POCKETRANGER FREE GPS+tracking app for Iphone or Android

I know this is an app that is used for State Park travel but i used the Virginia and PA mobile app by POCKETRANGER as we were visitng colleges. Great GPS but the best was i used the Friend Finder feature to keep track of the whole family as we all went our separate ways. Was able to track my daughter as she drove across the state to visit a friend at another school. She even stopped at a senic overlook posted her waypoint and uploaded a great photo using the app! www.pocketranger.com
