Most step-by-step apps have a social networking feature that allows you to add friends through social networking and the two of you will compete against each other in a high scoreboard. But what if you do not have friends who have the same hobby as you? This is a free app with a unique social networking feature called TelFast. TelFast is a pedestrian team designed to encourage each other through chat groups and compete in the rankings. These are completely open groups.
