I am a Sailor app for iPhone and iPad

This app will send a SMS to the contact person to tell that the sailor is going out and when the sailor
expect to be back. When the sailor is safely back on shore the sailor press the “back on shore button” so a
SMS is sent to the contact.
In case the sailor has not returned or do not push the “back on shore” buttom the telephone will sound an
alarm and a SMS will be sent to the contact with last know GPS position. A server is at the same time
surveying the activity, so in case the sailor’s telephone is not in reach or run out of battery, the server will
send the SMS and inform the contact about the situation.
