With Location Sender you can show your actual position just by one click to your friends. Every person who has permission can see this position by one click too.
The program sends the actual position (latitude, longitude, altitude and accuracy) to the web. This one can be shown online to other users or to another iPhone user and can be protected by a password.
Like all iPhone applications Location Sender cant run in the background and stops sending when you quit it.

Support for this app is very good. The developer is very helpful and responds quickly."
