Shakyo: Heart Sutra Copying

Shakyo is the Japanese practice of copying sutras by hand. This app lets you do it on your iPhone: one large character at a time, tracing a faint model with your finger, until the Heart Sutra fills a traditional vertical sheet in your own handwriting. ONE CHARACTER AT A TIME • A big writing box with a faint model character (0–50% opacity, or hidden) • Optional 米 and 田 grid guides • A pen with brush-like thick and thin strokes, in three widths • Back, Rewrite and Undo; leave anytime and pick up at the same character • Optional auto-advance after 1.5 seconds A REAL SHAKYO SHEET • Vertical columns of 17 characters: title, text, your wish, the date and your name • Pick a traditional wish (family safety, good health, passing an exam…) or write your own • Dates written in kanji, Japanese era style • Pinch to zoom; save or share the sheet as a PNG image A QUIET DAILY HABIT • A calendar of the days you wrote and your current streak • Sheets finished and characters written • Every finished sheet kept to look back on • An optional daily reminder at a time you choose PRINT IT, TRACE WITH A REAL BRUSH (PRO) • Export an A4 landscape PDF with faint model characters, print it, and trace with a brush or brush pen • Print or share your finished sheet in A4, too TEXTS Free: the Heart Sutra in its Japanese shakyo form (with readings), plus Simplified and Traditional Chinese versions.
