It's a great app. Make a book of photographs, videos and texts. Unfortunately, you can not save the book that you made in your own files. For example, the photo roll. So you can not do anything with the book you have created. Would the creator of this app to do something about!
You are required to log in with your twitter account. The only way to share it. You can not mail the book.
I give the app five stars for the design!
The app can only be used when the book made can be saved in your file.
I hope that the creator of this app will make this possible.
Thank you!
