Calculate Pi Legacy Edition for older devices (OS versions 4.3-6.1)

Calculate Pi now on your iPhone or iPad!

The advent of digital computers in the 20th century led to an increased rate of new π calculation records. John von Neumann et al. used ENIAC to compute 2037 digits of π in 1949, a calculation that took 70 hours. Additional thousands of decimal places were obtained in the following decades

Now YOU can calculate thousands of decimal places of Pi on your own iPhone for free! What an extremely geeky pleasure!

----------------------------------------------
Not everyone can afford a new phone every two years. Therefore, this is the legacy support version of Calculate Pi that runs on all devices with iOS versions 4.3-6.1. Enjoy!
