You can manually tap a button to pick a random bingo ball or you can set it to automatically call bingo balls on a scheduled interval. Bingo Caller has a feature to display to an external display or screen. All you have to do is turn on the Air Play / Apple Screen Mirroring feature and Bingo Caller will display the called numbers to that screen. Bingo caller also features the ability to chose from a Male, or Female voice for calling the bingo numbers. You can also optionally, disable the voice if you do not wish to use it. Bingo Caller also displays the current BINGO pattern that needs to be completed in order to win. It has a variety of preset patterns that can be used.
