What Daoly is

Daoly is an iPhone app for BaZi (Four Pillars), the I Ching, and the Five Elements, made by ldjing studio. It is available in English, German, Spanish, French, Japanese, Korean, and Simplified and Traditional Chinese.

How we approach these traditions

  • Reflection, not prediction. We present BaZi and the I Ching as cultural traditions and tools for thinking, not as forecasts.
  • Show the working. Our calculation rules are published with test cases so anyone can check them.
  • Calculation is separate from interpretation. Charts come from deterministic calendar algorithms. AI is used in the app to write readings from a chart that has already been calculated.
  • Birth details deserve care. See the privacy policy for what is stored and where.

About the content

The guides are written and maintained by the Daoly team. Classical I Ching passages come from the traditional Chinese text; translations and plain-language readings are Daoly's own. Interpretations reflect common traditional framings, and schools differ.
