Editorial interest 84/100 Selection signal · not a rating of the site

A planned iPhone LiDAR app scans a putt, maps the green’s slope in 3D, and calculates an aim line and speed for the shot.

Landing page captured for the 2026-09-11 issue.

Field notes

The described workflow combines a 45–75 second walk from ball to cup with LiDAR depth capture, surface gridding, and rolling-ball simulation. The page reports 15 depth frames per second, 1.5 cm grid cells, and approximately 1 mm height noise after fusion. Its browser demonstration exposes the same style of speed-dependent aim calculation, while the phone experience is described as requiring an iPhone Pro with LiDAR on iOS 18. Course lookup is tied to a stated Dutch database of 3,511 greens.
