Compatibility is more than a number
Read the connection, not just the score
Every relationship has harmony and friction. A good synastry reading gives you language for both: a strong score stays a starting point, and a hard aspect stops feeling like a verdict.
The aspects behind it
Move from a headline to the planetary pattern that created it. The why matters as much as the what.
Green flags and friction
Warmth and tension can sit in the same chart. Read both with care and bring the insight into a real conversation.
A small ritual, made simple
From first detail to deeper insight.

Use insight with agency
Synastry can suggest a question or a strength. It cannot make a choice for you or replace direct communication.

Synastry, explained for real relationships.
What is a synastry chart?
A synastry chart is two natal charts read together. Your planets are overlaid on your partner's houses, and theirs on yours, revealing where your energies meet, support, and challenge each other. Synastry compatibility turns those overlaps into a shared language for how you relate.
The synastry aspects that matter most
Some aspects create warmth: a Moon trine, a Venus sextile, a Sun conjunct Moon. Others create friction that can also create chemistry: Mars square Venus, Saturn opposite the Sun. A good synastry reading names both, so a connection's tension is something you discuss instead of something you survive.
Synastry vs. composite chart
Synastry shows how two people interact: the spark, the ease, the friction. A composite chart is a third chart calculated from the midpoint of both charts, representing the relationship itself. Astro Mate reads charts in pairs rather than blending them into one, because the connection stays about two real people, not an abstraction.
What the four compatibility scores measure
Attraction covers the chemistry between you, communication the ease of conversation, love the emotional bond, and long-term potential the staying power. Reading the four together gives you a fuller picture than any single percentage.
Good questions are good signs
Before you follow the thread.
What is synastry dating?
Synastry dating uses two natal charts to explore relationship chemistry. Astro Mate compares planetary patterns and presents the result through attraction, communication, love, and long-term scores.
How accurate are synastry scores?
Scores are a structured interpretation of chart patterns. They are useful for reflection, but they are not scientific predictions or a final measure of relationship success.
What birth details are needed for synastry?
You need the birth date, birth time, and birth place for the most complete comparison. If a birth time is unknown, some house and rising-sign details may not be available.
Which synastry aspects show attraction?
Venus–Mars contacts are the classic chemistry marker, with Moon–Mars and Venus–Venus close behind. Soft aspects tend to feel easy and warm, while harder aspects can show up as intensity that needs clear communication.
Can synastry tell me if a relationship will last?
No. Synastry describes patterns between two charts, not outcomes. Long-term success still comes from communication, values, and choice. The chart is a map you draw on, not a destination.
How do I get a synastry chart with someone?
Add your birth details and your partner's birth details to Astro Mate and open the compatibility view. You will see the four scores, the aspects behind them, and a plain-language reading of what the connection looks like.
