When most apps in the iTunes store cost from $0.99 to $2.99, you don’t really think twice about purchasing a few apps every now and then. But when you actually watch the figures accumulate, you could be surprised to see just how much money you’re spending.

But, there are certain legitimate ways to get your hands on some paid iPhone apps for free. None of these methods require that you jailbreak your phone – but some of them do require a little bit of patience.

Free App Alert

FreeAppAlert is a great website that you can visit on a daily basis, or better yet, receive a daily email listing all the newly free iPhone apps for that day. The email contains links to view the app on the FreeAppAlert website, or on iTunes. Each app listing is accompanied by the information you would read about the app on iTunes.

AppMiner

If you’re on the go and would prefer a convenient way to keep up with price changes in the app store, AppMiner [iTunes link] is a great way to do just that. You can browse apps by category, or by the top rated apps.

AppShopper

AppShopper lists all the changes in prices in the app store, including those that have gone from paid to free iPhone apps. You can narrow your results by iPhone/iPad apps and by categories.
