Astrology professional? Prepare quickly for your next client. Set your preferred orbs and focus. Build up an aspect picture of a given natal chart by selecting only those aspects that you determine are most important, and filter out the rest to avoid distraction and information overload. More than any other astrological measurement app, Stellar Analyst is designed to avoid unnecessary information so that your eyes and brain can quickly and easily integrate the left-brain measurements you need in order to let your right brain drive the bus during client consultations. No more printing out pages and pages of lists, bi-wheels, and tri-wheels. Dial up a date, step it forwards and backwards and watch as your selected planets come into orb, become exact, and move out of orb - for all transits, secondary progressions, and solar arcs - allowing you to build an intuition of recent past and near future influences on your client without unnecessary clutter and distraction. Want to know the last time your client had Uranus cross an angle? Dead simple. Want to explore a major event from 15 years ago that comes up during consultation? Immediately get to that date and see all the influences in play on-the-fly. Don't waste a single minute. Try Stellar Analyst today.
