Super PiBench

7.0: Apple Watch fully upgraded — multi-core computing and global leaderboard submission! See where your iPhone, iPad, Mac and Apple Watch rank worldwide.

Super PiBench computes Pi to any number of decimal places using the Chudnovsky algorithm — one of the fastest known methods. Built on a high-performance C/GMP engine for dramatically fast computation, comprehensive benchmarking, and a global leaderboard to see how your device stacks up worldwide.
