Ancient oracle meets modern classic! Explore an interactive English version of "The I Ching or Book of Changes" by Richard Wilhelm, edited by Hellmut Wilhelm, and translated by Cary F. Baynes, using a coin oracle or yarrow stalks, and an integrated journal.

NOTE: The text is only in English.

The I Ching, or Book of Changes, a common source for both Confucianist and Taoist philosophy, is one of the first efforts of the human mind to place itself within the universe. It has exerted a living influence in China for 3,000 years, and interest in it has been rapidly spreading in the West.

“Princeton's Bollingen edition—still regarded as the best and most authentic by I Ching aficionados.”

The complete work is available in three books. Book I is included with the I Ching or Book of Changes app. Book I includes Judgments pertaining to the diagrams as a whole, the line texts, and the Great Images.

Book II and III are available for additional in-app purchase.

Book II: The Material
Contains the Shuo Koa and the Ta Chuan from the Ten Wings, plus The Structure of the Hexagrams.

Book III: The Commentaries
Contains passages from the Ten Wings considered commentary to the texts, and On Consulting the Oracle.

They did it right ! The original.

Well I was waiting for this, the original translation of R. Wilhelm.
I have carried this book around the world for 25 years for the infinite wisdom it provides to who wants to listen. It is a classic. I do still like to throw the coins myself but what is important is that this is the real thing, the real book. The I Ching book of mutations is a strange world and at the same time familiar. Self knowledge is the ultimate goal here, the work has to do with a careful search for our character, attitudes and motivations in life. A mysterious spiritual book with enough Mystery that can make you wonder why one loves this book so much, it is like life: a miracle. It is an action book that never gets old and to have it in the iPad is a beautiful thing when one knows it is a cultural treasure. Get this study it you will be studying yourself and the workings of the soul of the world and your own.
Thank you for the quality of keeping to the original translation version from Chinese to German by Richard Wilhelm.
Before this iPad version my printed 25 year old book would stay home being too heavy to carry in my travels, now I will go with this magnificent source work everywhere. In my opinion this work the is inexhaustible.

I use this everyday.


This is a really great app. It is a way to cast the Yi Ching, with some other great features. But it also includes a translation of the Yi Ching that is very good. Wilhelm's translation is my favorite. Reading the book feels like sitting with a wise old granddad that instructs you in what to be careful of as you navigate the world. It is exactly the type of wisdom our modern culture has eliminated from our character. The text alone is worth the price of the app. But that it includes statistically accurate casting makes it a really great value. It is easy to use. Really, get this app. Great product.

A brilliant app


I have carried around the Wilhelm translation of the I Ching for 30 years but no longer. This is the 'must have' app for serious students of the I Ching who wish to experience the profound wisdom this book has to offer. It does everything I need, question the oracle, lay out the hexagram for the present, lay out the changing lines and resultant hexagram for the future. It also has a journal function and an option to buy Book II and Book III. I cannot recommend this app too highly, an excellent app.
