Fun app. However need more of the common patterns(four corners, double bingo without hardway or with four corners, letter X, or even a custom pattern). Also would like to be able to use the board without having numbers called, such that you could use a regular manual hopper and still use the screen to track numbers called. Maybe add a bluetooth function to use a couple iPhones as cards and the iPad as central caller.
