Zi Wei by INNOFUN calculates charts from classical rules and uses AI to explain the relevant palaces and stars, with explicit historical-time-zone, daylight-saving and true-solar-time corrections.
Switch between natal, decade and annual charts with transformation overlays and tappable palace details. Pattern summaries list conditions, with adjustable leap-month, late-Zi-hour and star-brightness conventions.
The overview is free for each person, with two additional readings and three questions included initially; viewed readings remain available.
