SimpleBudget is a very easy-to-use application for keeping track of where you spend your money. You enter deposits and payments in a checkbook-style list, setting the expense type of each from a popup menu. The Summary screen lets you see the totals for all expense types over any desired time period (week, month, year, etc.) Any expense type can have any number of sub-types (and the sub-types can have their own sub-types, etc.). This lets you track, for example, your overall automobile expenses, as well as the more specific fuel, repair, and loan payment expenses.
