just add the widget and each click will send predefined text message to specific number of your choice
e.g. click the green button to alert your boss you started your work day
and click the red button to alert him you finished for today and also if you want the message can be sent to someone at home waiting for you to finish working, so they can start cooking...
you are in a first date? predefine the buttons, one will alert your friend all is going well and if not so just click
the second button and tell them to "rescue" you with an "emergency" call, and the date will not suspect cause you just clicking a widget and not starting to write a message....
and many more... just a click away
