GreenRead Pro

Putting is hard when you can’t see the slope.
GreenRead Pro is a professional green-reading app that uses the LiDAR sensor on iPhone Pro models to capture subtle undulations on the green. Slopes that are difficult to read by eye are visualized clearly with numbers and lines. Ideal for golfers who: * Often struggle to decide whether the putt breaks left or right * Want to understand distance and elevation change at the same time * Want to reduce 3-putts and lower their scores Key Features * Tap-to-measure: Place the ball and pin to instantly view distance (yd/m/cm), elevation change, break amount, and direction (H/S) * Putting trajectory line: Curved path visualization reflecting break, so you can picture roll more accurately * Aim line display: Red dotted line shows the launch direction at a glance * Slope direction arrows: Arrows indicate downhill direction around the line * Cross-section view: Visual diagram of elevation changes from ball to pin * Green speed support: Adjust trajectory for fast / normal / slow greens * Precision placement with zoom circle: Magnified touch placement support, plus left-handed mode LiDAR-compatible device required (iPhone 12 Pro / iPhone 12 Pro Max or later).
