Pi — Infinite Digits
Every digit of π, instantly.
Free · Designed for iPad. Not verified for macOS.
Discover π like never before.
Pi — Infinite Digits lets you calculate any decimal of the mathematical constant π with absolute precision. Whether you're a student, a mathematician, or simply curious, this app gives you access to the infinite digits of π directly on your iPhone.
Two powerful modes:
First N digits — Display the first N decimal digits of π, from 1 to 50,000 locally, and beyond via the internet.
Nth digit — Find exactly which digit appears at any position in π. What is the 1,000,000th decimal? Find out in milliseconds.
Unmatched precision:
Pi uses the Chudnovsky algorithm, one of the fastest known methods for computing π, combined with arbitrary-precision arithmetic (BigInt). Every digit is mathematically exact — no floating point approximation, ever.
For large numbers:
Beyond 50,000 digits, Pi seamlessly connects to Google's pi.delivery API, giving you access to over 100 trillion decimal digits of π. The largest calculation ever made, right in your pocket.
Features:
Arbitrary precision up to 50,000 digits — fully offline
Unlimited digits via internet (Google pi.delivery)
Real-time progress bar with elapsed time
Calculation history (last 5 results)
Copy result to clipboard
Export and share your results
Clean, intuitive interface
No ads, no subscriptions, no data collection
Did you know?
π (pi) is an irrational number — its decimals never repeat and never end. Mathematicians have computed over 100 trillion digits. Now you can explore them too.
