π314: Master of Pi

Dive into the world of Pi with a single tap. π314 is a simple, beautiful app for viewing, memorizing, and challenging yourself with the digits of Pi. ■ 1,000,000-Digit Viewer Smoothly scroll through one million digits of Pi after the decimal point. Type in your birthday or any favorite number and instantly find where that sequence first appears in Pi. Discover fun facts like "my birthday shows up at digit 12,345!" ■ Memory Challenge How many digits can you recall? Test yourself on the keypad. Three misses ends the run, and you get one hint. Clear them all for a "PERFECT," and beat your personal best to set a new record. ■ Records & History Your challenge results and best score are saved automatically. Hint and no-hint runs are tracked separately, so you can watch your progress at a glance. ■ Crafted Design & Sound An immersive dark theme with glowing neon aesthetics. Choose from five tap sounds — Click, Pop, Beep, Marimba, or Drop — or turn them off entirely. ■ English & Japanese Switch languages anytime inside the app. ■ Privacy First All records and settings stay on your device. No account, no personal data collection, no internet connection required. Play offline, anytime. Whether you love math, want to sharpen your memory, or aim to break your own Pi-recitation record, π314 lets you savor the infinite digits of Pi.
