About AstroSanmei
AstroSanmei is a divination and character experience app set in a world where legendary historical figures have been reborn into an advanced feline civilization.
In this world, a civilization of cats possesses the power to summon outstanding souls across 3,000 years of human history. These reborn souls attend the Royal Catgirl Academy, where they grow into the leaders who will shape the future.
Using NASA JPL's DE440/DE441 ephemeris data, AstroSanmei can generate accurate Sanmeigaku readings for anyone born between 601 BCE and 2400 CE. Gender-free by design.
