About
MEASURE IT WHERE IT STANDS.
Plumb Tape turns your iPhone into a camera tape measure. Point it at what you need sized up, tap a start point, drag to the end, and read the real-world distance right on screen. No fumbling with a reel, no second set of hands, no writing numbers on a scrap of drywall.
Built on Apple's ARKit — and using the LiDAR scanner for extra depth accuracy on the iPhones and iPads that have it — Plumb Tape locks its endpoints to the world so the reading holds steady while you move the phone to check it.
BUILT FOR THE JOB, NOT THE LAB
• Level-aware snapping catches clean edges and corners, and locks the run dead horizontal or vertical when you want a straight pull.
• A zoom loupe pops up as you place each point, so you drop it exactly on the corner instead of near it.
• A haptic ratchet ticks off the length as you drag — you feel the measurement, not just read it.
• Read in feet-and-inches or metric, rounded to the fraction you work in — from 1/2" all the way to exact.
• Big, high-contrast controls and thick borders built for the field and bright sun.
SAVE THE PROOF
Tap Save and Plumb Tape stores the measurement together with a photo of the scene — with the tape drawn right on it. Everything lands in your Saved ledger: searchable, pinnable, and time-stamped, with an optional jobsite location stamp, a title, and notes.
SHARE A CLEAN RECORD
Export your saved measurements as a PDF or PNG ledger, or back the whole set up to a .plumb file. Turn on Export Branding to stamp your own business name, contact info, and logo on every export — a tidy paper trail for the client, the GC, or your own records.
WORKS WITH ZERO BARS
Everything runs on the device. No account, no login, no cloud, no network needed — measure in a basement, a bare shell, or the middle of nowhere.
WHO IT'S FOR
Carpenters, remodelers, framers, drywallers, painters, electricians, plumbers, inspectors, movers, and DIYers — anyone who needs a fast, close-enough dimension and a record of it.
ENGLISH & SPANISH
The whole app, including your exports, in English or Spanish.
PRIVATE BY DESIGN
Plumb Tape collects nothing. No tracking, no ads, no analytics, no third-party SDKs. Your measurements and photos never leave the phone unless you send them yourself with the iOS share sheet.
ONE PRICE, THAT'S IT
A one-time purchase unlocks the whole app. No subscriptions, no in-app purchases, no paywalls, ever.
A note on accuracy: AR measurements are fast estimates for planning and reference. For cuts, code, or anything safety-critical, confirm with a physical tape or laser.
