I have been using this app since the day Greg Norman invested in the company. Not once, even with each update, has it ever automatically tracked my ball flight. Your video must be perfectly backlit or something for this feature to work? The past two attempts at using this app, it picks up the start line behind my body (not even close the ball) and there is no way to reposition where the start point is. Each time I have a video I am excited to edit and share, I come away disappointed. Have not tried the GPS/Map Overlay free trial. Can only imagine I would hold up the groups behind me trying to record and post a shot?! UPDATED APP 12/11/17 Another App update, another app FAIL. The auto trace feature is a joke... sends ball behind me. I use a tripod. I set up phone EXACTLY where I was taught. This never works for me. I have made ONE successful Shot Tracer App and it took me 20 min to manual trace. NOT WORTH THE MONEY. I am so disappointed.
