Puttalyze

Puttalyze-App simulates the path of a rolling golf ball on a green to help golfers improve their "reading the green" skills by visualizing the concepts of "aim point", "distance point", and "target speed". After entering all relevant parameters, the resulting trajectory is calculated and displayed graphically. The "distance point" and "aim point" are shown, along with the relevant distances, on a result screen. This helps golfers understand the physics of a rolling ball on an inclined surface intuitively and teaches them how to aim and adjust their shots based on the slope and other properties of the green, such as green speed.
