This application allows a small number of iPhone owners to mutually detect their respective positions.
Registration is an essential preliminary step to use this application. Be aware that registration may only be completed if there is a network connection available (WiFi or 3G).
After registering with your mail address, you will get an unique numeric User Code, which will be shown on top of the main screen.
You may communicate your code to one or more different iPhone users.
By means of your code, these users will be enabled to discover your last position and view it on maps.
Exchanging user codes between two or more users will create a small group of persons, enabled to retrieve the position of each other.
When you receive the code of another user, you must insert it in your groups list. Only users registered in this list will be enabled to retrieve your location.
Be aware that a user is localizable only while this app is running on his iPhone,
and there is a network connection available (WiFi or 3G).
So, if you want to be localizable in a given time interval, launch the app, hit the Start button, and keep it running, even in background.
But be aware that continued use of GPS running in the background can dramatically decrease battery life.

Every 5 minutes the app will send a message to a server, containing your User Code, latitude, longitude, position accuracy and current time.
The server will record these data.
The other registered users of your group may request your last position, using your code as a search key.
When you prefer to stop transmitting your location, hit the Stop button, or just close this app.
