SeeYaSoon - for iPhone

Seeyasoon allows you to invite your contacts to your location wherever you are. Your guest will be provided with directions to drive to your location. Once your guest has arrived, you will be notified and can use the map to point your phone in their direction and find them. You can also use the app to invite them to a location on a map, or invite yourself to their location.
