Budget tracker app for iPhone?

[fatsatsuma]

Does anyone use one of these? Can you recommend one?

I'm looking for an app where you enter, say, your food budget for the month, and then enter each shop you make, and it tells you the running total etc.

I know you can do this with a piece of paper and a calculator, but an app would make it more fun

I use ixpenseit, i think it could be adapted for this. There is a lite version you can trial
