Three thousand years of yarrow-stalk wisdom, reading hexagrams through the original I Ching text — full judgments and line texts, read-aloud, and Apple Watch support.
The I Ching (Book of Changes) is one of the oldest classics of Chinese culture, holding profound philosophy and wisdom for life. This app casts your hexagram with the traditional yarrow-stalk method — the oldest and most orthodox way to divine fortune.
[Features]
• Yarrow-stalk & number divination: simulates the traditional yarrow-stalk cast, plus a quick number-based method; derives the primary and resulting hexagrams, marks the changing lines, reads them by Zhu Xi's rules, and offers ritual (筮儀) guidance
• Original I Ching text: the full Judgment, Tuàn commentary, Image, and the six line texts, each line paired with its own Image commentary
• Line-text glosses: phrase-by-phrase annotations that explain how each line's imagery arises (取象), with tap-to-look-up definitions
• Classics & Ten Wings: the Xù Guà, Shuō Guà, Zá Guà, and Xì Cí commentaries, with full-text search and quotation highlighting
• Glossary: every character gloss gathered into one searchable index
• Read aloud: speak the full hexagram text — judgment, line texts, and Image — to savour the rhythm of the classical Chinese
• 64 hexagrams: browse all sixty-four and look up any original text, with pure and monthly-sovereign (消息卦) hexagrams marked
• Sequence Song: the King Wen sequence mnemonic, with tappable hexagram names that open the hexagram detail
• Opposite, reverse & nuclear hexagrams: automatically derives the opposite (錯), reverse (綜), and nuclear (互) hexagrams, with one-tap navigation to broaden your reading
• Ask AI: long-press a reading to ask ChatGPT, Claude, Gemini, or Grok about it with the full hexagram context
• Daily Hexagram: a home-screen and watch-face widget shows the day's monthly-sovereign hexagram and the current solar term
• Reading history: records the date, time, and location of each divination, synced across your devices via iCloud
• Apple Watch: full Apple Watch support — cast a hexagram anytime, anywhere
Divination results are for reference only; their value lies in inspiring thought and broadening perspective.
