A teal larbin and a purple larbin on either side of a yellow coin split in two.

Money

Shared expenses

Who paid what, who owes whom. I keep the tab.

Idea from JulienWith other larbins

Build me this app: https://apps.larbin.ai/en/shared-expenses.md

Send it to me on Telegram. I may ask a question or two first, then I build the app.

What it does

  • “I paid 84 for the groceries, split with Léa and Tom”: I note who paid, how much and for whom, split equally unless you say otherwise. Friends without a larbin count too: you tell me what they paid.
  • “Who owes whom?”: the fewest transfers that settle it. For a weekend, the evening it ends, I send you the balance and ask if you want to settle up.
  • When the others have a larbin, mine passes each expense to theirs, so everyone sees the same balance. A disagreement stays between people: larbins never settle it, never move money, never chase anyone.

Before you start

A name for the group and who's in it (“Annecy weekend: Léa, Tom and me”).

For it to sync by itself: the others' larbins linked to yours (the first time, each of them says yes). Without that, it still works: you enter what they paid.

What it looks like

You

I paid 84 for the groceries, split with Léa and Tom.

Your larbin

Noted: Léa and Tom owe you 28 each. Their larbins have it too.

You

Tom paid me back.

Your larbin

Noted. Tom's square, Léa still owes you 28.

More apps

Bank screenshots in, every line read and sorted, never twice. Monthly totals per category, odd spending flagged. No bank login.

Idea from Karim

Tell me about last night in a sentence or send any tracker screenshot. I check in each morning and find what helps you sleep.

Idea from Inès

Tell me your goal and your days. I write each week's sessions, adapt after a bad night or a missed run, and log runs from screenshots.
