The problem
What you feel and what is actually happening in your swing are rarely the same thing. Most golfers have a theory — and most theories are wrong.
Feel ≠ Real
The disconnect between felt movement and actual movement is the most significant barrier to lasting improvement
Every lesson
Without objective data is based on subjective observation — not what the physics and biomechanics are producing
The data
Biomechanics and physics swing data you need exists inside your swing. It just hasn't been visible — until now
Video capture
Works with face-on video for full joint-pair tracking. Set golfer gender, handedness, player level and club type for calibrated analysis
What it does
SwingTrace processes your swing at the frame level against physics-derived biomechanical baselines — supports coaching intuition, not generic templates.
All video formats up-sampled to 240fps, revealing detail that neither the camera nor the human eye can detect. A 2.2× floating touch loupe projects the target zone above your thumb, so angle reticles sit exactly on the club shaft and body landmarks, even on a phone screen outdoors.
AI kinematic sequencing maps your arms, torso, and hip & leg dynamics against a physics-based benchmark. See immediately where your sequence breaks down and in which direction.
Built on the biomechanical framework from The Physics & Biomechanics of Golf by Barrie Van Proctor.
Designed specifically for the driving range with thumb-friendly controls, collapsible telemetry panels, and gesture-safe margins while holding a club. Tap “Add to Home Screen” in iOS Safari or Android Chrome to launch SwingTrace full-screen like a native app.
After each analysis, commit to one biomechanical metric as your practice focus. SwingTrace tracks it across every subsequent swing and displays a sparkline trend chart — so you can see objectively whether the work is paying off.
Practice: 1 focus goal · Perform: 3 goals · Coach: 3 goals per student
Subscribers land on the Progress Dashboard — a home screen showing swing history by date, active focus goals, and trend sparklines. Your progress laid out in one view, every time you sign in.
AI-powered coaching commentary generated after every analysis. Includes a Your Focus priority — the lowest-starred trainable metric surfaced with a 35-word actionable instruction. Clarity, not noise.
SwingTrace uses computer vision and in-browser AI pose-detection to automatically detect your P2–P7 swing phase markers. The app places the positions for you — no timeline scrubbing required, just a quick check and confirm.
Your dedication to improvement is recognised in the app. Progress through six ranks — Casual, Player, Committed, Power User, Expert, and Elite — visible in your Account tab.
Subscriber features require a Practice, Perform, or Coach plan.
The process
Record directly with your phone's 60, 120, or 240fps slow-motion camera, or pick any clip straight from your camera roll.
SwingTrace automatically detects your P2–P7 swing positions using pose estimation, then processes every frame: tracking hip rotation, shoulder coil, arm path, and club trajectory against biomechanical baselines. In your browser.
Review your swing frame by frame with position overlays. See precisely where your sequence diverges from optimal. Subscribers track progress across sessions with Focus Tracking and the Progress Dashboard.
What golfers say
"This has really helped enhance my biomechanics background. It also allows a speedy improvement plan to be built around what the numbers show."
"Used SwingTrace AI to assess a number of my players. The detailed data identified effieciency gains and helped drive-up club speed."
