Sharing your location with your friends has never been this easy! And its free!*
No registration. No credit cards. No hassle!
To share your location you need a mobile phone with an internal or an external GPS, and a network connection.
The only thing your friend needs to know, or do, is to open the link you sent with SMS, which they can use to track you on any PC or Mobile phone with a web browser.
Puskaradio is so easy, even my mother knows how to use it!
