Plumb Level: Spirit Level

About

Spirit level and bubble level for your phone: a digital inclinometer for level, plumb and 45° angles. Plumb Level turns your phone into a precise digital spirit level — no glass vial to squint at, no batteries to buy. Lay it on an edge, stand it against a stud, or hold it to a pipe, and read the angle to a tenth of a degree. FOUR WAYS TO READ • Linear tube — targets level, plumb, or 45°; or set Auto and it tracks whichever the phone is nearest and turns the vial to match. • Bullseye — a surface vial that shows the high side of any flat plane at a glance. • Plumb bob — a true hanging plumb for checking verticals. • Torpedo — a go/no-go mode: set a target angle, then tilt to match, with a haptic that ramps as you close in. BUILT FOR THE JOB, NOT THE LAB • Auto-lock freezes the axis you're tracking so it can't jump while you work. • A heavy haptic snaps the instant you hit dead level — you feel it, gloves on. • Near level, it reads the pitch in inches per foot, in the fraction you work in. • Sensor-fused from the accelerometer and gyroscope for a bubble that's steady and quick at once. • Big, high-contrast readout and thick borders sized for gloved hands and bright sun. SAVE THE PROOF Tap Save and Plumb Level stores the reading with a snapshot of the vial exactly as it read. Everything lands in your Saved ledger: time-stamped, titled, with notes and an optional jobsite location stamp. SHARE A CLEAN RECORD Export your saved readings as a PDF or PNG ledger, or back the whole set up to a .plumb file. Turn on Custom Branding to stamp your own business name, contact info, and logo on every export — a tidy record for the client or your own files. WORKS WITH ZERO BARS Everything runs on the device. No account, no login, no cloud, no network needed — check level in a basement, a bare shell, or the middle of nowhere. WHO IT'S FOR Carpenters, masons, framers, tile setters, electricians, plumbers, cabinet and shelf hangers, inspectors, and DIYers — anyone who needs plumb, level, and a true angle, fast.

Your readings and snapshots never leave the phone unless you send them yourself with the share sheet.
