Expense Splitter
Financeweight 1tracker · keeps what you put in
Four friends, one cabin weekend, eleven receipts, and a group chat slowly turning into a courtroom. Expense Splitter keeps track of who paid for what and works the tangle down to who owes whom, so the trip is remembered for the trip. Fairness, it turns out, is mostly arithmetic done in front of everyone.
This is not a screenshot. It's the real tool, running right here — go on, put something in it.

Questions people ask
How does the Expense Splitter settle up a group trip?
You record who paid for what along the way, and the splitter untangles it into who owes whom. The maths is done in the open, which is what keeps it friendly.
Do my friends need to install anything or sign up?
No. There are no accounts at all — one person keeps the list in the one file, and the settling-up is read aloud or passed around. Considerably less friction than getting four people onto an app.
Where is the shared expense data stored?
Only in the browser of whoever holds the file. The splitter is a single offline HTML file — nothing is uploaded, nobody's spending is on a server, and the file is owned outright, forever.
