My Jar: Budget Expense Tracker

My Jar is a budget and expense tracker that turns your money into something you can see. You put your budget in a jar: every time you spend, the jar empties. At a glance you know how much is left, with no spreadsheet and no complicated accounting.

Pick your currency and your period (day, week or month), log expenses in a few seconds and let My Jar work out your remaining budget, what you can spend per day and where you stand at this pace.

ADD AN EXPENSE IN SECONDS
Amount, category, note, date: that's it. Frequent amounts and notes are suggested, and an expense can repeat every period (rent, subscriptions…).

A BUDGET YOU CAN SEE
The jar visibly empties, your remaining budget updates, and income or a refund fills it back up. Over budget? No drama: the app tells you calmly.

HISTORY AND SEARCH
Expenses are grouped by day with the day's total. Search a note or category, filter expenses and income, swipe to delete (with undo).

CLEAR STATS
Spending by category, last 7 days, real pace versus ideal pace, comparison with the previous period, a spending calendar and category limits.

SAVINGS GOAL AND MOTIVATION
Set an amount to keep in the jar at the end of the period, follow your streak of periods on budget and unlock achievements.

EXPORT AND BACKUP
Export your expenses as CSV, back up and restore your data with a file you keep wherever you like.

ALSO
- 23 currencies, light or dark theme, choose your week start
- Optional daily reminder
- Available in English, French, Spanish and Chinese

YOUR PRIVACY
100% local: no account, no bank connection. Your budgets and expenses stay on your phone and you can erase everything at any time.

ADS AND PERMISSIONS
The app is free and shows a banner ad and, from time to time, a full-screen ad after you save an expense. You can manage your ad choices in settings. The notification permission is only used for the daily reminder, if you turn it on.

My Jar is a personal tracking tool: it does not give financial advice.
