Do you want to get free apps for iPod Touch? For an app to be a must-have for the iPod touch, it needs to hit one of the following criteria: It should work well online and offline, since Wi-Fi isn't as widely available as an always-on cell connection. It should be fun, since entertainment is the iPod touch's first job.
According to the criteria above, we select some free apps for iPod Touch to you. Next we will introduce these free apps for iPod Touch one by one.
Free Apps for iPod Touch: Skype

Skype app is the best free app for iPod Touch in the like product. Plenty of people are replacing desk and home phones with Skype, and the Skype app works perfectly on the iPod Touch. You can make and receive calls when you have an Internet connection (calls even run in the background, while you do other things), chat and send messages, and using a Skype number you can even talk to non-Skype users.
Free Apps for iPod Touch: Dropbox

There's a recurring theme among ideal iPod Touch apps—they're just as functional offline, as they are online. Dropbox, as a free app for iPod Touch, is a perfect example of that principle, giving you access to an always-up-to-date group of your files (2GB of storage comes free), and with a single tap just about any file you've got can be downloaded to your iPod, and viewed, played, or sent to someone. It's a necessity, and often a life-saver, whenever you're not near your computer.
Free Apps for iPod Touch: Evernote
This is possibly the richest and most useful productivity app for the iPod Touch. This free app lets you remember ideas, thoughts, events, special occasions and more. It lets you create and edit new notes on the fly, snap photos or record a quick voice memo.
Free Apps for iPod Touch: VLC
Video and music file support isn't an iPod strong suit—unless you have one of Apple's few supported formats, you're largely out of luck. Well, unless you install VLC, which will play almost any file type you can throw at it. You sync files via drag-and-drop in iTunes, and you can organize, play or delete them right from the iPod. If you want to bring a movie or a show on your iPod, but iTunes doesn't like the file, odds are good VLC still will. Unfortunately, the app's not available in the App Store for the moment (it was pulled in January), but keep an eye out for its return.
OK, that's all! Hope these free apps for iPod Touch can really help you. Enjoy yourself!
