Love Calculator

1. Type your name in the first field. Use your first name, full name, or nickname.
2. Type your partner's name in the second field.
3. Click "Calculate Love Score" to reveal your compatibility percentage and rating tier.
4. Read your description below the score ring. Each tier has a unique message explaining what the score means.
5. Try different name variations to see how nicknames vs. full names change your score. Some couples swear by their initials!

This calculator is for entertainment only. Compatibility in real relationships comes from communication, shared values, and mutual respect, not a name-based algorithm.

The love calculator uses a deterministic hashing algorithm applied to both names combined. Here is what happens under the hood:

1. Both names are joined together and converted to lowercase.
2. A polynomial hash (multiply by 31 and XOR each character code) produces a large number from the combined string.
3. A second value mixes in the letter counts from each name individually, weighted by prime multipliers (7, 13, 17) to add name-length sensitivity.
4. The two values are XOR'd together and mapped to a 0-100 range.

The result is deterministic: the same two names always produce the same score. The algorithm is symmetric, so "Alex + Jordan" and "Jordan + Alex" give different scores, just like in real life where perspective matters.
