The Golf SwingShot Tracer app is a simple way to trace your golf swing. It uses your phone's built-in camera to capture and store the motion of your swing, then plays it back to you, allowing you to see the path of your swing in slow motion.
To use the app, simply open it up and select the video you want to trace. You can also adjust the settings like the number of frames to trace and the depth of the frames.
Once you're ready, click the [Play] button to start the video. When the video is finished, you can click the [Stop] button to end the video.
