Astrologer vs io Edition (Time Cycles)

io Edition, from Time Cycles Research, is a long-standing professional astrology program with deep roots in the Macintosh world, known for its typographic chart presentation and its place in established practices. As of 2026 the official Time Cycles Research site is offline — its domain is now parked for sale — and the program appears to be discontinued, so it is no longer a practical choice for new buyers. Astrologer is an actively developed browser workspace with interpretation and practice tools built in.
