Never misread a putt again. PuttView shows you exactly why you're missing. The average amateur golfer takes 40 putts per round, while PGA Tour players only take 29. This 11-stroke gap is the most recoverable gap in golf - and PuttView helps you close that efficiently. Instead of just rolling putts, start practice deliberately with immediate and accurate feedback on every putt. Using your iPhone's LiDAR sensor, PuttView scans any green and overlays precise, data-based visuals directly on the surface. Contour lines, slope arrows, the correct putting line, aiming point, and speed and distance data. All in real time. On any real green, indoors or outdoors. No guesswork. No estimation. Just the read. What PuttView shows you: Contour Lines See the exact topography of the green. Scan any surface, with or without a putt lined up. Understand how it breaks before you ever address the ball.

Ideal Line: Not just the optimal line. The correct line, calculated for perfect pace.

Aiming Line & Aiming Point: A precisely defined start direction and target point. Eliminate alignment guesswork entirely. Putt Info: Speed, distance, and break data for every putt. Build a feel for pace and line grounded in real numbers. Built for golfers who take their game seriously. The PuttView app is not a simulator. It works on any green, outdoors, and indoors.
