## Description

**All-in-One Measuring Tool** is a versatile measuring suite that combines a ruler, protractor, and bubble level with AR-powered camera measurements. Use the AR Ruler & 3D Camera Measure to capture distances, heights, and angles directly through your camera. Features include AR Tape Measure and Room & Object Measurement for quick, on-site dimensions, delivering instant accuracy.

The app also includes a traditional **Ruler App** with unit conversions (mm↔in, cm↔in), length calculations, area and plane measurements, and a four-mode system (point, line, plane, level). A **Protractor** offers camera-based angle measurements between markers, while a **Bubble Level** helps with horizontal and vertical calibration. Lightweight, intuitive, and stylish, it’s your go-to tool for measuring length, angles, and calibrating spaces on the go.
