Angle Finder

Angle Finder turns your phone into a fast and easy-to-read angle tool. Use Direction mode to compare two directions: place the phone against your first reference, tap ZERO, then rotate the phone to read the relative angle. Lift the phone to measure slope and tilt using the clear degree display. Features include instant measurements to one decimal place, one-tap relative zero, automatic direction and slope modes, a smooth high-visibility display, and screen-awake operation while measuring. The app works completely offline and contains no advertising, accounts, analytics, tracking, or unnecessary permissions. Angle Finder is useful for quick measurements in workshops, construction projects, woodworking, installation work, and everyday household tasks. Measurement accuracy depends on the quality and calibration of the sensors in your device. Angle Finder is a convenient reference tool and is not intended to replace certified measuring equipment for safety-critical or professional verification.
