Every line, dead level.
Plumb One is a pocket laser level that checks its own work. It draws a true line on any wall and tells you the moment you drift. Try a working simulator of it below.
Tilt resolution, self-leveling
Visible beam in a lit room
Lighter than a phone, fits a pocket
Pendulum settling time
Tilt it. Watch it find level.
A simplified model of the pendulum: drag the device and the beam swings, then settles in about 0.4 seconds. Press Mark to save the line.
Level
Drag the device, use arrow keys when focused, or the slider. Past ±5° the pendulum hits its stop and the beam leaves level.

Three moves. No math, no bubble-squinting.
Hold it against the wall and let go. Plumb finds level on its own, then keeps checking while you work.
Stick
Magnet back for studs and steel, pin tabs for drywall, a clamp for tripods.
Aim
A damped pendulum settles in under half a second. The lens ring turns lime when the line is true.
Mark
Follow the line with a pencil. Tap once and the angle is saved for the next wall.
Small enough to forget. Precise enough to trust.
Every part answers one question: is this line really level, and how would I know?
A line that tells you when to doubt it.
Plumb measures its own tilt continuously. If the pendulum has not settled, the beam blinks instead of lying to you.
A second pair of eyes.
Live angle, snapshots and a quiet tone when you are within a hair.
Magnet, pin or tripod.
Three ways to hold a line without holding the tool.
Level and plumb at once.
Tap twice for a crosshair. Perfect for tile starts and cabinet runs.
40 hours. USB-C.
A pocket power bank is enough for a whole renovation.
Hang a gallery wall in one pass.
Set one centre line, then hang every frame from it. The planner turns that into nail positions, in centimetres and inches.
- Drag frames and see hole spacing update live
- Copy the measurements to your phone
- Pin tabs leave holes smaller than a nail
For anyone whose eye is better than their level.
Renovators
Cabinet runs, trim, and rails that finish where they started.
Renters
Straight shelves with the smallest possible holes in the wall.
Tilers
Start lines and cross-lines that carry across the whole room.
Picture hangers
Galleries, salon walls and shop displays, spaced by sight.

Is Plumb real? Can I buy it?
No. Plumb One is a fictional product invented as a design and front-end showcase. Nothing can be purchased, prices are illustrative, the pre-order and contact forms only validate and confirm on your own device, and nothing you type is sent or stored.
What is simulated here?
The simulator uses a simplified damped-pendulum model with a ±5° stop and a 0.4 second settling time. It illustrates the idea; it is not a model of any real instrument. The drift chart and planner use plain geometry that is accurate on its own terms.
How accurate would it be?
The concept spec is 0.1° tilt resolution. That is about 1.7 mm of drift per metre, or 21 mm at 12 m. A bubble level read by eye at 1° is ten times that.
Could I see the beam in a bright room?
In the concept, the beam reads clearly out to about 12 m in a normally lit room. In direct sun you would use a target card or the phone readout.
Will the magnet scratch my wall?
The magnet back only holds to steel. For painted drywall the concept uses pin tabs that leave a hole smaller than a sewing needle, or a clamp on a tripod.
