Don't trust fake (I mean: F.A.K.E) PI calculating applications. It's IMPOSSIBLE to calculate million digits of PI in one second on a mobile phone! This application is the real deal. Your phone will get warm and probably even hot while performing millions of computations. This is how it should be in the real world.
To prove this is not fake, try this: Calcultate PI to 1.000.000 digits on your phone. Upload your benchmark. There is a button to save all calcultated digits to a file (I could not squeeze 1.000.000 digits into the application of barely 150KB). Those digits could be easily compared with precalculated values of PI found elsewhere on the internet.
