About SoulmateChart
By SoulmateChart Editorial ·
SoulmateChart is a free soulmate compatibility calculator. We help people answer one clear question: how do two birth charts interact when read as a synastry map?
Who writes the interpretations?
SoulmateChart Editorial maintains the calculator copy, FAQ answers, and synastry guides. Our standard is Western Tropical Astrology with whole-sign houses, major aspects only, and plain-language explanations — percentage first, jargon last.
What do we believe about accuracy?
Planetary positions are computed from birth date, time, and place. House overlays use whole-sign houses from the Ascendant; if birth time is unknown we use solar whole-sign houses and label them clearly. Advice is generated from the aspects actually found in your pair — not a fixed script. Results are for entertainment and self-reflection, not professional advice.
