Score (1–100): A fun, deterministic number generated from both names. The same two names always produce the same score, but it has no scientific basis.
90–100: The calculator labels this range "Soulmates" — the highest tier in its playful rating system.
50–89: Mid-range scores receive encouraging messages like "Very compatible" or "Good potential."
Below 50: Lower scores get lighthearted labels such as "Opposites attract?" — remember, it is purely for fun.
How This Calculator Works
You enter two names. The tool lowercases and concatenates them, then runs a simple hash function (a bitwise shift-and-add loop) over the combined string. The resulting integer is reduced to a 1–100 range using modulo arithmetic. Because the hash is deterministic, the same pair of names always yields the same score. The algorithm has no relationship to actual compatibility.
Quick Questions
Is this scientifically valid?
No. The love calculator is a novelty tool. It uses a math hash — not psychology, astrology, or any validated compatibility model. Treat the result as entertainment only.
Why do I get the same score every time?
The hash function is deterministic — the same input always produces the same output. Swap the order of the names and you may get a different score, since the concatenated string changes.
Does capitalization matter?
No. Both names are converted to lowercase before hashing, so "Alice" and "alice" produce the same result.
Can I use nicknames or full names?
You can enter anything — first names, full names, nicknames, or even pet names. Different strings produce different scores, so "Bob" and "Robert" will give different results.
