There are a number of ways to find the best free iPod Apps for your iPod, no matter what version you own. The easiest way is to check out the “Top Free Apps” list on the Apple App Store homepage, or do a search for the type of free app you are looking for. Another great way to find free apps is to install the Free App Genie because it notifies you when paid apps are free or go on sale. That way you can get some of the most popular apps that are normally more expensive, for free or for a reduced cost.
The Free App Genie is a free app to download and free for thirty days after that, then there is a fee. However if you typically download a lot of apps and want to save money on some of them it could be well worth the cost. Or, you can use it for free for thirty days and then uninstall it.
