## What is RulerApp?

Turn your iPhone or iPad into a precise on-screen ruler. Hold any small object against the screen and read its exact size — no tape measure, no guesswork.

FEATURES

• Accurate out of the box — no manual calibration. Ruler scale is calculated from your exact device's screen density.
• Switch between centimeters, inches, or both at once.
• Drag to drop a crosshair anywhere and read precise X/Y measurements from the corner.
• Toggle a grid overlay (off, major lines, or major + minor) for finer alignment.
• iPad extras: hover measurements with a trackpad or Apple Pencil, and keyboard shortcuts (U for units, G for grid) with a hardware keyboard.

Simple, fast, and always in your pocket.
