About this app

AccuScale turns your Android phone or tablet into a professional measurement tool for construction plans, architectural blueprints, and job-site photos.

Whether you're a contractor verifying room dimensions, an architect reviewing drawings on-site, or a designer estimating material quantities — AccuScale delivers precise real-world measurements in seconds.

No tape measure. No scale bar math. No guessing.

★ HOW IT WORKS ★

① OPEN — Import any JPG, PNG, or multi-page PDF blueprint from your device, or photograph a physical plan with your camera.

② CALIBRATE — Tap two points on any element with a known length (a door, a wall, a standard feature). Enter the real measurement and AccuScale locks in your scale automatically.

③ MEASURE — Tap any two points on the plan. AccuScale instantly calculates and displays the true real-world distance.

④ ANNOTATE & EXPORT — Label each measurement, color-code by room or trade, and export a finished image with all lines and dimensions drawn directly on the plan.
