Questions people ask
- How is the compatibility score calculated?
- Sign-only mode compares elements, modalities and rulers. Full mode compares planets between two charts.
- Is a high score a guarantee?
- No. A score describes tendencies. Real relationships depend on much more than a chart.
- Do I need birth times?
- Not for sign-only mode. Birth times add the Moon and rising signs.
