Yarrow Stalks Method
This method (which is, by its own meditative nature, rather slow and laborious) has been faithfully implemented into Deepware Changes respecting its essence.
In order to use it simply split into two stacks the stalks scattered through the screen touching (or dragging) within the circle with your finger. Obtaining of a single digit needs 3 touches, demanding a total of 18 touches for each query.
The counting of the yarrows and the calculations are totally automatic.
