Astrological charting application
Casts traditional wheel charts—Mundane, Natal, and Transit—each in its own window with a live settings panel beside the wheel. Set the zodiac, coordinate origin, reference plane, orientation, and house system, plot up to 25 celestial bodies, then step the chart through time in units from seconds to years.
Learn more →Aquila is a desktop application that generates tables of astrological/astronomical events with stunning speed and accuracy thanks to the highly optimized search algorithm under the hood.
Gain the bird's eye perspective that you need to quickly determine critical dates and periods of time by utilizing Aquila's diverse set of study types that cover a vast range of astrological and astronomical phenomena.
Compass is a desktop application for casting traditional wheel charts at the heart of astrological practice: Mundane, Natal, and Transit. Each chart opens in its own window, so you can keep several on screen and compare them side by side.
Every control sits beside the wheel rather than behind a dialog. Change the frame, the bodies, or the aspects and the chart repaints immediately—so reading a chart and refining it become the same motion.
Built for astrological research, Cygnus is a high-precision desktop application for generating ephemerides. It computes planetary positions across any date range, delivering publication-grade tabular data you can trust for serious work.
Choose from multiple calculation perspectives including geocentric, heliocentric, and topocentric viewpoints, each available in standard and aspect variants, giving you the flexibility to approach your research from exactly the angle you need.
Pay once and own forever. Every purchase is backed by a 15-day, no-questions-asked money-back guarantee, and you will be up and running in a matter of minutes thanks to our automated licensing system.
