Apple’s Find My Friends app which was  introduced together with iOS 5 a week ago  is here in the App Store, even though you’ll require the latest version of the software to be able to in fact install it. The actual free app, which in turn utilizes GPS to find your friends and family as well as, if your ownprivacy configurations mash properly, exhibit all of them on the map within real-time, are available here .

Like Google Latitude does on Android, Find My Friends will allow iPhone, iPod touch and iPad users to see their friends’ locations. Access to your position can be granted permanently, or groups set up to reveal location for a specific length of time: for instance, until the end of a day out to the beach or a theme park.

There’s also a single switch that turns off all location sharing, for those times you want to be completely off the grid.
