Very low sound

Just like the other reviewers, I was very disappointed to discover how low of a sound this has. You have to crank it up to the max volume to hear something. It’s such a shame. I feel I wasted money on this. Such easy fix too. Why can’t this be fixed?

Sound needs to be fixed

The concept is great but the sound doesn’t work. I wanted something to teach my 2nd grader some ELA concepts but unfortunately this will not hold her attention without sound.

No sound

It seems like a good app. It would be better if the sound worked. I have a new IPAD Air 2 and this app has no sound on it.
