Real ephemeris computation
Built on the global standard models VSOP87 (planets Mercury to Pluto) and ELP2000-82 (the Moon’s perturbed orbit) via astronomy-engine. Ecliptic longitudes, latitudes and velocities are computed in real time with sub-arcminute accuracy — stationary and retrograde motion shows directly in the geometry.
Full multi-dimensional synastry
Inter-aspects between ten celestial bodies, plus lunar nodes and ascendant when birth time is known. Dynamic orbs separate exact (0–2°), strong (2–5°) and peripheral influences (up to 8° for the luminaries), weighing harmony against tension.
Calibrated scoring model
Real relationships are never 100% friction-free or 0% attraction. A statistically calibrated curve with a dynamic floor and ceiling (58–98%) gives every couple an honest, differentiated profile — not a generated feel-good score.
Instant and private
The engine runs in a fast edge environment. Birth data is processed in memory to calculate the angles and is never stored in ways that compromise personal privacy under GDPR.
