Editorial interest 78/100 Selection signal · not a rating of the site

An iPad app for marking up PDF drawings, measuring to scale, and organizing review notes in layers and projects.

Landing page captured for the 2026-09-25 issue.

For: Architects and construction teams reviewing PDF drawings
Worth noticing: Scale is calibrated from a known dimension; the free tier allows unlimited PDF pages but limits projects and layers.

Field notes

After importing a PDF, users calibrate its scale against a known dimension, then trace two points to display a real-world measurement. Markups can be separated into layers, with visibility, opacity, naming, duplication, and locking controls; projects group PDFs by work. The free tier caps projects at three and layers at four per page, including the source PDF background, while leaving page count unlimited. The page says there is currently no cloud sync or collaborative editing.
