TraceLab – Your Pocket Video Motion Lab A powerful alternative to Tracker – turn any video into a motion analysis lab. Turn any video on your phone into a powerful motion analysis lab. Whether you’re a student exploring physics, a teacher designing engaging lessons, or a curious enthusiast, TraceLab makes complex motion tracking and data analysis as easy as shooting a video. II. Core Features 1. From Video to Data in Three Steps Step 1 – Flexible Video Source Shoot experiments directly in the app or import any existing video from your photo library. Step 2 – Precise Setup Trim clips to focus on key moments. Set scale and coordinate axes (Cartesian or polar) to transform the video into a real measurement space. Step 3 – Intelligent Object Tracking Manually mark points or use AI‑powered segmentation and tracking to handle single or multiple moving objects, even in complex backgrounds. 2. From Data to Insights at a Glance Comprehensive Data Panel Get real‑time tables of all trajectory points. Add computed variables like velocity and acceleration, or create custom formulas for advanced research. Powerful Visual Charts Automatically turn data into intuitive charts. Use multi‑touch to zoom and pan, and apply curve fitting to uncover the math behind your experiments. One‑Tap Export & Share Seamlessly export high‑resolution charts, data tables, or annotated analysis videos – perfect for reports, lesson plans, or collaboration. III. Key Use Cases - Sports Science – Analyze a basketball arc, measure golf club head speed, and optimize athletic performance. - Physics Teaching – Verify free fall, study pendulum motion, demonstrate momentum conservation – bring lab experiments to life. - Everyday Discovery – Measure your pet’s speed, analyze roller‑coaster acceleration, or record plant growth. - Engineering – Evaluate vibration frequencies, test prototype motion, and perform quick preliminary validations. IV. Why TraceLab? - Lab‑grade accuracy, consumer‑friendly ease – we pack professional analysis tools into a smooth mobile experience. - AI‑boosted efficiency – intelligent tracking cuts manual labeling, letting you focus on the science. - One tool, endless possibilities – from classroom to sports field, home to workshop – your universal key to motion analysis. V. Download Now Download TraceLab for free and run your first video analysis experiment. Unlock advanced features for unlimited video analysis, AI tracking, and full data export. “The science inside your video – motion made visible.” Terms of Service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: http://tracelab.solarsight.cn:8705/privacy

Turn any video into real motion data — right on your iPhone. VidMoLyze is built for physics and math classrooms. Record a dropped ball, a rolling cart, a pendulum, or any motion you want to study, then calibrate, track, and export clean position, velocity, and acceleration data — ready for Excel, Google Sheets, or Python. HOW IT WORKS • Record with a locked shutter speed for crisp, trackable frames • Calibrate using a known real-world measurement (like a meter stick) in your shot • Set your origin and axes to match your desired coordinate system • Track your object frame-by-frame with precise manual placement- zoom in for accuracy • Export a clean CSV data file — frame, time, position, velocity, and acceleration for every point BUILT FOR THE CLASSROOM Existing motion analysis tools are either locked to a paid app, limited to desktop, or produce exports too messy to use in a normal class period. VidMoLyze is free, works entirely on your device, and gets students from raw video to usable data fast enough to fit inside a single 55-minute class. WHO IT'S FOR Physics and algebra teachers covering kinematics, projectile motion, free fall, circular motion, or terminal velocity — and any student who wants to see the math behind real movement, not just a textbook diagram. VidMoLyze is free to use, supported by a small, non-intrusive ad. If you find it useful, you can support further development by making a donation at ko-fi.com/michaelw805 (there is a link in the (i) About page in the app.
