TrackEcho

A GPS tracking and navigating tool which can be used for flying, cycling, boating, hiking etc.

Enables a user to define a trip, and email addresses of potential trip observer(s). The observers will receive an email with a link which enables them to follow the user on a server map.

The app user can also save and review historical trip summary data and breadcrumb trails on the device. The app can be used for navigating, direction finding, and saving location markers on the map.

Very useful if you want a friend to watch your trip progress (subject to you having at least partial cellular coverage) and perhaps take action on your behalf if you have not tapped the app STOP button after some time.

Can be used in general aviation by light aircraft pilots to send an informal "flight note".
