Pocket Ruler transforms your iPhone into two essential precision tools — a physical ruler and a spirit level — always in your pocket. RULER The on-screen ruler renders at true physical size, calibrated to your exact iPhone model's pixel density. Measure small objects directly on screen in centimetres or inches. Two-finger pan to slide the ruler along longer objects. LEVEL A clean spirit level with three smart layouts: • Flat on a table — 2D bubble shows tilt in both axes • Held upright — rotating horizon line shows left/right roll • Landscape — horizontal bar for surfaces and shelves Tap anywhere to lock a reference angle and measure relative tilt from that point. DESIGNED FOR ACCURACY Every measurement stays on-device. No network connection, no account, no data collection. Just your phone and physics.
