Spending dashboard

Where did the money go this month?

01 · The choreOnce a month your bank gives you a CSV. A hundred rows, and one question: where did the money go?

02 · The monthPut the file next to the app. Each row it knows falls into a category, and the bars show your month.

03 · The leftoversRows it can’t place wait as cards. Three this month.

04 · One clickClick a category. The row is filed, its bar grows, and the app saves a rule in rules.json.

05 · Next monthNext month, those shops sort themselves: fewer cards each time. The app has no internet, so your bank data stays on your computer.
