GST is the world's largest and most popular golf swing analysis app.

GST provides golfers with all the data they need to improve their swing.

Data is collected from a golf swing analyzer, and sent to a server where it is saved and made available to the user.

The app displays the data on a graph, allowing the user to compare different periods of their swing, and see the differences.

It is also possible to use the data to create a personalized lesson, and send it to the user's instructor.

The instructor can then use the data to create a personalized plan, and send it to the user.
