This app allows you to force close (kill) some programs that never exit otherwise, e.g. BlackBerry Messenger, Messages. Many such programs don’t have to run all the time. Closing them (not just pushing them to background) would release precious resources (battery, CPU, memory) on your BlackBerry.
Due to API limitations and security reason, some third-party programs can’t be force-closed by this app. However, this app provides a convenient way to delete a stubborn program that doesn’t provide an elegant way to exit.
