then you categorize expenses to get an understanding of your spending.

only after you have those categories, you can start to budget.

you can look at the categories and consider whether you are spending to much on a category or not.

if your cash flow is negative you need to find categories that you can reduce. likewise if you want to save money for future events.

i'd like an expense tracker that helps me categorize my expenses. your app seems useful only after i have done that.

the workflow i am looking for is:

i enter expenses as i make them, one line at a time. including breaking out groceries into individual items. then it should allow me to group items into categories. tracking which items don't have a group yet. finally it should tell me how much i am spending per group each month.
