Habhub Tracker | http://habhub.org/mt/

Developer : Rossen Georgiev

The tracker webapp works both desktop and mobile devices. One key difference on mobile is the option for sending chase car telemetry. You will need to allow the webpage to access your position. Finally configure and enable the function from the top menu.

Issue can be reported on github.
