In the I-Ching Reference entry in the Divination section, you can tap each of the six bars to create different hexagrams and then read the interpretation at the bottom of the screen.
But did you know that you can tap the instructions in order to get a completely random hexagram result?
That's right - tap the instructions as indicated, and the app will 'roll' a random hexagram for you.
Take it with a grain of salt if you will, but if you don't have three coins handy, or 40 yarrow stalks, or just want a quick and simple result, you can give it a shot.
Open the Wicca Plus app and navigate to Divination -> I-Ching Reference. Then close your eyes, focus on your question, and concentrate. When you feel you've put enough energy into the question, open your eyes and tap the instructions, and see what result you get.
