## What is Hanhoek?

The Heart Sutra is free to copy from beginning to end.

Hanhoek is a sutra-copying (寫經) app. Trace each character over a faint guide with your finger or Apple Pencil; every character you write is saved on the device, and 다음 글자 moves on to the next.

CLASSICAL CHINESE WITH THE KOREAN READING
Each phrase pairs the classical Chinese text with its Korean reading, character by character. Copy either the original or the reading.

A FEW CHARACTERS A DAY
Set a daily goal; the home screen shows what is left today and how far the copy has come. Going back shows what you wrote.

DEDICATION AND YOUR COPY
After the last character, write a dedication. The days and the dedication are kept, and the characters you wrote become a PDF of your own copy.

PAPER PRACTICE SHEETS
Make A4 sheets with the text in faint ink to copy with a pen.

TEXTS
- Free: the Heart Sutra (260 characters) and short verses
- Lifetime unlock (one-time purchase, not a subscription): the Thousand Hands Sutra (Korean chanting edition), Beopseongge and the four-line verses of the Diamond Sutra, and texts added later

ON YOUR DEVICE ONLY
Your writing and records stay on the device. No account, server, ads or tracking.

Good to know
- The texts are the classical Chinese originals (public domain) with their Korean chanting readings; no modern translations are included. The interface is in Korean.
- The great compassion dharani and some mantras whose Chinese characters could not be confirmed are copied in Korean.
