Cast a chart.

The person
The moment
Date of birth
Type the year, or tap a decade then set month and day. Avoids the long phone date wheel.
An accurate time sets your rising sign, houses, and Moon degree. Don't know it? Enter 12:00 noon: the chart still works, but those placements stay approximate until you have a real time.
The place
Type the city, then tap Find — latitude, longitude, and timezone fill in automatically.
Chart options
Placidus is the modern Western default. Whole Sign is traditional Hellenistic and Vedic; Equal is the simplest; Koch / Regiomontanus / Porphyry are other quadrant systems.
Tropical is Western, anchored to the equinoxes and seasons. Sidereal is Vedic, anchored to the fixed stars themselves.

Frida Kahlo's natal is in the public roster: painter, Coyoacán, 1907. The wheel, the placements, the sentences. Same engine as yours.
