About this app

Ji is a personal luck calendar that reads both astrological skies.

Most astrology apps show you a single zodiac. Ji layers four time-tested systems over every day of your life, for a far richer picture of what each day favors:

• Western (tropical) astrology — the familiar zodiac and horoscope
• The true sky (sidereal) — a 13-sign system including Ophiuchus, mapped to an ancient 13-month "Annus Lunaris" calendar
• The Chinese almanac — the 28 lunar mansions and Four Celestial Symbols used for centuries to choose auspicious days (擇日)
• Numerology — your personal and universal day numbers

Your natal chart is computed on your device and read against each day to show what's supported and what to be cautious of — in plain language, not raw jargon.

Features
• A dual-zodiac calendar — the real sky and the everyday sky side by side; spot your most favorable days at a glance
• Daily reading ("Tyche") — a literate oracle that cites real historical texts, or plainly says when the texts are silent (never invented)
• Natal chart — both zodiacs, rising sign, and birth lunar mansion
• Luck journal — log how your days actually go and uncover your own patterns over time
• Two beautiful themes — a light printed-almanac skin and a dark, gilded "Empyrean" skin
• English and 中文
• 100% private & offline — no account, no sign-up; your birth details never leave your device

Ji speaks in favors and cautions, never guarantees — a lens for reflection and timing, offered for insight and entertainment.

Find your lucky day.
