Über diese App

The Kaprekar App brings math to life with rhythm, story, and interactive exploration.
Dive into the world of D.R. Kaprekar, the Indian mathematician who discovered the mysterious constant 6174 — a number that emerges from a simple digit-flipping algorithm and converges in just a few steps.

🎵 Features:
- A unique background rap that explains Kaprekar’s algorithm in a hard hitting, dirty-south style.
- Interactive demonstrations: enter digits, flip max/min, subtract, and watch the constant appear.
- Background story: learn about Kaprekar’s life, his discoveries, and his
contributions to recreational mathematics.
- Links to further resources, including the Kaprekar Wikipedia page and
MerWare’s lyric showcase.

📚 What you’ll learn:
- How the Kaprekar routine works with four-digit numbers.
- Why 6174 is called Kaprekar’s constant.
- Connections to magic squares, Harshad numbers, and self numbers.

🎮 Why it’s fun:
- Math explained through music and rhythm.
- A playful way to explore algorithms without needing advanced math.
- Entertainment with an educational twist — perfect for curious minds,
students, or anyone who loves puzzles.

Kaprekar is primarily an entertainment app with educational flavor.
It does not collect personal data, does not use analytics, and runs entirely locally on your device.

Discover the hustle of digits, the rhythm of subtraction, and the magic of
Kaprekar’s constant — all in one app.
