Doesn't work – Pearson BouncePages Review

It is useless because my grade seven language arts teacher said that we just have to go to the app and scan it and then listen to it but I can't even get a sound. PS if your teacher says to get this app please read this review and then tell him or her that it doesn't work because there isn't any sound.
