TaskPanel X

TaskPanel XTRA is an easy-to-use task manager that helps you manage your phone by conserving its memory and making it less laggy over extensive period of use.

You can kill or switch between running tasks and configure it to autokill when your phone enters sleep mode. In TaskPanel, all tasks are categorized into 4 main types - Normal, Ignore, Autokill and Service. If you are using Android 2.2 and above, tasks classified as 'Service' cannot be killed due to a restriction imposed by Google. You will be redirected to 'Settings' instead.

TaskPanel comes in 2 flavors of Widget - 4x1 and 1x1. The 4x1 widget displays a snapshot of your phone health status, available memory and enables you kill all running tasks with just a simple tap.

TaskPanel is designed top-down for personalization. You can also configure the frequency of update for the widget, enable Instant Access via status bar, specify the action to perform when a task is tapped, change theme and many more.

TaskPanel is extremely free. Hope you will like it :)
