TargetLock

AR Distance Measurement

$0.99 · Designed for iPad. Not verified for macOS.

TargetLock 1.1 adds a clearer two-tap AR measuring flow, confidence tips, history sharing, custom height units, overlays, haptics, and app version info. TargetLock is an AR distance measurement app for iPhone and iPad. It helps you estimate the distance to a visible person, pet, or object when you know the target's real-world height. The app uses a simple two-tap measuring flow. Point the camera at the target, tap the top, tap the bottom, choose a height preset or enter a custom height, and TargetLock calculates an estimated distance using ARKit camera tracking and camera intrinsics. What's new in version 1.1: - Clearer measurement results with confidence labels and practical tips - Height entry in meters, centimeters, or feet and inches - Remembered custom height for faster repeat measurements - Current-session history with details and sharing - Share All export for session measurements - Optional grid and crosshair overlays for alignment - Haptic feedback setting - First-launch tutorial and improved in-app help - App version and build shown in Settings TargetLock is designed for quick field estimates, learning, home use, pet and people distance checks, outdoor notes, and situations where a dedicated rangefinder is not available. Key features: - ARKit-based camera tracking - Two-tap top-to-bottom measurement - Height presets for adults, children, and dogs - Custom height input in multiple units - Distance display in meters, feet, or both - Confidence percentage and Good/Fair/Low label - Tips for improving low-confidence measurements - Undo and Reset controls - Optional grid and crosshair guides - Pinch-to-zoom with corrected distance calculation - Session measurement history - Share individual measurements or the full session - Works offline after installation TargetLock uses stadiametric rangefinding: it compares the known real-world height of the target with the target's height on screen and the camera focal length provided by ARKit. The result is an estimate, not a certified survey measurement. For best results: - Keep the target fully visible - Tap the true top and bottom carefully - Use the most accurate target height available - Measure in good lighting - Keep the device steady - Avoid steep camera angles - Move closer when the target is very small on screen Privacy is simple: TargetLock works locally on your device. It does not require an account, subscription, internet connection, location access, analytics SDK, advertising SDK, or backend service. Camera access is used for the live AR view and on-device measurement. Camera images and measurements are not uploaded by the app. TargetLock is an estimation tool for general utility and education. It is not intended for medical, surveying, construction-safety, emergency, weapon, or certified professional measurement use.

TargetLock 1.1 focuses on making AR distance estimates clearer, faster, and easier to review after each measurement. New and improved: - Clearer measurement results with confidence labels - Practical tips when confidence is Fair or Low - Height entry in meters, centimeters, or feet and inches - Remembered custom height for faster repeat measurements - Current-session measurement history - Measurement detail view - Share a single measurement from its detail screen - Share All export for the current session - Optional crosshair overlay - Optional grid overlay - Haptic feedback setting - First-launch tutorial - Help-accessible tutorial - App version and build number shown in Settings - Improved accessibility labels and hints - Dynamic Type support on key text surfaces - Reduce Motion handling for measurement marker animations - Clear All confirmation for measurement history This release keeps TargetLock local and privacy-focused. The app still works offline after installation, does not require an account, does not use location services, and does not upload camera images or measurements. TargetLock remains an estimation tool for general utility and education. Accuracy depends on lighting, device stability, camera tracking, tap precision, target alignment, and the accuracy of the height value you enter.
