Find out how much you’ve spent at the iPhone App Store

Appropriately named App Store Expense Monitor does exactly what it’s name implies, it tallies up your App Store spending on iPhone/iPod Touch apps and gives you a grand total. The app works by reading your iPhone App information from the iTunes folder on your Mac and then it just tallies up the prices, but it does allow you to edit price information in case you got an app for free or at a reduced cost.
All of those little $0.99 purchases can sure add up!
