Its simple. It does a budget that rolls over weekly so it shows surpluses and deficits. It also allows adding to a budget incase you want to give yourself more money. Also it keeps a full history of weekly transactions and where you were regarding your funds (deficit or surplus). The budget is built easily. You give yourself a weekly allowance and it adds that much every period which is determined by you (weekly monthly daily etc)
