Mac: With iPhone apps so accessible and perfectly within impulse-buy pricing, it's easy to spend a ton of money without realising it. App Store Expense Monitor tallies up the price of all your apps so you know how much coin you've dropped.
This cool tool teases out all the apps stored in your iTunes folder, grabs their prices from the App Store, and gives you a complete overview of how much you've spent. It scopes out the iTunes folders of all the accounts on your systems, so you can even break down how much less you spent than your spouse (so you can catch up, of course).
The Expense Monitor uses the current price of apps in the iTunes store so there's no way for it to tell if you bought something on sale, or got it free before it became a premium app. Fortunately, you can easily edit prices in the Expense Monitor in just a couple of clicks.
Do you really want to know how much you've spent on apps since getting your iPhone or touch, or is ignorance bliss? Tell us in the comments.
