The most important aspect of putting is repeatable and consistent distance control. Distance control requires consistent tempo. Tempo is your putt timing comprised of the backswing and downswing. The TempoStik shows you how to putt with a series of LEDs that guide your putting stroke dynamics. The TempoStik App controls the TempoStik over a Bluetooth Low Energy (BTLE) link. Just set your personal Downswing Tempo and Backswing Rhythm ratio, then press Compute, and a perfect putting stroke is calculated by the TempoStik App. A built-in Putt Wizard calculates your backswing length based on tempo, green speed, up/down slope%, and the distance you want to roll the ball in feet. You’ll see the resulting backswing length in inches/cm. With the putting stroke computed, press Run/Stop, and you’ll see a perfect putting stroke indicated through the TempoStik’s LEDs. You’ll see the pre-shot sequence, backswing, downswing, and impact. Match your putting stroke with the moving LEDs and you’ll build consistent tempo and distance control. This app has been developed in collaboration with Visio Golf by Phil Kenyon, the World’s Leading Putting Instructor. Note: the TempoStik App requires a physical TempoStik putting trainer (available through Visio Golf) in order to function.
