Plumbora: AR Measure & Level

Laser-sharp alignment. Instant room measurements.

Plumbora turns your phone into a calm, precise instrument case: a calibrated spirit level that beeps at zero, laser level and plumb lines on the live camera, a tape measure that works from where you stand or from a single photo — and a clean measurement sheet at the end.

WHY PLUMBORA
• A level you can trust: two-point reversal calibration, exactly like a real spirit level.
• Readings that never jitter: a gyro + accelerometer filter and tabular figures, smooth at 60 fps.
• Honest accuracy: every camera or photo measurement shows its expected error.
• Quiet design inspired by professional instruments — no fake wood, no clutter.
• Camera and motion sensors are processed only on your phone. No account, no uploads.

FEATURES
• Precision Spirit Level & 2D Bullseye — bar, bullseye and edge modes; degrees, percent slope, roof pitch (in/ft) or mm per metre; hold, relative zero and a beep and haptic tick at exactly 0.0° or 90.0°.
• Live Camera Laser Crosshair — level and plumb lines locked to gravity on the live camera, for hanging pictures, setting shelves and checking posts; save the photo as proof.
• Laser protractor and clinometer — any angle with 15° snaps, roof pitch and slope from a distance (Pro).
• Camera Distance & Height — aim at the base, then the top: distance and height from the camera's tilt and height.
• Photo Dimension Markup — scale a photo with a card, a sheet of A4 or Letter or a door, correct perspective with a rectangle, then draw dimension arrows, wall areas and openings.
• Room Area Calculator — floor area free; walls net of doors and windows, paint (litres or gallons), floor tiles and baseboard with Pro.
• Roof Pitch & Slope Clinometer — read pitch in x/12 or slope in percent.
• Edge ruler — a true-scale screen ruler in cm or inches, calibrated against a payment card.
• PDF Project Sheets — rooms, readings, areas, materials, a pass/fail level log and dimensioned photos on a sheet with an architectural title block; CSV for spreadsheets (Pro).
• Acoustic zero-angle assistant — beeps faster as you approach level, a steady tone at zero (Pro).
• Imperial (ft-in, 1/16") or metric (m, cm) automatically, light and dark themes.

MADE FOR
• Hanging pictures — a gallery wall on one laser line, first time.
• Furniture assembly — level, plumb and square without a second pair of hands.
• Home renovation — wall areas, paint and tiles to buy.
• Construction and carpentry — slopes, roof pitch and a level log for the record.

PRIVACY
The camera image and the gyroscope and accelerometer readings are processed in real time on your device only. Photos and measurements are stored on your phone and never uploaded. The camera is asked for only when you open the Laser or Measure tool; the level needs no permission at all. Plumbora uses the system photo picker and never asks for your whole library or your location.

Camera and photo measurements are estimates — verify critical dimensions before cutting.
