PiClimb: Learn Pi Digits

How far can you climb?

PiClimb turns learning the digits of π into a calm, steady climb – and a fast, fun game when you want a challenge.

LEARN • See a chunk of digits, start typing and it disappears – then type it from memory. • Every third chunk you review the whole stretch without help. • Choose chunks of 2, 3, 4, 5, 6 or 10 digits.

PRACTICE • Adaptive practice finds your weak spots and trains them in context. • Continue where you are, choose a custom range or practice a random stretch you already know. • Mistakes show instantly, and you type the right digit before moving on.

RECALL • A pure memory test from the first decimal. The first mistake ends the run. • See exactly where it went wrong and practice that area with one tap.

PI PANIC • Type π as fast as you can before the time bar runs out. • New Game Center leaderboards every day and every week.

TRACK YOUR CLIMB • Personal bests, streaks, a daily goal and a confidence map for every 10 digits. • 20 achievements, from your first chunk to the Feynman Point at digit 762.

APPLE WATCH • Quick Recall, Panic Mini and your progress on your wrist.
