Trail Treker takes any map and makes it work with your GPS-enabled smartphone...offline. Trail Treker works with clubs, resorts, and municipalities to bring their local map(s) into the 21st century by placing that map on the smartphone of all users/visitors. This allows the user to know exactly where they are at all times via GPS (without mobile phone coverage!). Trail Treker also allows the subscribers to upload a list of businesses or points of interest to show on the map driving more traffic to those places--now the clubs have a chance to give back and enhance the safety of all users!
