App is ok...

...If all you are looking for is a list of books you have “saved”. There is no way to read the book details, mark them as read, or even downloaded. Would be even better if you could read directly in the app. At least need a bit mor functionality. And if these functions are available, instructions how to access!

Developer Response ,
