Astrology compatibility from two birth charts
Compatibility by sun sign says very little. Synastry compares two charts planet to planet and shows what draws you together, where friction appears and what helps.
What synastry is
Synastry is the comparison of two natal charts. An astrologer looks at how one person's planets connect with the other's: conjunctions, trines, squares and other aspects. The closer and softer the links, the easier it is for two people to understand each other.
What AstroWhisper shows
The bot explains in plain words what brings you closer, where it can be hard and what helps. It compares the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn of both people and names the strongest links.
You can add a partner, a child, parents, a friend and even a pet. A pet needs an exact birth date.
Where a couple would live best
At the end of the reading the bot picks two or three cities where favourable planets sit on the chart angles for both of you and explains why each city suits each of you. You can check any other city in Where is best for me.
Good to know
Compatibility needs birth data for both people. If a partner's birth time is unknown, the bot says so, notes that accuracy is lower and does not pick cities.

Frequently asked questions
How do I check compatibility by birth date?
Open the AstroWhisper bot, enter your own details, add a person in Loved ones and tap The two of us. The bot compares the two natal charts and describes the links.
Why is synastry more accurate than sun sign compatibility?
Sun signs only cover the Sun. Synastry compares all the main planets of two charts, so it sees more: for example matching Moons or friction between Mars and Saturn.
Can I check compatibility with a pet?
Yes, if you know its exact birth date. The bot compares the pet's chart with yours. Cities for the pair are not chosen in this case.
