Pi By Karina is an app which simplifies the learning process in memorizing the digits of Pi. The app is inspired by a technique that my daughter and I utilized in order to assist her for her Pi Contest at school on March 14th (Pi 3.14 = 3/14 = March 14). Other apps available do not break up the digits into simple smaller groups of numbers. Pi By Karina does this! You can learn many more digits of pi by breaking down the group of numbers as you would in learning a new phone number. Add a little tune to it, and you are set! Good luck! See you on Pi Day! Pi By Karina will go to 10,000 digits of Pi! Also when in testing mode, a scoreboard of the elapsed time will appear so you can see and track how many digits of Pi you can type in a certain amount of time!
