How it works
Three steps.
No endless questionnaires.
Enter your date of birth
Cosmatch uses it to calculate your numerological archetype — one of twelve. You see your archetype’s name, its traits, and how you love.
You see profiles, not just cards
Instead of endless swiping, you get five profiles a day for free, ranked by real compatibility. Every profile tells you why this particular person fits you according to your dates of birth.
You meet in the real world
Match → message → coffee. Disconnect as fast as you can and get back to real life.
Five relationship categories
Every person writes
a different story with you.
Cosmatch calculates what your relationship could look like before you even exchange your first message.
Soul Mates
A deep, calm connection. Natural harmony without effort. A rare and highly prized bond.
Love & Friendship
Mutual support, shared values, ease. A very favourable combination for a long-term relationship.
Fatal Attraction
Intense magnetic pull. Passion that can’t be controlled. Can be as enchanting as it is destructive.
Beneficial Bond
A complementary partnership — the other person brings you something you lack. It fuels growth.
Challenging Bond
A relationship full of tension and transformation. It teaches you things you wouldn’t learn anywhere else.
What Cosmatch doesn’t do
It won’t flood you with profiles.

When a message arrives, a real person actually wrote to you.
