Trine analyzes the angles ('aspects') between all planets in two birth charts, a method known as Synastry. It uses a statistical algorithm trained on 100,000 simulated birth charts to rank matches by combined aspect totals.
Yes, Trine features a 'Search-by-Aspect' tool allowing you to find users with specific planetary aspects, such as Mars trine Venus. There are 720 possible combinations to search.
Trine allows exploration within 0.5 miles ('At the Party'), within 25 miles ('Near You'), globally, or by searching specific cities like NYC, SF, London, and Tokyo.
