Trine is a synastry discovery engine that uses your complete birth chart to find compatible matches globally. It analyzes 81 planetary aspects beyond just Sun, Moon, and Rising signs.
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.
You can generate custom synastry reports that cover multiple areas of compatibility, tailored to your mutual aspects and signs. These reports can be shared directly from the app.
Yes, Trine features 'The Study,' an in-app library that explains astrological concepts like aspects, orbs, and planets, catering to all experience levels.
Trine has an age rating of 17+, indicating it is suitable for mature audiences due to its focus on relationship dynamics and astrological interpretation.
