iPhone
Type "-25 lunch" and you're done. No account, no bank login, no ads: your entries stay on your iPhone. The simplest way to see where your money goes.
Track your money in one line. Type "-25 lunch" or "+500 freelance" and it's saved. No categories, no account, no bank connection, no ads.
OneLine Budget is a minimal expense tracker for people who gave up on complicated budget apps. Open it, type one line, close it. That's the whole habit.
WRITE IT LIKE A NOTE

OneLine Budget reads the amount and the sign, saves the entry and keeps income and expenses apart for you.

New Currencies and More Reliable Exports
This update adds four currencies, makes your exports more dependable and prepares OneLine Budget for upcoming features.
• More currencies: Australian, Canadian and New Zealand dollars and the Swiss franc are now in the currency list. Each dollar shows its own symbol (A$, CA$, NZ$), so you always know which one you're looking at.
• Smarter CSV Exports (Plus): Notes with quotation marks or line breaks no longer break your file, and dates in English exports now stay in their own column. Your exports open cleanly in Excel, Numbers and Google Sheets.
• Ready for what's next: On first launch, your entries, recurring items and settings are carried over automatically to a new storage location. Nothing is deleted.
• General performance and stability improvements.
