Leftover is a simple budget tracker and expense tracker that answers the one question that matters: how much money will you actually have left before payday?

Add your income, your bills and your everyday spending. Leftover works out what's already gone, what's still due this month, and what's left over — so you can plan your budget without spreadsheets, without linking a bank account and without creating an account.

SEE WHERE YOUR MONEY GOES
One colour-coded bar shows your whole monthly budget at a glance: rent, groceries, transport, debt, savings and everything else, with what's left over at the end. A ranked breakdown shows which spending categories take the biggest share of your income.

RECURRING PAYMENTS AND BILLS THAT TRACK THEMSELVES
Set up rent, subscriptions, loan payments or your salary once — weekly, every two weeks, monthly, quarterly or yearly — with the exact date and time. When a payment falls due, Leftover records it and your balance updates. Haven't opened the app in a while? It catches up on everything the moment you do.

QUICK EXPENSE TRACKING
Spent money on coffee or groceries? Add the expense in seconds — it's dated now by default. One-off income such as a bonus or refund works the same way.

BUILT AROUND YOUR PAYDAY
Paid on the 10th or the 25th instead of the 1st? Leftover follows your pay cycle, so your monthly budget runs from payday to payday and shows exactly what has to last until the next one.

MULTI-CURRENCY AND TRAVEL SPENDING
Paying abroad? Enter an expense in its original currency and Leftover converts it at the mid-market exchange rate — the rate you see when you search online. Add your bank's foreign transaction fee and the converted amount matches what your card actually charged. 24 currencies, and rates are saved so it keeps working offline.

YOUR OWN CATEGORIES
Start with eight spending categories, then rename, recolour, delete or create your own directly from the expense form.

SAVINGS WALLET
Money you move into savings is collected in its own wallet, with a running total and a full history of every deposit.

FULL TRANSACTION HISTORY
Every payment is listed by day, with upcoming bills shown first. Made a mistake? Undo any transaction with one tap and your balance corrects itself.

MONTH-BY-MONTH COMPARISON
Past months build themselves from what you actually spent, so you can see whether you're spending more or less than last month.

PRIVATE BY DESIGN
No account. No sign-up. No bank login. No ads. No tracking. Your budget and financial data stay on your phone and are never uploaded — we couldn't see them even if we wanted to. Works fully offline, and you can export a backup file at any time.

15 LANGUAGES
English, Serbian, Swedish, German, Dutch, Italian, Spanish, French, Portuguese, Polish, Turkish, Russian, Chinese, Japanese and Korean.

FREE, WITH AN OPTIONAL DARK THEME
Every budgeting and expense tracking feature is free. If you'd like to support the app, a one-time purchase unlocks a dark theme. Nothing else is behind it.
