Hermetic Systems
Offers 'Planetary Aspects and Transits' - a nice, simple program. Unlike the usual astrology programs, this software makes hardly any mention of astrological signs, and no mention of houses, but rather concentrates (as its name says) on planetary aspects and transits, and how these change over time.

Janus Astrology Software
Janus has all of the standard calculation features expected of a top of the line astrology software program, including natal and transit reports, astro-mapping, Arabic Parts, fixed stars, progressed charts and return charts. It also has specialist modules for Cosmobiology, Uranian Astrology and Medieval Astrology, and includes the medieval calculations for Firdaria and Profection. This site includes a free trial version which allows you to evaluate and use all of Janus 3's operational features for a period of 60 days.
