A free app for Android, by GeorgieLabs.

RealPi is a free Android app that allows you to calculate the value of the mathematical constant pi to a high accuracy. The algorithm uses the numerical methods of the real world and not the ones of the mathematics world, which allows you to calculate the value of pi to an accuracy that is not found in the literature.

The app uses a high-quality implementation of the algorithms that calculates the value of pi to a high accuracy. The results are stored in the memory of the device, so you can view the results at any time.

It is possible to choose the number of digits of the output and the accuracy of the results. It is also possible to search for the digits of pi in the result and see if they are in the correct position.
