The 4.0 app update brings the Ball Tracer feature to the app. Whereas Shot Tracer tracks and traces ball flight during long shots, Ball Tracer makes your ball flight on short shots like pitch/chip shots, bunker shots visible. It does so by generating a strobe motion video sequence of the the actual ball flight. How to create a Ball Tracer: Select the Ball Tracer option in the Shot Tracer app (the icon with the many balls) Then simply select either the record a video or upload video option. Once a video is selected it will prompt you to set shot impact frame. The shot impact is auto set (if not set correctly, use the slider to set impact) Press save and video with the Ball Tracer is exported to iPhone video gallery.
