Laser-sharp alignment.
Instant room measurements.

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

0 mm / 1 m · 0 in / 4 ft · calibrated ±0.02°

Spirit level

Bar, bullseye and edge

Read degrees, percent slope, roof pitch or mm per metre. Two-point reversal calibration, hold, relative zero and a beep at 0.0°.

Laser camera

Lines locked to gravity

Level and plumb lines on the live camera for frames, shelves and posts — plus a protractor and clinometer. Save the photo as proof.

Tape measure

From a stance or a photo

Distance and height from the camera's tilt, or dimensions drawn on a photo scaled by a card, a sheet of paper or a door — with perspective correction.

Sheets

PDF and CSV

Rooms, readings, wall areas, paint and tile quantities and a level log, on a sheet with an architectural title block.

Built for real work

Hanging pictures — a gallery wall on one laser line, first time.
Furniture and shelves — level, plumb and square without a second pair of hands.
Renovation — wall areas net of doors and windows, paint and tiles to buy.
Construction and carpentry — slopes, roof pitch and a pass/fail level log for the record.

Honest about accuracy

Every camera or photo measurement shows its expected error, and estimates are rounded to what the method can deliver. Phone sensors are calibrated against themselves with the reversal method used for spirit levels. Verify critical dimensions with a tape before cutting.

Plumbora Pro removes all ads and unlocks the laser protractor and clinometer, unlimited measurement photos without a watermark, saved camera measurements, wall and material estimates, a project for every room, PDF and CSV export and the acoustic zero-angle assistant. Yearly (with a 3-day free trial), monthly, or once for life.
