This System an iPhone App and Website which use a "Friend Access Password" to provide users' current location. Users' friends can use a link in an email or SMS message to access users' current location.

This system is simple, but useful, drivers can let friends estimate drivers' time of arrival and current location. Users can use this software to prevent the elderly or children lost their way. Hikers can let their family know their current position so that their family can report to the police immediately when accident is occurred.

For the professional version, it provides:
Manual GPS: You can manually send a location to your friend when GPS is not available.
Track Recorder: You can record the path for your journey.

Note: Continued use of GPS running in the background can dramatically decrease battery life!
