Type two names and get a compatibility percentage with a playful verdict. The formula is deterministic — the same pair of names always scores the same, in any order — so the result is "official" enough to settle any lunchroom debate. Purely for fun!
📌 For entertainment only! The percentage comes from a playful formula based on the letters in the names — real compatibility comes from communication, kindness and shared values, not from the alphabet.

The classic name game, upgraded
Long before smartphones, kids played this with paper: write two names, count shared letters, and follow a folk formula to a percentage. This calculator is the same idea with better math — a stable hash weights every letter by its position, so even similar names like Anna and Anne land on different scores. Because the names are sorted before hashing, it never matters who is typed first: the crush and the crusher always get the same number.
The score is pure entertainment. If you get 98%, congratulations on winning an alphabet lottery. If you get 8%, take comfort in the fact that no peer-reviewed study has ever linked letter frequency to lasting happiness.
It uses a letter-based formula: both names are normalized (lowercased, letters only), sorted so the order you type them in never matters, and run through a stable mathematical hash that weights each letter by its position. The result is mapped to a 0–100 percentage. It is completely deterministic — no randomness is involved.
No — and it is not meant to be. It is a game, the digital descendant of the paper-and-pencil "LOVES" game from school days. The percentage measures nothing except how two names interact with an arbitrary formula. Real compatibility comes from communication, respect and shared values, none of which are spelled in a name.
Yes, by design. The formula is deterministic, so Emma + Liam gives the same percentage today, tomorrow and on a friend’s phone. The order does not matter either — Liam + Emma gives the identical score, because the names are sorted before the calculation.
Yes. After you calculate, the two names are stored in the page URL, so copying the link (or using the share buttons below the calculator) sends the exact same result to whoever opens it. That is a fun way to break the news of a 94% match — or a 12% one.
No. Everything happens in your browser — the names are never sent to a server or saved anywhere. They only appear in the URL on your own device so that you can share the result if you choose to.
