Know what's left.
A lightweight budget tracker for a paycheck, a period, or a purpose — groceries, a trip, monthly spending, anything with a limited amount. Set an amount, add expenses, and always know what you have left.
One number, not a dashboard
What's left is the only headline. No charts, no categories fighting for attention — open the app, read one number, close it.
Log an expense in seconds
A purpose-built keypad with arithmetic where you need it: type 3 × 120 for three nights and let the app do the math.
Spend in any currency
Declare the currencies a budget uses and the rate you got. Entries convert to your home currency, so the one number stays honest abroad.
Finish it when you're done
When a budget period or purpose is finished, move it to the archive. Your active pockets stay focused without losing your past spending records.
Private by design
No account, no sign-up, no tracking. Your budgets live on your device. Read the privacy policy — it's short because there's little to explain.
Free to use. Pro if you need more.
One Pocket is free with two active budgets. Pro unlocks unlimited budgets for a one-time purchase — no subscription, because a budgeting app that charges you monthly is a bill.
