Disappointed with this app. – Bingo Machine - Bingo Number Caller Review

This app has a lot of glitches on my iPhone. All of a sudden the voice stops working, but the numbers continue on the screen. Also will not stop when I hit pause. We enjoy playing bingo with our disabled son, but this is very frustrating. Please create a fix.
