Ruler Inches

iOS Universel / Utilitaires

Ruler Inches is a 4-in-1 precision measurement toolkit that replaces four single-function apps with one polished, professional tool.

■ SCREEN RULER
Place your iPhone on any flat surface and instantly measure objects up to the screen length. Drag the start and end markers to measure precisely. Supports both inches and centimeters. Pinch to zoom for finer tick-mark resolution. Calibrate to your exact screen PPI using a standard credit card for maximum accuracy.

■ AR TAPE MEASURE
Use your camera to measure real-world distances in augmented reality. Tap to set a start point, then tap again to measure the distance — displayed live on-screen as you move. Multi-point mode lets you chain measurements to calculate total path length. Works in any lighting with ARKit plane detection.

■ SPIRIT LEVEL
Three measurement modes — Landscape, Portrait, and Surface — with a real-time bubble indicator and precise angle readout. Turns green and triggers haptic feedback the moment you reach perfectly level. Lock mode freezes the reading so you can work hands-free.

■ PROTRACTOR
Measure angles by tilting your device against any surface. Real-time angle display updates as you move. Tap Lock to freeze the current reading; tap Zero to set a custom reference baseline and measure relative angles.

■ MEASUREMENT HISTORY
Every measurement you save is logged with tool type, value, unit, and timestamp. Add notes like "Living room wall" or "Door frame width" for easy reference. Filter by tool type, tap any entry to see full details, or swipe to delete. Clear all with one tap.

■ WIDGETS
Add the home-screen widget for one-tap access to all four tools. The lock-screen widget shows your last measurement at a glance — no need to unlock.

■ DESIGNED FOR PRECISION
• Measurements displayed in large, readable type — easy to see from a distance
• Haptic feedback on every action: save, lock, zero, clear
• Force light mode for consistent readability in any environment
• Dashboard shows last measurement per tool so you always know where you left off
• iPad layout with NavigationSplitView sidebar
• App Store review prompt after third measurement — because we earn it

Whether you're a DIYer hanging pictures, a contractor checking surfaces, a teacher measuring in the classroom, or just someone who needs a quick measurement without hunting for a physical tape — Ruler Inches has you covered.
