## What is ARuler Pro 2026?

ARuler Pro is a field-grade AR measurement tool built on AR technology, designed for designers, contractors, on-site surveyors and anyone who needs precise everyday measurements.

Technical Specs
• Engine: AR rendering + 3D visualization + simd vector math
• LiDAR devices (iPhone 12 Pro / 13 Pro / 14 Pro / 15 Pro / 16 Pro and Pro Max): sub-centimeter depth sampling
• Non-LiDAR devices: AR plane detection and feature-point solving
• Units: m / cm / mm / inch / ft, bidirectional metric/imperial conversion
• Local storage via SwiftData, fully offline, no account required

Measurement Capabilities
• Single-segment distance: straight-line length between two points
• Multi-segment paths: continuous multi-point measurement with cumulative length
• Height measurement: vertical distance from ground to selected point
• Area estimation: closed polygon vertex paths auto-computed
• Level calibration: gyroscope-assisted reference plane locking
• Haptic feedback: confirms endpoint placement

Who It's For
• Interior design and renovation contractors
• Real-estate field surveying
• Logistics package dimensioning
• Geometry teaching and STEM learning
• Outdoor distance and object-height estimation

Privacy & Compliance
• Zero user data collection
• No network access requested
• Camera permission used only for AR rendering
• ITSAppUsesNonExemptEncryption = false

Requirements
• iOS 17.0 or later, iPhone only
• AR-capable device required
