Ancient Art, Modern Match
Trine is a global birth-chart matching app. We match charts using complete planetary data, helping you find your most compatible matches around the world.
We look beyond Sun, Moon and Rising. Trine measures 81 planetary aspects to discover your strongest connections.
— Synastry —
Synastry is the traditional method for analyzing compatibility in astrology. It looks at the angles (aspects) between all planets in two birth charts.
Aspects correspond to certain relationship patterns based on the planets and signs involved.
The Aspects:
Conjunct ———–– 0° (Amplify)
Sextile ————— 60° (Support)
Square ———––– 90° (Challenge)
Trine —————– 120° (Harmonize)
Opposite ——— 180° (Polarity)
Planets: Sun, Moon, Ascendant, Mercury, Venus, Mars, Jupiter, Saturn, MC
— Features —
1 — Search by Sign, Search by Aspect
Search for users by planet placements (e.g., Sun in Aries, Moon in Taurus, etc.)
Search for other charts based on any aspect to your chart (e.g., Venus trine your Venus). Choose from hundreds of aspect combinations.
2 — Compare Charts With Friends
Have anyone scan your Trine-app QR code. Compare your chart with friends, family members, etc.
We'll ask their birthday, add them to your Charts, and show you both a full synastry report.
Those don't need an account – but can join from there!

Add custom charts and read about your synastry. Compare synastry reports between you and any other user.
Export reports as a PDF to share with your friends. Add anyone's birth chart, and read all about your connection.
If you need their bday or birth time, send them your QR code.
5 — Compatibility Tags
Every match provides individual aspect tags derived from real planetary aspects:
· Soulmates — Moon/Moon, Sun/Moon

· Power Couple — Sun/Mars/Jupiter
· Lucky — Jupiter & Moon/Venus, etc.

Tap any aspect tag to see the aspect behind it, plus conversation starters, and send a like based on the tag.
6 — Read the Wheel
Every match includes a synastry wheel: both charts drawn with every aspect between them.
Tap any planet for a reading of everything that planet touches in the other person's chart.
7 — Celebrity Matches
Find out which celebrities you're most compatible with. Our database includes hundreds of actors, musicians, historical figures and more. Pin your favorites to your profile.
8 — The Library
An in-app library explaining aspects, orbs, planets and houses. Everyone gets a chance to learn, no matter your experience.
— Our Method —
Trine ranks matches by their combined aspect totals, weighted by how exact each contact is.
We score 100,000 simulated chart pairings through the same model to build an random distribution, reporting your compatibility as a percentile against a statistical baseline. Every match is ranked as a true percentile in relation to your chart.
Our goal is to find your absolute most compatible matches around the world, combining ancient practice with modern technology.

This app has so many wonderful features and takes out the guesswork of finding a match 😍 I love that it goes deeper than surface-level swiping and actually considers astrological compatibility and connection. Such a fun and thoughtful concept for anyone into astrology, relationships, or meaningful conversations ✨
Best!
