Responders

Do you need to know your friend's position and he still does not post you?
Responders on request match your location, height, speed, direction, accuracy, status. You can share the position directly with someone else.
Responders work with SMS. I do not require data.
Responders are compatable among themselves. It has a lot of features and advertising.
They work with Google, Mapy.com, UTM.
