I don't understand how to track where my friend was , if i invited them they'll know that I was tracking them right? I don't think so it may helpful to all u should make some changes as per our perception.........nd it's bit confusing too ..make sure to solve those problems facing by ur customers and let v know the best moves by uh .. looking forward use this app as soon as possible after the modification....let us know how to track friends address like where they're without knowing them . tq...
