Why this differs from Co-Star and free apps

AstroVia natal reports use the tropical zodiac and the Placidus house system. Many free apps mix systems or hide which one they used, so the same birth data can produce a different wheel.

Tropical astrology measures signs from the Earth's seasons. Sidereal astrology measures them from the stars. The two frames drift apart over time, so a planet can fall in a different sign depending on which one you use.

Co-Star and similar free apps often lead with Sun-sign content. A full natal report here is written from the calculated chart: planets, houses, and aspects.
