What Do the Different Lines on the Natal Chart Represent?

Black solid lines (iOS) or red lines (Android) represent a "Square" aspect. For example, if you see a black solid or red line connecting Saturn and the Moon, it indicates a "Saturn Square Moon" aspect. In astrology, a square refers to an angle of approximately 90° between two celestial objects, symbolizing a challenging or tense dynamic.

Black dashed lines (iOS) or blue lines (Android) represent an "Opposition" aspect. For instance, a black dashed or blue line between Saturn and the Moon means "Saturn Opposing Moon". An opposition occurs when two objects form an angle of approximately 180°, signifying another form of tension or conflict in the chart.
