This app provides different ways of fortune telling such as Bát Tự Hà Lạc or Quẻ Lưu Niên Thái Ất.

The app also includes a reference to the Hà Lạc chart, which appears when the user selects a year for fortune telling. Users can choose to view different types of charts, including both Dịch and Hà Lạc charts. The app provides detailed descriptions of each chart, including illustrations, nạp giáp, thoán từ, and hào từ. Users can also save, edit, and delete their fortune-telling data. After inputting data, users can read thoán từ and hào từ. The app also includes a basic guide to the 64 hexagrams for reference. Overall, Kinh Dịch is a useful app for those interested in personal fortune telling or learning more about the ancient text of Kinh Dịch.
