PiCalculator! vs Super PiBench

Do you love Pi, the most famous irrational number in mathematics? Do you want to challenge your smartphone and see how many digits of Pi it can compute? Do you want to learn more about the history and applications of Pi? If you answered yes to any of these questions, then PiCalculator is the app for you! PiCalculator is a fun and educational app that lets you calculate Pi with your smartphone. You can choose how many digits of Pi you want to compute, and watch as your smartphone works hard to find them. You can also see the progress and speed of the calculation, and compare it with other devices. You can also share your results and achievements with your friends on social media.
