Is Drowser safe?

Avoid rogue apps from running in the background with Drowser. Drowser is a simple app that kills the selected apps when the screen turns off. It requires root and uses it to kill the apps with an 'am force-stop app-id'. This is a very impolite way of stopping apps. These might (and probably will) misbehave. You might also lose data because of this. Beware!
