Landing page captured for the 2026-10-31 issue.

For: People laying out sports fields on available ground
Worth noticing: The page describes a 3-4-5 right-angle check and a diagonal check to help square a field layout.

Field notes

The page describes entering an area's dimensions or estimating a side by pacing, then checking which formats fit with run-off space included. Layouts can be rotated and combined, with up to 12 fields per site according to the page. For setup, it describes step-by-step measurements, cone counts, and paint estimates; the App Store listing is still marked as coming soon.
