error is if I click the blue hyperlink to try to view a specific chapter (CB viewer) it doesn't take me there. I have to flip all the way to that chapter, then if I want to go back to the chapter selections, I have to close out & it takes me back to my library. I would've definitely given higher ratings if the android app was more friendly to use. That has nothing I am thinking to do with the book and maybe the app as this is the first book I've purchased to know if it is app or book error. I use Google Books & Kindle on droid without issues but getting this book on those want an option sadly. I would recommend but maybe in another format.
