This is a nice little App, particularly for parents.  Instead of paying AT&T for their Family Map plan, you can get this free App, to install on your Android, iPhone, or even your iPad.  You can specifuy the interval for when the updates are made, but using GPS it registers your current location to a webservice, where another phone, iPad, or Web Browser can view, and see the lcoation.

This is the perfect tool, for parents wanting to keep track of where their children are located.  It is has many other features which make it that much better of an app to have to and to use.
