Compare any two birth charts with the real aspect math — composite, midpoints, cross-aspects. Built for compatibility reading without the templates.

Solar return chart calculated at your relocated coordinates, with the practical interpretation prompts. Secondary progressions, profections, and a tidy export for client files.
Astrolog ships in English, Spanish, German, French, and Polish — interface, interpretations, and client-facing exports all localized. Pick a language and read the same chart.
