Turn your iPhone or iPad into a professional-grade ruler, protractor, and illuminated drafting board. Unlike standard digital measurement apps that rely on generic screen graphics, Metal Ruler Pro uses a custom hardware scanner to calibrate exactly to your specific device’s pixel density. This means 1 cm on your screen is exactly 1 cm in the real world—every single time. Designed for designers, engineers, crafters, and everyday users, Metal Ruler Pro combines true physical scale with an incredibly intuitive multi-touch physics engine. CORE FEATURES: • True-to-Life Calibration: Automatically detects your specific hardware—from the latest iPhone Pro Max to the iPad Mini and 13-inch iPad Pro—for absolute, real-world physical accuracy. • Light Box Mode: Double-tap the lightbulb to turn your screen into a maximum-brightness, pure-white surface. Perfect for tracing designs, drawing, or reviewing photographic negatives. • Advanced Multi-Touch: Use one finger to drag, or two fingers to rotate the ruler smoothly across the self-healing cutting mat background. • Magnetic Snapping & Drafting Grid: Activate the magnet to pull up a dense, professional drafting grid. The ruler snaps to grid intersections and locks perfectly into 0°, 90°, 180°, and 270° angles for flawless straight-line alignment. • Measurement Lock: Double-tap the ruler body to freeze it in place. Lay physical objects directly on your screen without accidentally ruining your alignment. • Tactile Feedback: Feel every snap and lock with iPhone Taptic feedback, alongside custom mechanical acoustic "tocks" engineered specifically for iPad users. • Instant Conversion: Seamlessly toggle between Metric (CM) and Imperial (IN) units with a single tap. PREMIUM BY DESIGN: No subscriptions. No accounts. No ads. No data tracking. Just a perfectly engineered, professional measurement tool right in your pocket.
