PuntoGPS
Minimalistic wide-open GPS-locator/tracker
PuntoGPS is a simple tracking application to show your position to others, e.g. during urban bike rides :)
It's made up of a GPS tracking app and a web based map.
The app can be run on any GPS equipped device (smartphone, tablet, etc) by the users that want to show their position and/or track their paths.
No user account is required, but users can set a short status message to identify (the default is the device name).
The web map shows the current position of the active users...
