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 far you can get with a little practice.
There are a few user settings in the application preferences that you may find useful. The digits are broken into groups of ten by default. You can turn off the keypad sounds. You can reset on start, or retain the last digits.
The option to save the score will only appear if you start from the beginning after choosing Reset, and do not make any mistakes 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.
App will determine which iPhone OS version you are using at start up, and setup the scroll to work properly with each OS. If you have PiBrain3 please remove and use this app instead. See here for more technical details on the differences.
