Get a free astrology compatibility chart for two people. Enter both birth dates and see your compatibility score, key synastry aspects, and relationship strengths and challenges. No sign-up required.
This tool offers a faster way into compatibility than a full synastry chart, using just each person's Sun sign to look at element and modality dynamics between them, for example whether two fire signs amplify each other's energy or two earth and water signs balance or dampen one another. Enter both birth dates and you get a compatibility score along with a plain-language breakdown of where the pairing's natural strengths sit and where friction is more likely to show up. For a deeper look that accounts for every planet and exact aspect rather than just the Sun signs, the full synastry chart is the more detailed option.
