## Description

AR Measuring Tool: Real-time measurement of distance, angle, area and volume via your mobile phone. Supports switching between metric and imperial units.

AR Protractor is a portable measurement tool built on augmented reality that turns your phone into a portable rangefinder, protractor and volume meter. No extra hardware is needed — just open the camera and aim at a flat surface to get accurate measurement results instantly.

## Main Features
• Rangefinder: Continuous single-point measurement with real-time display of segment length and total cumulative distance
• Protractor: Calculate arbitrary planar angles via three-point measurement
• Area Measurement: Two modes available — polygon and circle
• Volume Measurement: One-tap calculation for cuboids, cylinders and irregular solids (frustum method)
• Unit Conversion: Meters, centimeters, millimeters, feet, inches; cubic meters, liters, cubic feet, gallons
• Marker Size Adjustment: Customize the size of measurement markers to suit your usage habits

## Premium Features
Two unlocking options: yearly subscription (3-day free trial, cancel anytime, auto-renews yearly) or one-time purchase for permanent unlock. Unlock Angle Measurement, Area Measurement, and all volume features (Box / Cylinder), ad-free.

## Privacy & Support
We value your privacy. All AR measurement processing happens locally on your device, and none of your environmental data will be uploaded.
