BlackBerry World is constantly growing, but as with any app store, it's difficult to keep track of new apps.
On occasion, paid apps become free or are offered at discounts. This free app tracks such deals. The app integrates with the BlackBerry interface and displays a notification in the BlackBerry Hub whenever a new deal is found. You can view featured apps, newly free apps or apps with price drops.
Discounted apps are shown in a list (sorted by date) along with the revision in price. Currently, the app only displays prices in USD. Tap on the app name and it will automatically direct you to BlackBerry World to download the app. While the free version does not limit any functionality, it is ad supported.
