Shared money, split fairly.

Kin is a money app we're building for couples, polycules and roommates. It splits shared costs by what each person can afford, so nobody quietly carries more than their share.

Who's in your kin?

Every household shares money differently. Kin works the way yours does.

One shared pot

Each of you puts in your fair share, and shared spending comes out of the pot. No tallying who bought the milk.

Pots that overlap

Rent between three, groceries between two, a trip between four. Each cost goes to the people it belongs to.

Bills, sorted

Rent, utilities and the group grocery run, split your way, with one simple "who owes whom" at the end of the month.

Fair by default

Set a fair-share ratio once, by income or whatever you agree on, and every shared cost follows it.

Made for more than two

Couples, polycules and shared houses, each with their own split.

You choose what's shared

Share only the spending that's shared. Your personal purchases stay out of view.
