Pidactic was created to help you memorize pi and to demonstrate to my son we could build an app! There are two distinct areas within Pidactic, both contain 3,141 digits of pi. The Digits area allows you to sift through digits of pi by groups of five, three, or one to help you memorize. The Test area gives you an opportunity to show off. As part of a test, the app will calculate how many correct digits youve entered, how many digits in error youve attempted, and even provides a hint (correct digit) button should you get stuck. However, using the hint button will cost you one point. Additionally, as part of the Test, you can reach various mathematician levels based on your total score. See how far you can go. Good luck, and have fun!
