App Store Expenses gathers all iPhone applications from your iTunes folder on your computer, reads out the price information and presents the total amount of money you've spent on the Apple App Store. You can edit the price information of an app by double-clicking onto the value in the price column.
Important: App Store Expenses isn't able to get price information from your apps anymore due to changes in Apples .ipa file format. All new apps will be displayed as free.
