Download the android app and log in. Then send your friends a link with a map showing your live location.
Your location updates every second for all the world to see.
It's free, but you can donate if you want to help with server expenses.
You can track your GPS location from your phone's web browsers. There's also has an android app which can run in the background. With the app, you can:
If you need to go undercover, just turn tracman off with the flip of a switch.
Change your settings to show a less accurate location, if you want an air of mystery.
If nobody's tracking you, tracman won't needlessly drain your battery.
You'll get a simple webpage with a map to send to friends. It'll look like this.
Just send a link to whomever you want. Bam, now they know where you are.
Map updates in realtime with websockets.
Change the map default type and zoom level. You can also show speed, altitude, and streetview.
This is beta software, so there are still kinks to be worked out.
Also keep in mind that publishing your location online could be a bad idea.
I assume no responsibilities.
You will need a google account to join tracman and log in.
