Very nice! Love the big numbers on the external screen!

Update: Very responsive developer! Crash issue was fixed within days. The one issue I really hoped would be addressed, accidentally dropping multiple balls in succession, was also fixed. Thank you very much! Perfect once again!

Update: Latest version crashes trying to go to settings.

Im using this for bingo at a retirement home. It would be helpful if the balls fell straight down so they are easier to read. The extra real estate could be used to enlarge the called numbers. Also, label the blocks of balls, B, I, N, G, O so its easy to see when all numbers are called for a letter. Also, if you could prevent multiple clicks, where balls just keep falling, that would be great. Ive been looking for a bingo app that the elderly can handle, and youre very close. Keep up the good work!!! Nice job!!!
