Launch Code Tempo Training is an iPhone app developed by Speed Ring Golf LLC, available for free in the Lifestyle category under Sports subcategory. The app focuses on tempo training as a key technique to enhance golf performance. It is based on the discovery that the best golfers share a specific mathematical ratio in their swing tempo, 3 to 1, measured over an elapsed time where 30 frames equal one second.

The app features a series of notes played in the 3 to 1 ratio, catering to various swing speeds. Users can practice with different note patterns corresponding to common swing tempos, ranging from slower to faster speeds. This allows golfers to find and master the ideal tempo for their swing, aligning with the techniques employed by top golfers worldwide.
