Frequently asked questions
How is compatibility worked out?
By the angle between the two signs on the zodiac wheel — the classic astrological aspects. Signs 120° apart (trine) flow most easily; 90° apart (square) create friction that can also spark growth.
Can a low match still work?
Of course. Sun signs are only one part of astrology, and real relationships depend on the people, not the stars.
Is this a real prediction?
No. This tool is for entertainment only. It is based on traditional astrology and folk customs, not science, and should not be used to make important decisions about health, money, relationships or the law.
Is Zodiac Compatibility free?
Yes. Zodiac Compatibility is free to use with no sign-up and no watermark.
