Come2Me

Let´s say you want to find the way to someone. This app makes it easy. If the other person has Come2Me it can within seconds send you his location. If you have this app open, it will recognize it and you can with a simple press be guided to the location or save it in your list (list is not available in free version)

An android phone is not necessary for this app to be useful. The app sends a text message that can be read from any other phone and gives a link that takes you to navigation.
