You can add one or several widgets that come up as buttons labeled with NAME and MESSAGE on your home screen. When you click on the button the widget immediatly sends the MESSAGE to your loved one.
Please use sparingly if you don't have a all inclusive text/SMS plan.
It is destined for all those of us who often think of their loved ones and never quite get round to texting them our thoughts. Quite honestly this has been a real great addition to our family life.
