Stop flipping.
Start asking.
Roughin is a blueprint reader built for jobsite phones — sorts every sheet, answers your questions, and shows you the exact page the answer’s on.
Reading plans on a phone shouldn’t be this hard.
50-page PDFs
Drawing sets are designed for desks. You’re standing in a half-framed wall.
Pinch-and-pray
Sheet thumbnails are too small to read. You zoom in and forget where you were.
“Where’s that detail?”
Every detail callout points somewhere. You scroll until you find it. Or you don’t.
Upload the set. Ask the questions. Get answers.
