Everyone loves a bargain, especially if it's a great app that you might have considered buying... but deals in the Google Play store aren't exactly easy to track down. Enter AppSales.
The idea behind AppSales is simple - it shows you all the apps that are currently available at a reduced price with information about the app and a direct link to the Google Play store.
Where AppSales excels is not only in the accuracy of it's data (which is excellent), but also in the polish of it's UI and the configurability of it's notifications. The application makes great use of ActionBarSherlock and HoloAnywhere to provide a very modern, ICS style UI even on older devices. The minimum discount level can be set anywhere from 25% and the app can automatically search for new deals from every hour up to every 24 hours (or not at all).
Best of all, AppSales itself is a free download from the Google Play store. What's not to like? Visit the product page to download your copy!
