Unique

Relationship astrology from full birth data and synastry, not sun-sign quizzes.

Problem

Most “compatibility” apps stop at sun signs. Real relationship astrology needs birth date, time, and place, then language people can actually use, not a dense professional chart dump.

What it is

Birth-chart and synastry readings for relationships:

  • Compatibility from full birth data, not sun-sign quizzes
  • Natal chart views and relationship / bond readings
  • History of past readings on device
  • Cosmic Pro: unlimited readings, all relationship types, full reading plus daily cosmic insights

Approach

Collect real birth inputs → compute chart / synastry → return a readable reading. Monetize depth (unlimited + full output), keep the first experience clear.

Outcome

People get a relationship reading grounded in actual charts, not a horoscope meme.
