What You Can Do
Transits Bi-Wheel
Overlay current transits on your natal chart in a clear bi-wheel display. Live clock mode updates in real-time. Step through dates by day, month, or year.
Synastry & Composite
Compare two charts for relationship analysis with a cross-aspect grid. See composite midpoint charts for understanding the relationship itself.
Extra Bodies
Toggle Chiron, Lilith, North/South Node, and the four major asteroids (Ceres, Pallas, Juno, Vesta) individually on the chart wheel.
Dignity Rings
Visualise domicile, exaltation, triplicity, decan, and terms rulers as coloured rings inside the zodiac band — toggle each independently.
Predictive Timing
Secondary progressions, primary directions, zodiacal releasing, planetary returns, profections, firdaria, decennials, and bounded periods — all in one panel.
Techniques & Traditions
Built for both modern and traditional astrologers. Switch between orb traditions with one click — Hellenistic (Valens), Medieval, Modern, and more.
