Coinjot: Expense Tracker

Lost your expense history after a phone switch or a broken backup? Coinjot keeps every record on your phone, and one tap saves a backup file you control. No account, no login, no sync that can fail.

Coinjot is a simple expense tracker and money manager for people who gave up on budgeting apps because logging took too long.

LOG AN EXPENSE IN 3 SECONDS
• Tap +, type the amount, pick a category, save.
• The keypad is a calculator: type 12+6.5 and it saves $18.50. No more adding receipts in your head.
• "Copy last" repeats your usual coffee or bus fare in one tap.
• Home screen widget: see today's spending and add a record without opening the app.

KEEP YOUR DATA SAFE
• Save a backup file (JSON) and restore it on a new phone.
• Export CSV to open in Excel or Google Sheets.
• Deleted by mistake? Trash keeps records for 30 days.
• Works fully offline. Nothing leaves your phone.

SEE WHERE YOUR MONEY GOES
• Monthly summary: income, expenses and savings at a glance.
• Savings transfers are tracked apart from spending, so saving money never looks like spending it.
• Category donut chart and a 6-month spending bar chart.
• Calendar view with daily totals.
• Switch between month and week view.

BUDGET PLANNER
• Set a monthly budget and category budgets (food, cafe, shopping…).
• See how much is left and how much you can spend per day.

MADE FOR DAILY USE
• Expenses, income and transfers, with notes.
• Repeating records for rent, salary and subscriptions (monthly or weekly).
• Custom month start day — match it to your payday.
• Edit categories to fit your life.
• Your local currency, light and dark theme.
• Gentle daily reminder you can turn off.
