Meet Synastry.

The name and the product
In astrology, synastry is the comparison of two birth charts to explore relationship themes. Synastry is also the name of this product, whose official website is synastry.my.
Sableon LLC publishes Synastry. Our calculation methods, public birth-information sources and correction process explain what goes into each chart and where uncertainty remains.
The company and founder
Grayson Thomas founded Sableon LLC, the software company behind Synastry. Sableon builds products around self-understanding, compatibility and human connection.
Synastry brings chart calculations, explanatory guidebooks and personal exploration into one experience. Our methods page explains the calculation engines and sources, including where public birth information remains uncertain.
Explore privately, learn openly
The free birth chart, two-chart synastry, current transits, numerology, astrocartography and tarot tools can be used without an account. Celebrity charts and the astrology, numerology and tarot guidebooks are also open to browse. A free Synastry account adds a personal chart workspace and favorites.
Your personal account chart is separate from the public-figure catalog. The public profiles describe people whose birth information is available from cited public sources.
Sources and uncertainty belong beside the chart
A birth date, a family-reported time and a birth-certificate transcription do not carry the same certainty. Public profiles show their source context, identify uncertain birth times, and display alternatives when a position can cross a boundary.
The reference library explains symbolic traditions and calculation conventions. Those interpretations are offered for education and reflection, not as scientific personality assessments or guarantees about life events.
The website and the app
The website offers birth charts, transits, Western and Vedic settings, birth-Moon phases, Pythagorean and Chaldean numerology, astrocartography city readings and public-figure comparisons. Free birth chart, synastry, transit chart and horoscope, numerology, astrocartography and tarot tools work without signing in. The custom 78-card tarot deck includes one-card and three-card readings, and numerology profiles show birth-card reflections. Adults 18 and older can create an account for saved personal tools and favorites.
The mobile app focuses on Chart, Friends and Tarot. The complete reference library also describes techniques that are not all calculated on the website.
