Fixed Stars - NEW -
Exploring Fixed Stars and their relationship to a particular chart has never been easier than it is in the new Io Edition. Simply drag a chart file from your list of saved charts to the Fixed Stars page and drop it. You instantly see the star set you have selected as they relate to that chart. Print or Save the results as a convenient PDF file, even email it directly from your program. It could not be easier.

Arabic Parts - NEW -
Because of its growing popularity among astrologers worldwide, we have added an Arabic Parts function to Io Edition. Select the Planets and Aspects you wish to view, choose how you wish to sort and view them and you have it! Change your selections while viewing the results and instantly view the changes. This feature makes it easy to see exactly what you wish to see without complex manipulation. User Friendly - that is an understatement.
