Classical Astronomy Astrology

About Classical Astronomy Astrology

Most astrology apps ask you to believe. This one shows its work.

Classical Astronomy & Astrology is built for the revival: whole-sign houses, sect, annual profections, zodiacal releasing, the Lots, the seven classical planets, the ancient art of Ptolemaic and Hellenistic astrology, auditable line by line. One deterministic engine runs it all: a custom double-epicycle ephemeris for the sky, JPL Horizons for the charts.

THE ENGINE COMPUTES. THE AI EXPLAINS.
A deterministic classical engine computes your chart's testimony, 1,171 authored components against 2,373 conditions, so the same chart returns the same reading, word for word, every time. No AI writes your reading.

Then, if you want to talk it through, the optional AI Astrologer answers questions, using only what the engine already computed. A model with no chart has nothing to invent a placement from. It recalls the tradition; it does not compose it.

ASK YOUR CHART
Ask what your chart lord is doing, the condition of any house lord, your Lots, this year's profection and Lord of the Year, your releasing periods, a bond across twelve classical lenses, or what transits are doing to your nativity. You get a real argument from your placements, receipts attached. When the tradition is silent, it says so. Your first reading is free, and an answer it can't ground back to your chart costs you nothing.

IT SHOWS THE MATH
The planets move on nested circles of deferent and epicycle, the Ptolemaic model held for fourteen centuries. Stand under the dome, point your phone at the sky, or watch the orrery turn at five speeds.

IT CITES ITS SOURCES
Every verdict names the placement it rests on and the source it comes from: Ptolemy's Tetrabiblos, Dorotheus, Valens, Māshāʾallāh and the tradition that carried the art from Hellenistic Egypt through the Persians and Arabs. Tap any section for the working underneath.

IT TEACHES THE METHOD
Terms are underlined: tap for a definition, hold for the full sourced entry. A free fifteen-lesson course walks the doctrine through a live chart, in the order the ancients taught.

YOUR BIRTH CHART
Cast as the tradition casts it: whole-sign houses, five classical aspects, the five essential dignities, sect, solar conditions, and the royal fixed stars. Then your chart ruler, temperament, strongest and weakest planets, and three Lots.

YOUR YEAR AHEAD
In the order the ancients ranked it: primary directions first, then profection, solar return, eclipse activations, and confirming transits. When techniques agree, the app says so. When they don't, it says that too.

COMPATIBILITY & SYNASTRY
Classical synastry across twelve relationship lenses: marriage, business, mentor, parent and child, and more, scored on the same contacts. Not sun-sign matching.

THE PDF LIBRARY
A natal report of 30 to 50 pages with seven appendices, typeset like a book. Twelve bond readings plus a synthesis, and a chart sheet free to share, all made on your phone.
