About this app

“Simply the best.”

Unlock the wisdom of the ancient Chinese oracle with this beloved app crafted for both curious beginners and deep-diving devotees. Ask a question, get a thought-provoking answer — no gimmicks, no fake bamboo wallpaper — just the 2000-year-old original text and a fresh, poetic, modern interpretation.

This free trial version gives you ten free consultations OR ten days to try it out, explore the features, and decide if it's right for you.

Built on an open-source engine that replicates the ancient yarrow stalk method with mathematical precision, this app honors tradition while embracing clarity, accessibility, and the pure love of what Carl Jung called "meaningful coincidence" and what mystics have described as "the voice of the universe whispering through patterns."

✨ Why users love it:

Because it’s more than just a divination app. The commentaries draw from a rich tapestry of influence — Lao Tzu, Doctor Who, the Grateful Dead, T.S. Eliot, Dylan, Pynchon, Tarot, MLK, Emily Dickinson — all woven into readings that feel startlingly relevant and emotionally resonant.

This isn’t just software. It’s a modern conversation with the ancient Tao.

⸻

No phony parchment. No cartoon sages. No lottery numbers.
Just a powerful tool for reflection — refined since 1989, when I first released it via CompuServe and floppy disk.

Ratings and reviews

incredible app - so insanely well done, thank you so much for making this! seems to not be working on s23+ after latest OS update, heads up

A hidden gem, this app's simplicity modestly disguises its utility and ease of use. The developer has added a journal as so you can track your progress in navigating Change with a sound translation and the lyrical and thoughtful commentaries. You can also compare and contrast different translations by using the Library tab to quickly look up Trigrams, hexagrams, and whole readings you may have done with other texts by entering the hexagram cast and its moving lines from 1 to 6. It's excellent.

#a11y-hit! #talkback-compatible. This app can throw coins for you or you can throw your own coins then enter your results. It's one of a few accessible iching apps in the play store. My thought on divination for anyone with a sensory deficit is we have a perfect right to use any divination that works for us to level the playing field to whatever extent possible.

What’s new

Maintenance release fixing edge case bugs: nav bar overlaps on flip/foldable phones. Version 18 introduces notifications -- bite-sized nuggets of wisdom from the book that you can set to greet you at a specific time, or to surprise you at random daylight hours.
