Recently I’ve found out about What Watch – a freeware astrology software built on the Swiss Ephemeris.
“What Watch is a powerful tool that covers many areas and techniques of astrology. Its purpose is to get quick access to relevant information and displaying it in a concise and no-nonsense way: Keep it simple while providing all that is necessary. What Watch assumes that you’re already familiar with some basics of astrology, and has an extensive tutorial. explaining how to use the astrological techniques implemented here.
What Watch draws and prints chart wheels, including synastry and composite, draws tables of essential dignities, calculates element and quality balances and allows analysing birth aspects using a “harmonic aspectarian”. It is also a tool for the experienced astrologer who wants to follow closely transit, progression and solar arc cycles, including transits on composite charts. The program creates ephemeris lists for any given combination of planets providing dates of the transit itself, of stations and of sign changes.
Advanced modules include search and analysis for groups of charts, a 3D globe for relocation and maps similar to Astro*Carto*Graphy. All features are explained in a built-in tutorial.”
