Kairon intends to be simple and powerful both at the same time. It wants to come close to a handdrawn chart. Therefore the user may select and deselect as many planets and aspects as there are, independently between the inner and the outer planets in synastry like charts.
Our Review: Kairon allows you to create star-charts in the form of Zodiac charts or grids. Although I can't profess to understand the star-charts themselves I was impressed at how many features and customisations that Kairon includes. Charts can be modified to be of different 'houses' and input information is accepted to modify astrology star positions. The chart can be viewed as per star formations from 1586 - 2131AD. If you have an interest in synastry and starcharts then Kairon seems a very good bet.
