## What is TargetLock?

TargetLock is an AR distance measurement app that helps estimate the distance to a visible person, pet, or object when you know its real-world height.

Point your iPhone camera at the target, choose or enter the target height, then tap the top and bottom of the object. TargetLock uses ARKit camera tracking and camera intrinsics to calculate an estimated distance and show the result in meters and feet.

Key features:
- Two-tap distance measurement
- Common height presets and custom height input
- Meter and feet display
- Optional crosshair and grid overlays for alignment
- Confidence feedback based on tracking and measurement conditions
- Measurement history with sharing/export support
- Diagnostics screen for ARKit and camera capability checks
- First-run tutorial and built-in guidance
- Works offline with local-only processing

TargetLock is intended for quick estimates, education, field notes, and situations where a traditional rangefinder is not available. Measurement accuracy depends on lighting, camera tracking, target alignment, tap precision, and the accuracy of the entered target height.

Privacy: TargetLock does not require an account, does not use location services, and does not upload camera images. Camera access is used only to display the live AR view and perform on-device measurements.
