One of the realities of having a
multitasking mobile OS in Android is
that you have to manage your apps so
that they don’t hurt performance or
battery life. Advanced Task Killer is
one of those apps you hope you don’t
need, but you sometimes must have. It
allows you to kill an application with a
single click. This particular app killer
includes an ignore list, a widget version,
and a long-press to menu feature.
