Ba Zi Fortune is a free Android app developed by Walter Choy that allows users to explore the potential and mysteries of their lives using their birth data. The app is based on the Chinese five-element theory and the Ba Zi (Eight Characters) or Four Pillars, which is a sophisticated art of Chinese fortune-telling. With Ba Zi Fortune, users can investigate the cyclical influence of their destiny in important areas such as family, friends, relationships, wealth, fame, recognition, career, studies, partnership, business, and almost every other important aspect of their lives.

The app's main feature is its BaZi calculation, which enables users to evaluate relationships and forecast the life path of each individual. The app is easy to use and provides a detailed analysis of the user's BaZi chart. The app is ideal for those interested in Chinese astrology and fortune-telling, as well as those looking for insights into their life path and potential.
