The best and most solid task killer I've used. The battery life on the HTC Incredible is a know weakness. Advanced Task Killer will definitely get your Droid through the day by auto killing all the apps that keep running in the background. Won't slow your Droid down and the UI is simple and intuitive. ATK has a plethora of options to set how "aggressive" the killer will be so you can choose to which apps you want to keep running. Or stop those annoying app start-ups before they completely drain your precious Droid of its life-blood so you can focus on more important things like playing Metriod on you NES emulator or downloading more goodies from phandriodcom. Whether you choose to have it auto kill or if you prefer to manually kill apps, ATK is an app no Droid can live without.
