Real-time AR arrow overlay on camera view showing inferred flow direction
Manual input mode for marking and saving known flow direction on specific meter models
Library of common meter models with pre-calculated flow direction indicators
Add photo notes and annotations for future reference

Target Users: Plumbing and water utility field technicians who frequently need to determine flow direction on meters

Revenue Model: $9.99 one-time app purchase or $2.99/month subscription for cloud backup and model database updates
