Do NOT use this app! This was the only way to play the accompaniment tracks for our musical, but the app was awful! The sound was way too quiet for my students to hear on stage. We tried everything we could - making sure volume was all the way up, using different aux cords, adjusting the gain on the mixer board - nothing helped! And the company (Right on Cue) simply said, "we've never had this complaint before so we don't know what to tell you". They wouldn't do anything to help solve the problem. But the volume wasn't even the biggest issue - the majority of the time, a song would just stop playing right in the middle of it or the app would completely shut down! This happened on more than one device as well. Again, I talked to the company and they just said try to delete the app and reinstall it. I paid hundreds of dollars for the rights to play the songs on this app, yet it wouldn't even work! Please let others know so this doesn't happen to you and so your kids aren't left in the middle of a show with no music! Very disappointing...
