I like to teach astrology from a Whole House perspective, but I would like to give you some resources to get your free natal astrology chart.  You can find your free Whole House Astrology Chart here.  You can also get a copy of your Placidus House Natal Chart here.  If you are looking to invest in software I would highly recommend Time Passages.  They offer a phone application that is very affordable.  If you are would like to get a copy of your Human Design chart, I highly recommend Genetic Matrix.  They offer a free Human Design chart, but also have a paid service where you can get a chart that I worked with them to build that I like to call the Astro HD chart where it incorporates the astrology house systems into the Human Design chart to improve the understanding of how the gates differ from chart to chart.  They also have a Human Design Calendar that shows which gates are transiting along with compatibility charts, a dating service, return charts and more.

Make sure to check out other Astrology, Human Design and HD Astro resources.  Also get your free Human Design Chart.
