How the Love Calculator Works
Enter two names and get a compatibility score between 0 and 100 %. Under the hood, the calculator combines both names and runs them through a deterministic hash function — a bit of math that turns text into a number. The same two names therefore always produce the same score, no matter when or where you try. Swap in a nickname, though, and the universe may have a different opinion.
The History of Love Testers
Name-based love tests are older than the web: schoolkids have played pencil-and-paper versions like "FLAMES" for generations, and arcade "love tester" machines date back to the 1920s. The digital version simply replaced the pencil with a hash function — the fun stayed the same.
What Actually Predicts Compatibility
Since you asked (or even if you didn't): relationship research points to things like communication style, shared values, humor, and how couples handle conflict — the psychologist John Gottman famously predicts relationship outcomes from how partners argue, not whether they do. None of that fits in a name, which is exactly why this calculator lives in our Fun category.
Share the Fun
Scores make great conversation starters. Screenshot your result, compare with friends, test your celebrity crush — and remember that a 23 % has never stopped a great love story, nor has a 98 % guaranteed one.
