About Birth Charts
What we do
Birth-Charts.app is a free celebrity astrology and compatibility database. We cover 2,000+ public figures with detailed birth chart profiles, sun sign analysis, and synastry compatibility reports across all 78 zodiac sign pairings.
Our approach
Every compatibility report is grounded in Western astrological mechanics — elements, modalities, planetary rulerships, and aspects. We focus on specificity over generic flattery, so you get honest analysis of both strengths and challenges for each pairing.
Cosmic Compatibility app
