Shared money, made simple

Money is easier together.

Finbook is a shared expense tracker for families and friends. Track spending, split bills fairly and see who owes whom, without the awkward maths.

On the web today. iOS and Android apps are on the way.

Everything a shared budget needs

Simple enough for the whole household, careful enough for real money.

  • A space for every group

    A private space for you, plus family and friends groups. Everyone in a group sees the same numbers.

  • Split bills fairly

    Share an expense equally, by amount or by percent. Balances show who owes whom, to the cent.

  • Budgets and reports

    Set monthly limits for each category and see where the money went, with trends over time.

  • Private by default

    Amounts stay hidden until you choose to show them, and idle sessions sign out for you.
