MingJing: BaZi & Zi Wei Chart

Free and offline. One profile, two charts: BaZi and Zi Wei Dou Shu with true solar time, 12 palaces, patterns, 13 readings and compatibility, all on device.

MingJing is a free BaZi and Zi Wei Dou Shu chart app. No account and no ads: your birth profiles and readings stay on your device, and every result shows how it was calculated.

THREE PROMISES • Free for good: no in-app purchases, subscriptions or ads • Local: no sign-up, your birth data never leaves the device, no analytics or tracking • Transparent: time zone, true solar time, solar-term times, school options and engine versions are shown for every chart

BAZI (FOUR PILLARS) • Ten Gods, Hidden Stems, Twelve Growth Stages, Na Yin, Void, Conception Pillar, Life and Body Palace • Ten-year Luck Cycles and yearly pillars, with the start of each cycle to the minute • Birth city search with 418 cities; time zone and longitude filled in for you, or enter them manually • True Solar Time with historical daylight saving handled (including China's 1986–1991 DST) • Solar terms compared by exact instant, so births outside China switch at the same moment as in Beijing • Unknown birth hour?

ZI WEI DOU SHU (PURPLE STAR) • The same profile gives the twelve-palace chart, using the same birth instant, true solar time and late Zi rule as BaZi • Classic square board: major, auspicious, malefic and minor stars, seven brightness levels, birth-year transformations • Natal, Decade, Year and Month layers stacked on one board, with a year slider and the flowing stars of each layer • Long-press any palace to read it as the Life palace, for example the Spouse palace to look at a partner • Palace details: the four directions, flanking palaces, borrowed stars for empty palaces, the twelve spirits • Pattern cards with required, bonus and breaking conditions and the classical source • 13 readings: overview, personality, relationships, career, money, health and more, each line with its source; export all 13 as one PDF • Ask your chart: questions answered by the on-device Apple Intelligence model, each point citing the palaces, stars and patterns it rests on (shown only on devices that support Apple Intelligence) • Compatibility: spouse palaces, transformations into each other's chart, branch relations and 30 years of decades in step. Structure only, no score • Four school options (brightness table, leap month, late Zi hour, new year); everything else uses the mainstream defaults listed on the Basis page

BAZI × ZI WEI Solar-term pillars next to lunar pillars with every difference explained, luck cycles and decades on one timeline, the Day Master next to the Life and Body lords, and the element balance next to the five-element class.
