The problem

You think you know what's wrong with your swing

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

Analysis your eye cannot perform

SwingTrace processes your swing at the frame level against physics-derived biomechanical baselines — supports coaching intuition, not generic templates.

See the split-second that costs you distance

240fps slow-motion capture reveals your impact position with a precision no eye can match. Review frame by frame, at your own pace, as many times as you need.

Supports 60 / 120 / 240fps video or convert slow-motion files on any relatively modern device.

Know exactly where your power leaks — and why

AI kinematic sequencing maps your arms, torso, and hip & leg dynamics against a physics-based benchmark. Ascertain immediately where your sequence breaks down and in which body segment or force direction.

Built on the biomechanical framework from The Physics & Biomechanics of Golf by Barrie Van Proctor.

Results in minutes. No cloud wait. No privacy compromise.

All analysis runs locally in your browser — your swing video is never uploaded to a server. Results are fast, comprehensive and completely private.

Works on any modern browser — desktop, laptop, tablet, or 'phablet'. No installation required.

The process

From video to insight in a few minutes

  1. Record or upload your swing

    Use your phone's camera at 60, 120, or 240fps. Set up face-on — record yourself, or have a friend film you. Upload the clip into SwingTrace and trim to just before the takeaway through to follow-through.

  2. AI maps your kinematic sequence

    Check and edit P-positions P2–P7 (full instructions in app). SwingTrace processes every frame: tracking hip and shoulder pivot, arm and hand path, leg and ankle dynamics using advanced computer vision. In your browser. Data is only sent for specialist AI analysis for a written summary. Minimal waiting for a server response.

  3. Understand exactly what's happening

    Review your swing frame by frame with position overlays. See precisely where your sequence diverges from optimal. Share the annotated frames directly with your coach.

What golfers say

Real results from real swings

"This has really helped enhance my biomechanics background. It also allows a speedy improvement plan to be built around what the numbers show."
"I've had lessons for twenty years and no one ever showed me frame by frame what my transition was doing in terms of forces and joint motion. Once I saw the data, the changes needed were obvious."
