AT&T is unveiling a new app that will allow parents to track their children's location from their iPhone.

The app, called FamilyMap, will give parents the ability to bring up a map on their iPhones that pinpoints the location of their children. The subscription service was once only available on the PC.

More than 60 percent of AT&T wireless customers are part of a family plan or multiple line account, so there's a considerable number of our subscribers whom we believe will find this service beneficial, said Mark Collins, vice president of Voice and Data Products at AT&T when launching the service last year.

Users can locate up to two phones on an account for a monthly subscription of $9.99, or up to five phones for $14.99 per month. This pricing is consistent across all AT&T's wireless portfolio.

FamilyMap is powered by LBS provider Wavemarket
