This welcome screen will greet you when you open the Yi Jing Library app for the very first time. By clicking on “Start the App”, you will reach the Question Screen of the app.

The app contains all the functions you have always wanted in order to work with the Yi Jing. The translations and interpretations of various authors are available to you in a precise and detailed form.

In the Question section of the Oracle Screen, you can enter a question. Try to ask a question which has been on your mind for a while and definitely needs an answer. The more specific your question is, the more meaningful will the answer be. Similarly, the broader the question is formulated, the more uncertain will the answer be.

It is important to take your time when you consult the Yi Jing. Furthermore, the usage of physical yarrow stalks or coins expresses your emotional attachment to the question and your intuition better than a random generator. 

For more information, please refer to the instructions on the Q&A page.

You can choose between three different methods of consultation:

  • Using yarrow stalks or coins: Enter the received values by clicking on the “Manual” button.

  • Relying on probability with coins: Click on the “Coin” button six times. This corresponds to the usage of physical coins.

  • Relying on probability with yarrow stalks: Click on the “Stalks” button six times. This corresponds to the usage of physical yarrow stalks.

These consultation methods are explained in the Q&A section of the app.

By clicking on All Hexagrams, you can directly access all the information on a particular hexagram. 

The columns show the upper trigram or the upper half of the hexagram while the rows represent the lower trigram or the lower half of the hexagram. This enables the selection of your hexagram based on its appearance.

The example image shows the process of manually entering the values received from a consultation by using physical yarrow stalks or coins.

On the image, you may find an example of an ongoing consultation process with virtual coins.

As soon as the consultation process is complete, the answer screen will be shown. The answer hexagram will appear on the left side of the screen and the tendency hexagram on the right side of the screen. The tendency hexagram only appears when there is a changing line in the answer hexagram.

These changing lines are yellow and have either the numerical value 6 (broken line, old Yin) or the numerical value 9 (unbroken line, old Yang).

By clicking on the Edit button, you can adjust the date and the location of consultation, the name of the consulter and the question itself.

By using the Share button, an excerpt of the answer to your question can be shared with your friends either via email or a messaging service such as WhatsApp.

You can now navigate to one of the interpretation texts by clicking on the Library button.

Simply by tapping on the downwards arrow will the content of a commentary be unfolded. Similarly, using the upwards arrow will hide it once again. The same showing and hiding functions can be found in each individual section of that work.

On the “Original” screen you can analyze your answer hexagram by viewing the original section of Yi Jing to that specific hexagram.

After opening the Original field and a section of the Yi Jing text, The Judgement here in the example image, a detailed definition and the concordance of every character will be shown in a future version of the Yi Jing Library.

A translation and an interpretation of the Baynes commentary are shown in this example.

You can select two or more works simultaneously in the tab Compare, which simplifies the comparison between different interpretations greatly. After clicking on Compare now, you can see all (the corresponding sections) the chosen works at once (Please refer to the next example image).

By rearranging most of the works into the standardized Wilhelm-Yi Jing structure, a precise and quick comparison between different commentaries is available for the first time.

The chosen works in the last example image are shown here: divided into sections according to the Yi Jing’s text and stacked one upon the other.

On the structure screen you may find various hexagrams derived from your answer hexagram. For more information on the meaning of these derived hexagrams, please refer to the Q&A section.

On the dynamics screen you will find Adrian Stahel’s commentary on the dynamics of the Yi Jing, published for the very first time. He describes how close Yi Jing and Western systems theory are and sheds a completely new light on the Book of Changes.

Under Q&A, numerous questions about Yi Jing are answered in German and English.

In the shop you can convert the basic version of the app to the premium version. Among other things, this allows you to purchase additional commentaries on the Yi Jing from a variety of authors who commented on the Yi Jing from different points of view. This includes the dynamics commentary by Adrian Stahel, which offers a completely new perspective on the Book of Changes by demonstrating the close connection between the Yi Jing and Western systems theory.

On the Old Questions screen, you will find an overview of all previously asked questions, including when and where the questions were asked. The resulting answer and tendency hexagrams for each question will be shown as well. By clicking on the older questions, you can access previously received answers and their interpretations at any time.

You can search the list of old questions by keywords and sort them by alphabet, priority, location and time of the consultation.

In the dialog box Settings, which can be accessed from anywhere in the app via the three-point menu in the upper right-hand corner, you can choose between the following user interface languages: German, English, Mandarin and Russian. Furthermore, the premium version enables the usage of a personal username.

The font and size of the interpretation texts can also be configured to your preferences here. With the premium package you receive 20 different attractive fonts. You can check your chosen font in the preview text field below.

To get a separate backup file of your questions to the oracle, click the three dots on top to the right to open the menu. Then click on ‘Export questions’. It will generate a backup file of your questions to the oracle automatically on your device.

To import a backup file of your questions to the oracle, click the three dots on top to the right to open the menu. Then click on ‘Import questions’. Now, you see a list of your backup files and you can choose the right one according to the time stamp. Afterwards, you will be asked if you wanted to import ‘Only missing’ or ‘All’ the questions in chosen backup file. If you choose ‘All’, then all the questions you currently have in-app will be overwritten with the chosen backup file. If you choose ‘Only missing’, then only missing questions will be imported, which are not displayed in ‘Old questions’.

You need to connect your device to the chosen computer first, before it is possible to start the transfer/copy of your exported questions. Afterwards, start iTunes or Finder. There you can transfer/copy the export file to the hard disk of your chosen computer. If you want to transfer/copy the file to another device, you need to connect the other device to the computer and start iTunes or Finder. On iTunes or Finder you then can transfer/copy your exported questions to the other device.

The exported data are in a csv-data file (compatible with Excel). It is structured as follows: ID, Question, Rating, Date, Location, User name, List of line values

In order to transfer/copy your exported file, you first need to find the file in the ‘Files’ app on your device. Normally, the file is saved in the folder ‘YiJingLibrary’ in the internal storage of your device. If you open the folder, you can choose the wanted file for transfer/copy. A transfer/copy could be done by connecting your device to your computer or by clicking ‘Share’.

After the wanted file is transferred/copied on your computer, you can also transfer/copy the file to your other devices by connecting them to your computer. If you have sent the wanted file by the ‘Share’ function to yourself instead, you need to download it first. After the transfer/copy or download process is complete, open the menu by clicking the three dots on top to the right in Yi Jing Library app, and click on ‘Import question’.

The exported data is a csv-data file (compatible with Excel). It follows this structure: ID, Question, Rating, Date, Location, User name, List of line values
