Smart Distance is an AR-based distance measurement app that uses your smartphone's camera to measure real-world distances with ease. Powered by Google ARCore technology, the app automatically detects your device's capabilities and selects the optimal measurement engine for the best accuracy.

[Measurement Engine Tiers]
• Premium (ToF/LiDAR): Uses hardware depth sensors for professional-grade accuracy (±2cm)
• High (Depth API): Software-based depth estimation with high precision (±5cm)
• Standard (ARCore): Plane detection and feature tracking (±10cm)
• Basic (Camera): Basic camera-based estimation for devices without AR support

[How to Measure]
1. Tap the Measure button on the main screen
2. Point your camera at the object you want to measure
3. Wait for the tracking to stabilize (move slowly)
4. Align the center target with the object
5. Tap the screen to capture the measurement

[Tips for Accurate Measurement]
• Ensure good lighting conditions
• Move your device slowly during initialization
• Keep a steady hand while measuring
• Measure surfaces with visible features and textures
• Avoid reflective or transparent surfaces
• Optimal distance range is 0.5m to 5m
