Tasker is a great app for Android.
What Is It ?
Tasker is an application for Android which
performs tasks (sets of actions) based on
contexts (application, time, date, location, event,
gesture) in user-defined profiles or in clickable or
timer home screen widgets.
This simple concept profoundly extends your
control of your Android device and it's
capabilities, without the need for 'root' or a
special home screen.
