Google Latitude allows users to share their location with their friends using their mobiles. Powered by Google Maps, Latitude uses the same ‘My Location’ mechanism, so it will show your location to the nearest mile if it can’t get an accurate fix from the device’s GPS. This also means that Latitude should be able to be used on devices which don’t have in-built GPS, which lowers the barrier to entry for many potential users.
Users can also add an iGoogle widget, which gives the same ‘tracking’ ability directly from the iGoogle homepage.
Quite a while ago, Nokia created Friend View, a very similar application, but focusing on support Nokia devices. Google’s attempt covers a whole range of devices including S60, Android (of course) and will soon support iPhone, which is sure to raise the profile of the new service above Friend View.
