Astrologer vs Planetdance

Planetdance, by Jean Cremers, is one of the most surprising programs in astrology: free, yet packed with features, extensible through a scripting community, and constantly updated. Its trade-off is a dense, classic-Windows interface and Windows-only delivery. Astrologer covers the everyday professional techniques in a modern browser workspace, also free, with interpretation and learning tools built in.
