PiSeeker

PiSeeker is a fun and challenging app for anyone who loves memorising the digits of pi.

Three ways to play:

🎙️ Recite — Speak the digits of pi aloud. PiSeeker listens in real time, shows you the digits as you say them, and counts how many you get right before you make a mistake. Start from any point in pi — just say the first 7 digits to set your position.

⌨️ Type — Tap digits on a number pad as fast as you can. A running count shows how many consecutive correct digits you've entered.

🔍 Seek — You're shown a position number and must enter the correct digit of pi at that position. Set your own range to focus on the digits you're learning.

Features:

Speech recognition runs entirely on-device — no internet required for Recite mode
Personal bests and scores tracked across all three modes
Scoring system rewards longer runs
Sound effects for correct and incorrect answers
Works offline
Whether you're a pi enthusiast, a student, or just up for a memory challenge, PiSeeker makes it easy to practise and improve.
