Find your favorable day.

An auspicious date (吉日) is a day whose energy — as read through Chinese astrology — favors a specific undertaking, like a wedding, a house move, signing a contract, or opening a business. Traditional Chinese almanacs (黄历/通勝) have guided this kind of timing for centuries. Auspio automates that reading using Ba Zi, the 12 Day Officers, zodiac compatibility, and Wu Xing, so you can find favorable dates for your own life events in seconds instead of consulting a printed almanac by hand.

Ba Zi, or the Four Pillars of Destiny, describes a person using eight characters — a Heavenly Stem and Earthly Branch for the year, month, day, and hour of birth. Auspio computes your Ba Zi chart from your birth date, time, and location, then uses it to rank candidate dates by compatibility with your personal chart and to generate your daily luck reading (today's score, lucky hours, colors, and direction).

Zi Wei Dou Shu — the 'Purple Star Astrology' — is a second, older Chinese astrological system that maps a natal chart across 12 life palaces (career, wealth, relationships, health, and more) populated by 14 main stars. Auspio builds a full Zi Wei natal chart alongside your Ba Zi chart and harmonizes the two into one combined reading, rather than treating them as separate, disconnected reports.

Auspio computes solar terms and new moons with real astronomical algorithms rather than static lookup tables, and its calculation engine is validated against published almanac anchors — solar-term instants, Chinese New Year new moons, leap-month placements, and known day-pillar (ganzhi) dates. The underlying Ba Zi and Zi Wei logic is cross-checked against classical references rather than invented.

Yes. The core auspicious date finder is free to use. Auspio Premium ($4.99/month or $39.99/year, with a 7-day free trial) unlocks the personalized Daily Luck dashboard, your full Zi Wei natal chart and decade-by-decade timeline, the combined Ba Zi + Zi Wei harmonized reading, and family compatibility comparisons.

Yes. You can add family members or a partner and compare Ba Zi and Zi Wei compatibility (合婚) between two people — including branch-relation analysis (six-harmony, clash, triad) and how each person's chart complements the other's.

Yes. Auspio runs fully in English or fully in Simplified Chinese based on your device's language setting — no mixed-language screens. The Chinese name 吉日 (jí rì) remains as a secondary, heritage mark of the app.

Auspio is a native iOS app built with SwiftUI, requiring iOS 16 or later. It includes a home-screen widget for an at-a-glance daily luck reading.
