Questions
How does compatibility by date of birth work?
A date of birth gives your sun sign, life path number and Chinese zodiac animal straight away. Add a birth time and place and Intro works out your moon and rising signs too. Intro puts yours side by side with someone else's so you can see where you line up and where you differ.
Why does Intro ask for my birth time and place?
Your rising sign changes roughly every two hours and your moon sign every two to three days, so both need a birth time and place to be accurate. Without a birth time, Intro leaves your rising sign locked rather than guess.
What else can I add?
Four short quizzes: personality, love language, attachment style and colour theory. Intro compares every lens you and the other person have both completed.
Is Intro free?
Yes. There is nothing to pay for.
Does Intro use AI?
No. Every result comes from fixed rules, so the same birth details and answers always give the same result.
