Protractor + Angle Finder - AR 1.99.52

The Protractor + Angle Finder – AR presents itself as a highly precise application designed for accurate angle measurement and surface leveling. Its comprehensive suite of tools extends beyond basic functionalities, incorporating features such as a protractor, bubble level, spirit level, ruler, pitch gauge, inclinometer, and measurement recorder. Notably, the app is available free of charge, making professional-grade measurement accessible to a broad user base.

Its interface showcases an industry-leading, responsive design that facilitates intuitive operation. Users can employ the bubble level or protractor to align household objects with precision. The app supports measuring angles and slopes via the integrated level tools, effectively turning your device into a pocket-sized protractor and spirit level. Additional features include flashlight illumination for low-light conditions, a compass, camera-based measurement, and various tools all consolidated within a single interface.

The application excels in providing detailed functionality for both casual and professional use. It offers a 360-degree angle measurement capability, with automatic bubble levels suitable for various orientations—90°, 180°, 270°, and full 360°. The surface level tool allows for precise leveling of surfaces with degree-based output, while the clinometer measures angles along all edges of the device by utilizing its sensors. Stored target angles can be recalled quickly from memory or entered manually to facilitate repetitive measurements.

One of the application's salient features is its calibration system. A 6-step calibration assistant ensures measurements are accurate to within 0.1°, with independent calibration of the surface level and protractor enhancing precision further. Acoustic alerts notify users when approaching specified target angles or common orientation points such as cardinal directions.

The intuitive design adapts dynamically depending on device orientation, seamlessly transitioning between surface level view and 360° protractor display. The app also includes stability indicators that reflect the rate of change in measurements, aiding users in achieving optimal accuracy.

Overall, this measurement tool integrates advanced digital features—such as native drawing capabilities—to provide clear and fluid displays. Its versatility extends to measuring not only angles and slopes but also lengths and heights using the device’s accelerometer (g-forces). Whether used as a traditional spirit level, digital inclinometer, or multifunctional angle meter, this app delivers high precision suitable for various professional and DIY applications.
