Read the full description
Many families still live by the lunar calendar: death anniversaries, Lunar New Year, full moons. • Remember together: add a date once, the whole family is reminded on phone, web, watch or Telegram. • Do it right: a shared plan, the right prayer and custom. • Trust it: cited sources, a calendar checked against NASA and the Paris Observatory, open data with a DOI. • Understand it: Tử Vi, I Ching, feng shui, astrology and Tarot explained as traditions, with what is not proven.

Partial The reminder app, multi-platform sync, and lunar date conversion are buildable with existing libraries, but the value depends on curated, culturally accurate customs and prayers backed by cited sources, which needs domain expertise.
What it would actually take: The app itself is a standard stack: lunar-calendar conversion via an open library, a shared-family data model, and notifications through push, watch, and Telegram bots. The hard part is the content: vetted customs, prayer texts, and citations that must be accurate across regional traditions. Building a credible version requires subject-matter researchers or advisors, not just engineering.
