Yarrow — I-Ching Oracle

Yarrow is a quiet I-Ching companion for your iPhone.

Ask a real question. Cast a hexagram by the present moment, or by three numbers. Read the answer.

What sets Yarrow apart is the sources. Most I-Ching apps paraphrase. Yarrow draws from nineteen classical Chinese commentaries — Yang Tian Cai, the Duan Yi Tian Ji, baihua notes, Zhu Xi's Book of Changes — translated into clear English. You see the modern reading, the historical anecdote, and the original Chinese on tap.

– Two casting methods: time-based, or three-number input – 64 hexagrams, 384 lines, with moving lines (bian gua) computed for you – Classical sources in English: Overview, Judgment, Commentary, Plain-language note, Historical anecdote – AI reading: your question + the cast + the classical sources, woven into one calm reply – Journal: save readings, look back at how the lines unfolded – No account. No tracking. 30 readings a day; the oracle rests at night.

This app is for reflection and entertainment. It is not a substitute for professional advice in finance, medicine, law, or relationships. The I-Ching is a mirror — what you do with the reflection is yours.
