Watchdog Pro is the first fully fledged backgrounding application for iOS 8. It allows applications run in the background based on the users needs. Features included are Smart Backgrounding, Prevent Suspension, and Keep in Foreground as well as Auto Launch and Prevent Termination. Smart Backgrounding forces select applications to freeze immediately when not in use allowing for improved battery life. Prevent termination allows applications with native backgrounding like SmartWatch+ to run forever in the background. Foregrounding allows applications that don't support backgrounding to run in the background like Twitch or your favorite games. With prevent termination enabled you can even allow applications to continue running when removed from the App Switcher. Full Activator support is also included but Activator is not required.
