Turn your iPhone Pro into a physics laboratory. LiDAR-powered motion tracking with real-time graphs. 8 free recordings, then $4.99 for unlimited. No subscriptions!

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.
