How do you really match?
Not just your Sun signs. Your Moons, Venus and Mars, and the strongest contacts between your two charts.

Questions
How is this different from Sun sign compatibility?
Sun signs are one of ten planets. This tool compares both full charts: your Moons (how you each feel safe), Venus and Mars (attraction and drive), and the strongest planet-to-planet contacts between you. Two Leos can match very differently.
Do I need both birth times?
No. Without times you still get the Sun, Moon (if it didn't change sign that day), Venus and Mars comparisons. Times add the rising signs and make the Moon certain.
Is it free?
Yes. The score, the four main factors, and your strongest easy and hardest contacts are free. The $12 deep dive covers every contact and the months ahead for the two of you.
