Super PI is an Android application that calculates Pi to a specified number of digits after the decimal point. The app is designed to test the performance and stability of your Android device by using a fast and reliable algorithm that calculates Pi using FFT and AGM. It is optimized for most ABI, including armeabi, armeabi-v7a, mips, and x86.

Super PI supports pre-defined typical digits up to 4 million, allowing you to test your device's performance and stability with various levels of complexity. The app also allows you to easily share your results with friends with a single click.

I tested the app on my Galaxy Nexus, and the results were impressive. The app quickly provided accurate results for calculations up to 4 million digits, with the fastest calculation taking onlyseconds for 8K digits. The app also provides information about your device's CPU, including the device model, CPU type, CPU frequency, and the number of processors.

Overall, Super PI is an excellent app for those who want to test their Android device's performance and stability. It is easy to use, reliable, and provides accurate results for Pi calculations up to 4 million digits.
