The phrase identifies a category of mobile software applications designed for Apple iPhones that leverage global positioning system (GPS) technology. These applications assist golfers by providing course mapping, distance measurements, and potentially other features, all without requiring upfront payment for initial use. An example would be a program offering basic yardage to the front, center, and back of the green on thousands of courses, accessible immediately after download from the App Store.
Access to these tools can significantly enhance the golfing experience, particularly for casual or budget-conscious players. Historically, golfers relied on physical course maps or expensive handheld GPS devices. The advent of smartphone technology and the subsequent proliferation of such applications has democratized access to course information, leading to improved pace of play and potentially better scoring. Furthermore, the “free” aspect removes a significant barrier to entry, encouraging wider adoption.
