Apple's current Find My Friends feature could one day expand into more of a Track My Friends feature.

Granted to Apple on Tuesday by the US Patent and Trademark Office, a patent called "Sharing location information among devices" describes a process that would let you view a visual representation of the path taken by another person using a mobile device as a way of following that person's entire journey.

For example, someone is going for a hike or a trip and wants you to stay informed of his or her whereabouts. That person would enable a feature on a mobile device to allow you to see and track in real time the path being taken on your own mobile device or computer. On the flip side, you could also share your route so the two of you can stay abreast of each other's ongoing location.
