The real issue

Why Compatibility Apps
Get You Wrong

"You're a Scorpio, they're a Taurus — opposites attract!" That's not compatibility. That's two data points out of dozens, dressed up as insight.

Your Sun sign says almost nothing about how you two actually work. Whether you feel safe with each other lives in your Moons. Whether you can talk through a fight lives in your Mercurys. The pull, the heat, the friction — Venus, Mars, Saturn, the angles between them across both charts.

A sun-sign app can't see any of that. Synastry can. It compares every planet in your chart against every planet in theirs — the same method an astrologer charges $150 for.

The full picture

What Synastry
Actually Sees

We compute both of your birth charts with Swiss-Ephemeris precision, then read the contacts between them — the cross-aspects that decide how two people land on each other.

The result is one honest number (not an everyone-gets-90 flattery score), four sub-scores for attraction, communication, emotional connection and stability, and — if it's there — a karmic signature for couples whose charts carry a sense of destiny.

Then the reading explains the why behind each number, in the same warm, direct voice our birth-chart readers are known for.

Common questions

Before You Begin

Select 12:00 PM. About 80% of a compatibility reading — the planet-to-planet contacts that drive attraction, communication, and emotional fit — doesn't depend on birth time at all. Only the house overlays and Ascendant get approximate, and the reading leans on the parts that stay solid.
Not at all. The reading is about the dynamic between two people — patterns most couples recognize whether or not they "believe." Plenty of skeptics read theirs and go "okay, that part's uncomfortably accurate." You don't need their permission, just their birth details.
Yes — completely. Synastry math is identical for any pair, and the writing is gender-neutral by design: it refers to each of you by name and reads every dynamic from your charts, never from gender or assumptions about who plays which role.
Absolutely — a compatibility reading is one of the most personal gifts there is. Enter both birth details and your own email, then forward the PDF (or read it together). A dedicated gifting flow is coming.
Totally fine. That said, the "How to love each other" and "Talk together" parts land best read side by side — a lot of couples go through it over coffee or a glass of wine. It's written to be shared, not kept secret.
Yes. Both people's birth details are used only to compute the charts. We never share, sell, or use your data for marketing, and you can request full deletion any time at support@cosmicblueprint.co.
