Inclinometer Level - Plumbrule

Level & Ruler in one app: Plumbrule is a bubble level and a ruler in mm and inches, plus an inclinometer, a protractor and a reading log. It is named after the carpenter's plumb rule, a straightedge and a level in one board, and it brings that same idea to your phone as one clean, precise measuring tool. ■ Ruler in millimeters and inches • Metric scale on the left edge, inches (1/16) on the right, both shown at once • Drag two lines to measure; the reading follows your finger • Choose fractions (1/16, 1/32) or decimal inches • Add segment: measure objects longer than your screen and get the total length • Calibrate once with a bank card, a coin or any length you know, so the on-screen scale matches your display exactly ■ Bubble level and inclinometer • Lay the phone flat for a bullseye level with X and Y angles • Stand it on an edge and it becomes a tube level; the vial and the reading turn with the phone • Shows Level or Plumb, turns yellow and gives a short vibration the moment you are within tolerance • Units: degrees, percent grade, mm per meter, inches per foot and roof pitch (x/12) • Hold freezes the reading so you can check it after moving the phone • Zero measures relative to any surface, which is great for matching an existing angle or slope • Two-step flip calibration removes your phone's sensor offset ■ Protractor • Put the corner at the pivot, drag both arms, then read the angle and its supplement ■ Measurement log • Save any reading with one tap • Add a label so you remember what you measured • Share your saved readings as text or CSV ■ Built like a tool • Graphite theme that is easy on the eyes, or a high-contrast Daylight theme for outdoors • Keeps the screen on while you measure • Available in 30 languages • No account and no sign-up ■ Getting started • Calibrate the ruler once with a bank card, a coin or any length you know • Run the two-step flip calibration for the level • Lay the phone flat for the bullseye level, or stand it on an edge for the tube level • Pick your unit: degrees, percent grade, mm per meter, inches per foot or roof pitch • Tap once to save a reading to the log, add a label and share it ■ Who it is for • Anyone hanging a picture or shelf who wants to check level or plumb • DIYers and carpenters who need a quick angle finder, slope gauge or pitch reading • Anyone measuring a small object in millimeters or inches • People who want to keep a record of their measurements ■ Tips • Calibrate the ruler and the level for best results • Use Zero to match an angle from one surface to another • Use Hold to freeze the reading, then look at it after moving the phone • Switch to the Daylight theme when working outdoors • Use Add segment for anything longer than your screen ■ FAQ • Do I need an account? No. There is no account and no sign-up. • Where are my readings stored? Your readings stay on your phone. • Are there ads? A small banner ad appears only on the Log and Settings screens, never over the ruler, level or protractor. • How accurate is it? Accuracy depends on your phone's screen and sensors. Calibrate for best results and double-check critical work with a physical tool. ■ Privacy • No account, no sign-up; your readings stay on your phone • Privacy policy: https://tanzsoft.com/plumbrule/privacy.html Plumbrule: a ruler, bubble level, inclinometer and protractor in one tool.
