Bubble level, inclinometer, angle finder and roof pitch gauge in one app.
A precision spirit level and inclinometer that works entirely on your phone. Five measuring modes, real calibration, and no ads, no tracking and no account — ever. FIVE WAYS TO MEASURE • Bullseye — a true 2D circular level for tables, shelves, appliances and tripods • Horizontal and Vertical — classic single-axis spirit level for shelves and door frames • Angle — read any incline as degrees, percent grade, mm/m or a 1:X ratio • Camera — point at a roof, ramp or hillside and measure the slope you can see PRO TOOLS • Roof pitch in X:12 rise-over-run, degrees and percent at the same time • Slope presets: drainage 2%, ADA ramp 1:12, roof 15/30/45 degrees, stairs 35 degrees — with a live "how far off" readout • RV and trailer levelling: enter wheelbase and track width, get the exact height to raise each side in cm or inches • Crown moulding compound miter: spring angle and corner angle in, miter and bevel out BUILT TO BE TRUSTED • 180-degree calibration wizard with saved profiles, so a phone case never costs you accuracy • Tolerance bands of 0.1, 0.2, 0.5 or 1.0 degrees with OK / NEAR / OUT states and haptic feedback • Three filters — Fast, Smooth and Precision — plus a live confidence bar built from sensor jitter • Set a relative zero against any surface, then measure everything else against it • Hold to freeze a reading, with automatic save to history • 500-entry measurement history with CSV export PRIVACY BY DESIGN Works fully offline. No internet permission is used for measuring, nothing is uploaded, no analytics, no accounts, no ads. The camera is used only by the camera clinometer and the AR laser line: the picture is processed on the device and is never saved, sent or shared. Whether you are hanging a picture, laying tile, checking a roof pitch, levelling a caravan or cutting crown moulding, the answer is one tap away.
