The Synastry app analyzes your birthday astrological chart and calculates the aspects of the planets at the current moment. It notifies you when a new transit affects you and gives you an explanation.
The numbers next to the aspects are DEGREES. When the number is zero it means that then the aspect is taking place.
The aspects square and opposition are shown with red color and the conjunct trine and sextile with green. The apps interpolates the background color so the aspects near zero degrees are colorful and they fade as the planets move away.
