I love this app. Its super accurate, and I once tested it, crossing a street multiple times and making designs-does a spectacular job of tracking your route. It also tracks speed and motion, and if it seems like youre going faster than usual/nervous, it will ask you to confirm you are okay or else it will contact your companion. This app has made my boyfriend and I feel much more secure when I travel alone at night and I feel its necessary for anyone who walks alone to be safer.
