## x of t Description
Turn your iPhone Pro or iPad Pro into a powerful physics laboratory! Motion Tracker uses advanced LiDAR depth sensing to measure and analyze real-world motion with professional accuracy.

 PERFECT FOR PHYSICS STUDENTS & EDUCATORS

Whether you're studying kinematics, conducting experiments, or just curious about motion, Motion Tracker makes complex physics concepts visual and interactive. Record distance, velocity, and acceleration data in real-time, then analyze it with beautiful, interactive graphs.

PROFESSIONAL MOTION ANALYSIS

• Position Tracking - Measure distance changes over time with millimeter precision
• Velocity Graphs - See how speed changes throughout motion
• Acceleration Analysis - Visualize forces and rate of change
• Export to CSV - Use your data in spreadsheets, Desmos, or other analysis tools
• Copy to Desmos - Share directly with the popular graphing calculator

TWO TRACKING MODES

MANUAL POINT TRACKING
Perfect for large targets like walls, people, or objects. Simply tap a point in your environment and watch as the app tracks its distance in real-time. Great for tracking walking motion, analyzing projectiles, or measuring any large-scale movement.

COLOR TRACKING
Ideal for physics experiments with small, brightly colored objects. Tap any colored object (like a tennis ball pendulum!) and the app automatically follows it. Perfect for:
• Pendulum experiments
• Spring oscillations
• Ball drops and bounces
• Any setup with a bright marker

 MATCHING GAME MODE

Test your skills! Follow a target motion pattern and see how closely you can match it. Great for:
• Understanding velocity and acceleration
• Practicing smooth motion control
• Learning kinematics concepts
• Classroom competitions

PRIVACY FIRST

Motion Tracker respects your privacy:
• No data collection or tracking
• All processing happens on your device
• No account required
• Works completely offline (except purchases)
• Your data never leaves your phone
• No ads or analytics

Your motion tracking data is yours and yours alone.

REQUIRES LIDAR SENSOR

This app requires a device with LiDAR for accurate depth measurements:
• iPhone 12 Pro / Pro Max or newer Pro models
• iPhone 13 Pro / Pro Max
• iPhone 14 Pro / Pro Max
• iPhone 15 Pro / Pro Max
• iPhone 16 Pro / Pro Max
• iPhone 17 Pro / Pro Max
• iPad Pro 11-inch (2nd generation or newer)
• iPad Pro 12.9-inch (4th generation or newer)
• iPad Pro 13-inch

Standard iPhone and iPad models do not have LiDAR sensors and cannot run this app.

KEY FEATURES

• Real-time distance measurement using LiDAR
• Position, velocity, and acceleration graphs
• Manual point and automatic color tracking
• Matching game for interactive learning
• Data export to CSV format
• Desmos integration for advanced analysis
• Kalman filtering for smooth, accurate data
• Interactive graph zooming and panning
• Free trial: 8 recordings to try it out
• One-time purchase: $4.99 for unlimited use

EDUCATIONAL APPLICATIONS

• High school physics labs
• College kinematics courses
• Homeschool science experiments
• STEM demonstrations
• Science fair projects
• Understanding graphs and motion
• Data collection and analysis practice

 EXAMPLE EXPERIMENTS

• Pendulum period and amplitude
• Free fall and gravity (don't drop your phone!)
• Spring constant measurements
• Harmonic motion analysis
• Walking and running speed
• Projectile motion tracking (don't throw your phone!)
• Collision analysis (don't...)

 NO COMPLICATED SETUP

Just point your device, tap a target, and start recording. The intuitive interface gets you collecting data in seconds, not minutes. Whether you're a student conducting experiments, a teacher demonstrating concepts, or simply curious about physics, Motion Tracker gives you laboratory-grade tools in your pocket.

Download now and transform your iPhone Pro into a physics lab!
