Tasker from Google Play

Automating the work on a PC is not all that difficult, but the same cannot be said about the mobile platform. It’s not an easy task, but this is where Tasker comes into play. It’s a tool that is more than useful, as any users will quickly discover.
 
With the help of the application, it’s possible to use a particular App, Time, Day, Location, Hard/Soft State, Event, Shortcut, Widget, Timer, Plugins, and many other functions as triggers. More than 200 actions can be used as well, not to mention that you can use Tasker to make your own application.
 
Of course, as you can imagine, the application will need access to a variety of functions, but that’s to be expected.
