Enter two names and get an instant “love match” percentage — an overall score plus a Passion / Friendship / Trust / Communication breakdown, as a shareable card. Fully deterministic (the same pair always gives the same result), purely for fun, nothing stored.
Love Compatibility Calculator
For fun only — a playful, deterministic word game, not a real compatibility test.
How to use
Enter two names
Type your name and theirs (English or Chinese). Order doesn’t matter — A with B and B with A always give the same score.
Tap “Calculate”
You instantly get an overall match plus a Passion / Friendship / Trust / Communication breakdown. The algorithm is fully deterministic: the same pair gives the same result, every time, for anyone.
Share your card
Tap “Download” to save the image or “Share” to send it — and compare scores with friends or your crush. Purely for fun, with a wink.
Love Compatibility Calculator: a playful name game
“How compatible are we, really?” is a question someone always wants an answer to. This calculator answers it the fun way: type two names and it returns a 0–100 “match” percentage, broken down into Passion, Friendship, Trust and Communication. It is, of course, not science and won’t actually predict a relationship — it’s a little game that makes you smile and dare your friends to beat your score.
How it’s calculated (and why it’s the same every time)
The key word is deterministic. Many online “love calculators” spit out a different number every time you refresh — that’s just a random number, and it gets boring after one go. This one is different: it normalises the two names (lowercases them, trims spare spaces), sorts them alphabetically (so A+B and B+A are identical), and runs a fixed hashing algorithm to map that pair to four sub-scores and an overall. That means the same pair gives the same result — today, tomorrow, for you, for your friend. That’s exactly what makes it good for comparing: you and a friend can each test your match with the same person and the scores are reproducible and side-by-side.
“It doesn’t measure fate — it’s one consistent little number about two names.”
Where “name compatibility” comes from
Scoring compatibility from names is an old pastime. The classics are the English “FLAMES” game and countless “love calculators”; Chinese culture has its own traditions of matching by stroke count, zodiac and birth signs. Their shared appeal is simple: a name is the most personal symbol we have, and putting two names together to “test” them carries a little romantic ritual. This tool uses no fortune system at all — just a pure text algorithm that returns a stable, fun score. Its value is in being fun, shareable and comparable, not accurate.
Please treat it as a game
One thing said plainly: this is entertainment. Whether a relationship works depends on real time together, communication and effort — never on a number spelled out of two names. Don’t take a low score to heart, and don’t treat a high one as a guarantee. Use it as a fun card to send someone for a laugh. The tool runs locally in your browser, and the names you type are never uploaded or stored.
10 Fun Facts about Name Matching
The most famous name-matching game is “FLAMES”: cross out the letters two names share, count what’s left around F-L-A-M-E-S (Friends/Lovers/Affection/Marriage/Enemies/Siblings), and whichever it lands on is your “fate”.
The “love calculator” was one of the internet’s earliest viral toys, all over personal websites and forum signatures as far back as the late 1990s.
Deterministic vs. random matters: if a test changes on every refresh it’s just a random number; only a stable result can ever be “compared”.
This tool sorts the two names alphabetically, so “you + them” and “them + you” always score the same — the match is symmetric, matching most people’s intuition about “us”.
Chinese tradition has its own name/birth-chart “matchmaking” (合婚) using zodiac, the five elements and stroke counts — culturally another form of “name matching”.
The psychological “Barnum effect” explains why such tests feel “kind of accurate”: vague, positive descriptions that almost anyone can see themselves in.
Splitting vague “love” into passion, friendship, trust and communication echoes relationship psychology: good relationships tend to balance several dimensions, not a single “love”.
These matching games spread because of social comparison: the number itself barely matters — sending it to someone and comparing with friends is the fun.
Amusingly, names change with nicknames, foreign names and renamings — so the same two people score differently depending on which name versions you use, a good reminder not to take it seriously.
This tool collects nothing: the names are used only in your browser, never uploaded or stored, and vanish on refresh.
Frequently Asked Questions
-
No, and it isn’t meant to be. It’s purely for fun — a fixed algorithm turning two names into a playful number. Whether a real relationship fits depends on time together, communication and effort, not a score from names. Enjoy it, don’t take it seriously.
-
Because it’s deterministic — by design. The tool maps names to scores with a fixed algorithm and no randomness. That’s what lets you compare: the same pair scores the same for anyone, reproducibly.
-
No. The tool sorts the two names alphabetically before computing, so “you + them” and “them + you” always give the same score. The match is symmetric.
-
Whatever you like — but note that different name versions give different scores (it’s computing on the characters). Use full names for the “official” run, or try nicknames and English names for a few more goes. It’s all for fun.
-
Each is a separate hash of the same pair with a different “salt”, so the four differ, and the overall is their average. It’s just to make the card richer and more fun — not a real psychological measurement, so don’t read professional meaning into it.
-
Of course. It just scores “two names”, so use it on best friends, siblings, idols, even pet names — all in the same spirit of fun.
-
Yes. Chinese, English or mixed all work — the tool computes on characters, so any text yields a stable score. The interface comes in Simplified, Traditional and English too.
-
No. The names are used only in your browser — never uploaded, written to the URL, or saved to localStorage. Refresh and they’re gone. RECATOOLS enforces zero-storage, zero-tracking.
-
Not at all. A low score is just a number from two names’ characters and has nothing to do with your real relationship. Plenty of happy couples score low, and vice versa. Take it with a smile.
-
Completely free, no signup, as many pairs as you like. It all runs in your browser, instantly.
