Doorbell

How to use Doorbell:

Ring the bell, select a friend, and you're done!  It automatically sends them a message saying "I'm Here!"

Doorbell allows you to quickly let someone know that you have arrived.  Example: Say you are picking a friend up at their house.  Rather than call or try to write a text letting them know that you have arrived, just use Doorbell.  

A very simple time saving application free of charge.
