Which one do you prefer, read manga by an app or by a book?
I prefer manga reader app and Zingbox is my favorite.
So what about you? app or book?
I've edited your post and erased the link to the manga app, because free commercial advertisements are not allowed on this forum. Contact the admins (the users in red) for permission.
Just to be on topic, I for one if I had the money I would prefer reading manga from a book, because not only it makes it easier on the eyes, but you can also admire the art of the mangaka on a higher level. Anyway, until that time comes I'm satisfied with reading them online.
