Love Compatibility Calculator
Check your crush compatibility using name, birthday, and personality traits. Fun and shareable — not scientifically accurate.
Your Compatibility Result
How It Works
Three methods blend into one fun compatibility score.
FLAMES Algorithm
Cross out common letters between names, count remaining ones, and cycle through F=Friends, L=Love, A=Affection, M=Marriage, E=Enemies, S=Siblings to find your label.
Birthday Numerology
Each birthday reduces to a single-digit life path number. A 9x9 matrix maps how two life path numbers vibe together — ancient system meets modern fun.
Personality Matching
Pick 3 traits each. The more traits you share, the higher your personality match. Shared traits like "adventurous" or "creative" boost your score.
