ARuler Pro 2026

Field-grade AR measurement powered by AR technology. Lengths, heights, areas, multi-segment paths. Sub-cm precision on LiDAR. Fully offline. Zero data collection.

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 • LiDAR recommended for best precision
