Pi Brain

By Henry Chan

This app is only available on the App Store for iOS devices.


How many digits of pi can you remember? Since pi is an irrational number, the digits never end or repeat. You will probably never have to use more than a dozen digits in any calculation, so why learn the digits of pi? For some people this is a challenge. The Guinness record for remembered digits is 67,890 digits.

With this program you will have the opportunity to test your memory, and learn a universal number. Have contests with your friends and family. This is a great learning tool for all ages. You be surprised how much you can remember with a little practice.

The option to save the score will only appear if you do not make more than one mistake and do not use the hint or switch to the learn mode. Scores can be sorted by date, name, or score. Use this list to verify your retention over long periods.

Great game, just one problem

This game is fun, and it helps me alot with memerizing pi, but when I open my scores, it shows nothing. Am I doing something wrong, or is it the game? Other than that it is fun and i love the set up of the game.

Good App

Overall I think this is a good app. One recommendation would be to allow which digit to start or don't count the whole number 3 in the row divisions. Just a suggestion. Keep up the good work!!

Simple and fun

My son and I like playing this game as we learn more digits of pi. I'm up to 230, and he's up to 60. Of course, since he's only three years old, I think he still has me beat.
