LevelMate: Bubble Level

LevelMate combines a bubble level, spirit level, angle finder and practical builder calculators in one offline app. Use it for quick alignment checks, camera framing, roof pitch calculations, concrete volume, tile and paint coverage, brick/block estimates, stair layouts, on-screen measurements and unit conversions—without creating an account. LEVEL, PLUMB AND ANGLES • Bubble Level — check horizontal alignment with a clear real-time bubble and colour feedback. • Plumb Mode — check vertical alignment for walls, posts, frames and other upright surfaces. • Angle Mode / Inclinometer — view the device angle while adjusting a surface or object. • Calibration — calibrate on a known level surface and choose a suitable tolerance for the task. CAMERA LEVEL Use the live camera grid and level guide to frame photos, videos and visual reference points. Camera Level displays a local preview only. LevelMate does not record, save or upload camera images or video. SIX BUILDER CALCULATORS • Roof Pitch Calculator — enter rise and run to calculate pitch ratio, roof angle and slope. • Concrete Calculator — estimate concrete volume and the approximate number of bags required. • Tile Calculator — calculate room area, tile coverage, tile quantity and box count. • Paint Calculator — estimate surface coverage and the number of paint cans required. • Brick / Block Calculator — estimate wall materials from wall and unit dimensions. • Stair Calculator — plan a basic stair rise-and-run layout. SCREEN RULER AND UNIT CONVERTER • Screen Ruler — take quick measurements directly on your device screen. • Unit Converter — convert metric and imperial values for length, area, volume, weight and angles. PRIVATE, LOCAL AND OFFLINE LevelMate works locally on your device. No login or cloud account is required. The app contains no advertising or subscriptions, and its core tools work without an internet connection. Camera, motion, orientation and calculation information is not uploaded by LevelMate. IMPORTANT MEASUREMENT NOTE Sensor-based readings can vary by device, calibration, protective case, surface and positioning. Calibrate before use and verify important measurements with suitable calibrated equipment. LevelMate is a practical aid and should not be the sole measuring method for safety-critical or regulated work.
