An app lets construction workers open Jw_cad .jww drawings on an iPhone, iPad, or Android device, measure between two points, annotate the drawing, and save it in JWW.

Landing page captured for the 2026-08-25 issue.

Field notes

The app is designed around a recurring site-work sequence: receive a Jw_cad drawing, open it on a phone or tablet, select two points, read the dimension, annotate, and send the file back. The page lists JWW and PDF for viewing, and JWW, PDF, and DXF for saving or export. Its measurement aid snaps toward endpoints and intersections, while the instructions explicitly address the problem of a finger obscuring the drawing.
