Today I am going to recommend to you the iPhone, iPad application: AppShopper. This little beauty of an application allows you to find any applications in the iTunes app store that are on sale for less than the original price or for free.
This is the perfect app for all you bargain hunters and those of you who never want to pay full price or any price (for that matter), for an application.
App shopper allows you to filter through hundreds of apps by choosing to find only the free apps, or by category, or by type, eg. new apps or price drops. You can even shop by popular apps that are on sale. There are so many different options and you can tailor it to your needs and wants.
So if you are looking to fill your device with some useful but inexpensive apps then I would advise you to download this one now!
