A surface that looks level can still leave a shelf crooked, a ramp too steep, or a cut at the wrong angle. Angle Finder turns your iPhone into a live bubble level and angle toolkit, so you can measure before small errors become costly rework. Whether you are hanging cabinets, setting posts, checking a roof pitch, or building a ramp, guessing is frustrating. Angle Finder gives you clear live readings, practical calculators, and a saved measurement log you can return to later. MEASURE WITH CONFIDENCE • Follow a responsive bubble that moves toward center and clearly confirms when the surface is level • View pitch, roll, and yaw with capture-quality feedback • Lock a live reading or set a relative reference to compare against another surface • Calibrate for the surface you are working on • Measure in degrees, percent grade, or slope ratio • Use optional spoken feedback when your hands are busy TOOLS FOR REAL PROJECTS • Quick Level for everyday checks • Slope Calculator for rise, grade, and ratio • Digital Protractor for measuring from a reference angle • Two-Point Measurement for the angle between device orientations • Angle Comparator for checking consistency across readings • Construction tools for miter angles, roof pitch, stairs, and common angle references • Angle Calculator for conversions, angle arithmetic, and trigonometric functions • ADA ramp slope checks and shareable compliance reports for reference SAVE THE WORK, NOT JUST THE NUMBER • Name and save unlimited measurements to your on-device history • Search and filter saved readings by measurement mode • Share individual readings and tool results • Export selected measurements as CSV, JSON, a text summary, or a professional report with statistics BUILT FOR REAL LIFE • DIYers hanging shelves, pictures, cabinets, and fixtures • Contractors and carpenters checking level, slope, cuts, and framing • Roof, deck, stair, and ramp projects • Accessibility professionals reviewing ramp slopes against common ADA guidance • Automotive work that requires checking tilt and orientation • Students and educators exploring angles and trigonometry PRIVATE BY DEFAULT No account is required.
