A free expense tracker that does the arithmetic exactly

Logging an expense takes one line

The quick-add box parses a whole transaction from plain text, so the common case never opens a form. Type the amount, a title, an account and a category and press enter.

• `12.50 coffee @cash #food`: an expense of 12.50 from Cash, categorised Food
• `+2400 salary @bank`: income, because of the leading plus
• `(45+18)/2 dinner @card`: the amount field is a calculator, so splitting a bill needs no mental arithmetic

Every amount is an exact decimal

Money is stored as NUMERIC(19,4) in Postgres and handled with big.js in the browser. There is no floating-point arithmetic anywhere in the money path, which is why a long list of small transactions still adds up to the number you would get on paper.

The history is grouped the way you think about it

Transactions are grouped by day with income and expense totals per day, and the whole ledger is virtualized, so ten thousand rows scroll at the speed of ten. Filters for type, account, category, amount range, keywords and tags all live in the URL, so a view you built is a link you can send.

A dropped connection does not stop you

Chillar's needs the internet to sign in and to sync, but not to keep working once it is open. It installs as a progressive web app, pages you have visited render from cache when the network is gone, and a transaction you log with no signal waits in the browser until you reconnect. Each one carries a client-generated id, so a retry can never double it.
