## What is The I Ching or Book of Changes?

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.

### 5/5 — WHAT HAPPENED?

*2025-09-05*

My original review is below.  But suddenly the sync stopped working, the developer page for support gives error message, the email to the support comes back as undeliverable…. Is this all from the new update last week?  

Gorgeous design, rich library, best translations (including the complete Wilhelm), study and divination woven into one, gorgeous interface, space for journal, comments, notes, syncs over Cloud, I have used it for years and give it ten times ten stars. Thank you to the developers.

### 4/5 — go

### 5/5 — A great digital adaptation

*2024-12-20*

This is the best Wilhelm-based I Ching online that I have found.

### 5/5 — Insight

*2024-11-01*

This easy to use app is very authentic and very useful to both study the I Ching and to consult the venerable oracle.

### 5/5 — Wonderful app

*2024-09-04*

I absolutely love this app and would recommend to anyone.

### 5/5 — Brilliant app, ten times ten stars

*2024-08-26, version 2.4*

Gorgeous design, rich library, best translations (including the complete Wilhelm), study and divination woven into one, gorgeous interface, space for journal, comments, notes, syncs over Cloud, I have used it for years and give it ten times ten stars. Thank you to the developers.

### 5/5 — Can’t imagine a better I Ching app.

*2024-08-06*

I can’t say I’ve tried a ton of I Ching apps but I can’t imagine any other being better than this one. If I may be permitted one critique it would be that the bottom bit of text for the readings is cut off and I need to swipe up and hold to see all the text. This is on an iPhone 8 so not sure if it’s just my phone or not. Other than that it is pure oracular perfection.

### 1/5 — Can’t figure out how to manually input

*2024-04-06*

I thought I’d be able to manually input a hexagram so I could do it in person and journal on the app, but from what I’m seeing I can only cast a hexagram using the app

### 5/5 — Wilhelm’s translation

*2024-01-22*

This app has become for me a daily reading requirement.  Since I found this app I have been reading the text more infrequently and have learned so much more from Wilhelm’s writings than any other translation available.  The app allows a deeper understanding of the trigrams and is a real treasure to own.  The ease of use and clarity is so important to me and has made the study a daily joyful experience.

### 5/5 — Love the original text and multi- method throws

*2022-11-14*

Only thing I’d want is easier text formatting. I love the way it serves as a journal, and you can even export.
