I recently received an email from the SCGA advising that those functions are going to be added to the GHIN app in Mid late July. Including a GPS function for courses too! For a premium, they will include all kinds of stuff to the basic app of layout/green and center of green distance. It will definitely slow play even more than it already is with the other apps, etc. I support not allowing the green reading apps. I do not want to be out in the SC heat for longer than necessary. Pace of play has always been issue in the years I have been attending.
