PATANAVI is a green-reading app that lets you see the slope, distance, and aim point at a glance. With simple controls, PATANAVI analyzes the contours of the green in detail, using color to show elevation changes and arrows to clearly visualize the direction of the slope. It also measures the distance from the ball to the hole and uses the slope and distance to provide a suggested aim point. Green information that can be difficult to judge by eye can be viewed intuitively right on your smartphone. With the AI-AR Caddie button, you can also display a reference line to help guide your putting aim. See your usual green in greater detail.
