I'm planning on sharing a trip with my cousin. I know he has an Apple but not sure which app he uses but before I suggest the idea, knowing that he is fearful of technology, I don't want to suggest my plan until I know which app he has and if he is using it. It may be that I will share just my half of the trip so he will have an idea of where I am during the trip. If he doesn't use any mapping app, will he be able to follow our progress? Any ideas?
