Compatibility read from both birth charts, not from sun signs
One-time purchase. Enter your details on the next step.
Our synastry analysis reveals the hidden dynamics of your relationship. We compare two natal charts aspect by aspect and score four dimensions - love, communication, passion and longevity.
The argument that keeps coming back
“We are having the same argument for the third time this month”
Challenges
Which exact aspect between the two charts sits behind the recurring argument, and what to do with it.
“I cannot tell if we are incompatible or if this is fixable”
Four separate scores
Love, communication, passion and longevity are scored separately. Low communication with high passion is a diagnosis, not a verdict.
“He is a Leo, which tells me nothing”
Aspects between the charts
A sign splits people into twelve groups. Here the two full charts are compared by date, time and place.
What the reading for two contains
Every section below is part of the reading. Nothing here is an add-on.
- Both natal charts: yours and theirs, calculated separately
- The aspects between the charts: which planets touch, and how strongly
- Four separate scores: love, communication, passion and longevity
- The overall picture: where the two of you fit together
- The challenges: which exact aspect sits behind the argument that keeps returning
- Longevity: what holds the relationship beyond the first attraction
- Advice built on your own aspects, at least three, each tied to a specific contact
A passage from a reading for two
Sample passages, written for an example chart. Your text is built from your own placements, so it says different things.
A Mercury square between the two charts means one of you speaks in feelings and the other in facts, and each hears from the other exactly what was not said. That is not a lack of love, it is a different language. The argument breaks if one of you says out loud what they heard before answering.
One partner’s Saturn touches the other’s Moon. Bonds like this start heavier and last longer than most: there is a sense of responsibility that does not disappear when the infatuation fades. The cost is that one of you will sometimes feel the other as a demand rather than as support.

What is Synastry?
Synastry is an ancient astrological technique that compares two natal charts to reveal the dynamics and compatibility between two people. The word synastry comes from Greek and literally means "with the stars".
By analyzing the aspects between the planets in both charts - how your Sun interacts with their Moon, how your Mars resonates with their Venus - synastry reveals deep truths about your relationship: areas of natural harmony, challenges for growth and the long-term potential of the relationship.
Frequently Asked Questions
What is synastry?
Synastry is a technique in astrology that compares two natal charts to reveal the dynamics of the relationship between two people. Through analysis of the aspects between the planets in both charts, synastry reveals the strengths and weaknesses of the relationship, areas of harmony and challenges.
What exactly do I get in the report?
The aspects between both charts - which planets touch and what each one sets off; a score across four dimensions (love, communication, passion, longevity) with the reasoning behind it; the places where you diverge; and concrete advice on what to do about them.
Can I do synastry with a friend, not just a partner?
Absolutely! Synastry works for any type of relationship - romantic, friendly, family or business. Each type of relationship has different emphases in the analysis, but the principle is the same - revealing the dynamics between two souls.
Do I need ready-made natal charts?
The date, time and place of birth are needed for both people. Ready-made natal charts are NOT required: enter the data directly in the form and the charts are calculated for you. If you already created a chart with us, simply pick it from the list.
How accurate are synastry analyzes?
The accuracy of a synastry analysis depends on the accuracy of the birth data. We use the professional standard for astronomical data (Swiss Ephemeris) for the most precise calculations and expert interpretation based on thousands of astrological sources. Synastry reveals the potential of the relationship, but does not determine its fate.
About the synastry
My girlfriend and I ran our compatibility out of curiosity. I expected cheesy 'perfect match' clichés, but it pinpointed exact details—where our communication stumbles and what we clash over most often. It gave us plenty of good stuff to talk through.
We ran compatibility for my business partner as well as my relationship. It gave us really interesting insights into team dynamics and where to be mindful during financial decisions.
