Excellent Galton Board App
This app is fun to use because you can vary the number of rows and the number of beads. I especially like seeing the exact number of beads in each bin so I can look at the statistical variation from cycle to cycle. I would like to see a repeat button added so I would not have to reenter the number of beads every time. Having a 1000 bead button would also be convenient for running a many bead simulation. The app seems to produce the Pascal’s triangle bead bin probabilities very well. The random number generator appears to have a random offset so each run of the app produces different results. Would you comment on the random number generator you use? Great app! Thank you!

Please fix the math! It’s misprogrammed but love the idea!
I want to give this app five stars, but after 20 trials, it’s incredibly clear that it has been misprogrammed. for example, you will always see a higher number than expected of balls on the outside, which should average out to 1/8, 1/16, 1/32, 1/64 depending on how many rows.

Hi Dan, thank you for bringing this to my attention. I was able to reproduce the issue, and it has been resolved in the latest release. - Edwin
Very nice
Good representation of the theory.
Love this app!!
This app is so simple and easy to use. It’s fun. My only suggestion is if stationary at the bottom of each of the columns if there would also be a percentage (00.00%) of the total.
Tedious gimmick
Why in the world wasn't this app written so we can EASILY enter ANY NUMBER?
Response from developer
Hi tabaks, thanks for your feedback. In the next release, you can tap the top number to manually enter any amount.
