The date, the minute, and the place.

What you enter

1. 1
   Date of birthAny date from 3000 BCE onward — an ancestor's chart is the same calculation as yours.
2. 2
   Time of birthTo the minute. The Lagna (ascendant) changes sign about every two hours, so this decides which house every graha lands in.
3. 3
   Place of birthPicked on a map, not typed and hoped for — the village next to the city is a different chart.

What the app does with it

• The place you picked becomes latitude and longitude, and the sky is computed from that point on the earth.
• The clock is set to the time zone in force there on that date — not today's. Zones were redrawn, and so was summer time.
• Positions come from the Swiss Ephemeris, the same data professional astrology software runs on.
• Everything is read sidereal, with the Lahiri ayanāṃśa — the Indian civil standard.
• All of it happens on your phone. The ephemeris ships inside the app, so no server is asked where you were born.

What you get

One chart opens into nine tabs — the daily reading first, the working behind it second, and the classical depth after that.

• Phalita
• Phalaśruti
• Janmāṅkam
• Rāśi Chakra
• Graha Bala
• Vargas
• Viṃśottarī Daśā
• Gocāra
• Jñānī

Phalaśruti is the one to look at first: for every line of your reading it shows the datum it came from, the rule applied, and the classical reference.
