## What is Ruler & Level?

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.
