Chronos

Chronos provides you with functionality to control the multitasking behaviour of your device. Including:

Fast Freeze - Instantly freeze apps that enter background, so they cannot continue their background processing - but are not entirely killed.
Foreground - Apps that are sent to background remain in a foreground state, even when the device is locked.
Kill on close - Immediately kills the app when it enters the background
Relaunch on exit - When an application exits, it will instantly be relaunched

Note: You will be able to download a package without purchasing. However, the package must be activated from the settings pane after purchase.
