La So AI: Vietnamese Astrology

La So AI casts a Zi Wei Dou Shu (Purple Star) birth chart from your date and time of birth, then interprets it with AI in clear, readable language.

TWELVE PALACES — FREE
Enter your birth date and time (solar or lunar calendar, leap months supported) and your gender. The app builds the full chart: major and minor stars placed, Life Palace and Body Palace identified, all twelve palaces laid out. This calculation is free and unlimited.

AI INTERPRETATION
• Single palace — a deep reading of any one of the twelve palaces. Key palaces (Life, Wealth, Career, Spouse) cost more credits than minor ones (Siblings, Friends, Parents).
• Full report — all twelve palaces, six cross-palace readings, six themed essays and one overview.
• Major cycle — how a given ten-year period unfolds.
Every reading is generated from your own chart, not a generic zodiac-sign article.

PERPETUAL CALENDAR
A perpetual almanac: convert between solar and lunar dates, look up heavenly stems and earthly branches, auspicious days and auspicious hours. Free.

SAVE AND SHARE CHARTS
Sign in with Google, Apple or email to save charts, revisit them across devices and share a chart with someone by link.

HOW CREDITS WORK
Calculation — star placement, the chart itself, the calendar — is free. Only AI interpretation costs credits. New accounts receive 20 credits after verifying a phone number. Buy more in-app:

• Starter pack — 40 credits, enough for one Life Palace reading.
• Full Report pack — 199 credits, enough for one complete chart report.
• Family pack — 800 credits, enough for four full reports.
• Extended Family pack — 1,400 credits, enough for seven full reports.

Each pack's price is shown on the Top-up screen in the app. These are one-off purchases: no subscription, no auto-renewal.

MORE
• A home screen widget: solar date, lunar date, stems and branches and today's events. The large size shows the whole month.
• Light and dark themes.
• Fortune notifications, switched on or off under Profile.
• No in-app display ads.
