What is a synastry chart?

Synastry compares two birth charts: it looks at the angles between one person’s planets and the other’s. Each link has a nature (flowing, tense or a blend) and a strength, set by how close it is to exact.

We list every link with what it feels like between you and one practical tip. Couples get warmer wording, and friends and family get wording with no romance in it.

Birth chart compatibility, honestly

No chart says two people are right or wrong for each other. The label at the top only counts your flowing and tense links. The detail below is where it gets interesting.

The link you send carries planet positions, never a birth date, time or place, and it opens on their phone. We never receive either of your details.
