budget. I don't want one where we have to enter our expenses manually because that fails all the time. What I'm looking for is an app that allows me to enter how much money we want to spend on a monthly basis, that pulls in data every time we spend electronically, and gives us a running number of how much we have left for the month.

Basically, it would need to mimic a cash budget. I don't really care about detailed assignments of money because financial requirements tend to change from month to month.
