AppMiner 2.0, by Bitrino, monitors the App Store for apps which have been discounted or become available for free. With a layout very similar to the App Store, you can easily view all newly released apps, all on sale apps and all top rated apps. Each of these options can viewed by sub-categories or you can view the top 100 in each section.

The most useful section is of course, the Sale section. Here, you can view the on sale apps in specific categories. My most viewed category is Top 100. Apps in each category are displayed chronologically which really helps to see all the newest apps that have just come on sale. Each category can be changed to display just the paid apps, just the free apps or all apps..

My favourite feature however, is the Watch list. Here you can add a watch for any apps that you would like to purchase but can’t afford or don’t want to pay the current price. You can select a target price and if/when the app becomes available at or below your target price, it will be highlighted next time you launch AppMiner. This makes it really easy to keep a tab on your potential purchases without having to go to the App Store and individually searching for the apps to check their current price.
