How it works
******************

1) Mark your alert point on the map with a corresponding notification point nearby.
2) Associate a receiver (sms number and sms body or mail address, subject and mail body)
3) Starts the app and set it in background.

If the alert point is an "email" alert point:
When the iPhone is nearby the alert point automatically and in silent mode the device send a mail to mail address also with a maps link where you are.

If the alert point is an "SMS" alert point:
A notification appears in your iphone playing also a ringing sound. You have to open notification and a precompiled sms is shown in your iphone with the data you setup before. You have only to touch the send button!

If you choose a background sms alert point the sms is sent without user confirmation completely in background, but you have to make an account with sms provider and buy a little sms credit.

It can be useful to let known when you'll arrive, All without you fiddling with your phone at 55 mph.

Some case of use
*************
Tim is go by car to girlfriend home, before start setup the app so that when he will be near destination the girlfriend automatically receive a mail like this:

Hello Baby, go down I'll be there in 5 minutes!

A professional use can be for checking a delivery man.
The boss set some alert point corresponding to delivery address, and give an iphone to the delivery man.
When he arrive in each of alert point the boss receive a mail with a customized text and location link (he can open it in a web browser).

Continued use of GPS running in the background can dramatically decrease battery life.
