This is a simple bingo caller app for Android, created in App Inventor.

It works as it is, but there’s things about it that could be improved. Feel free to have a go, or just use bits for your own projects.

The options in the app:

  • Speed range (1 to 20 second delay between numbers)
  • Number range (1-70, 1-75, 1-90)
  • Sound (on/off)
  • Start/Stop calling numbers
  • Reset

Things the app would benefit from:

  • Sort the called numbers into ascending order
  • Option to read out the called numbers
  • Speed slider to move in 0.5 second increments
  • Keep screen awake while running

What is Bingo?

Bingo, in case anyone doesn’t know, is a game where numbers are picked at random and called out. Players have cards with a selection of the numbers on, which they cross off as that number is called out. The first person to cross out each corner; a horizontal line; or every number on their card and to shout “bingo!” wins.

How to use the app:

  1. Install and run the app
  2. Choose the speed you want (3 to 5 seconds seems favourite with my kids)
  3. Choose the number range (based on the cards you are using)
  4. Press “Start”
  5. Press “Stop” when someone calls bingo
