SwingSense turns two ordinary cameras and a Mac into a golf motion lab. It watches you swing, breaks the swing into events, and compares it against your coach's model swing β automatically, in seconds.
No buttons, no operator, no wading through video. The system is always watching, and only a real swing gets kept.
Two cameras on tripods β one face-on, one down the line. An app guides placement in under 30 seconds. After that, the lesson bay just works.
Cameras stream into a rolling memory buffer. The moment your club hits the ball, the swing is trimmed, saved, and analyzed. Practice swings and walk-bys? Automatically discarded.
SwingSense compares your motion to your instructor's reference swing β spine angle, hip and shoulder turn, tempo, head movement β at each key event: address, top, impact, finish.
A ghost of your coach's swing plays over yours, with a plain-English delta table. Two seconds after impact, you know what to change.
Tour coaches use multi-camera systems that cost thousands per year. Everyone else gets a phone app that guesses. We think your coach's expertise should be the product β not the hardware.
Not a generic "tour average" β comparisons run against the exact model your instructor teaches.
Everything runs on-device. Nothing is recorded unless it's a swing, and footage can be discarded after analysis, leaving only the numbers.
No strobes, no studio, no installed bay. Two tripods, two cameras, one laptop β set up at any range in minutes.
Every swing becomes a data point. Watch your X-factor, tempo, and spine angle converge toward the model over weeks.

This isn't a concept deck. The core pipeline already runs and is benchmarked against motion-capture ground truth.
Every swing the bay captures syncs to the SwingSense app β slow-mo replay with your skeleton overlay, model-swing comparison, and your coach's notes. Here's the shape of it:
Plus a full web dashboard for bigger-screen review after your round β same data, same comparisons, iOS & Android.
We're looking for a handful of golfers and coaches to put the prototype through its paces. No spam β just an email when it's your turn.
