Back in the day, there was a jailbreak tweak called Backgrounder, which brought true app backgrounding to users before iOS even had native multitasking. That tweak no longer works for the latest firmware, but a new tweak called Watchdog aims to make true app backgrounding available today on iOS 8.
Watchdog is a beta tweak that's available via developer Allan Kerr's third-party repo. In this post, I'll show you how you can get Watchdog on your jailbroken device, and share a few use case scenarios.
