Doc's Putting Trainer is an Apple Watch Only App that assists golfers in determining their best putting stroke temperature, starting the backswing to impact, and training to minimize the putter face rotation rate during the stroke. DPT is a live, real-time feedback trainer that allows golfers to practice putting anywhere. Golfers can personalize their tempo and adjust how much of an acceptable putter face rotation is during their stroke. Not all golfers will be the same. To reduce three-putting, develop your perfect tempo for all distances on the putting green.
