xCaddie turns your phone camera into a 3D biomechanics lab and a Strokes Gained engine — measured on-device, and clear about what the data can and cannot say.
Phone, face-on, on a chair or a bag. One swing is enough — or several in a row. Normal 30/60 fps is fine; no slow-motion, no tripod.
The single root cause behind your fault, and at most two concrete drills with video. Never more than you can work on.
Film again and we tell you whether you actually improved — on real numbers, above the noise.
3D pose, not flat video. A computer-vision model estimates 3D world landmarks for every frame of your swing, entirely on your device. We treat those joints as measurement points — and derive posture, spine angle, alignment, sway and your real tempo ratio directly from the geometry.
A swing clock from P1 to P10. A rotation-fused phase detector reads signed shoulder rotation from the 3D landmarks and uses it as the swing's internal clock, segmenting motion into its true positions. Feedback lands on the exact frame — address, top, impact, finish — where it actually belongs.
Strokes Gained, computed exactly. On-course GPS shot tracking on a real OpenStreetMap course map drives a Broadie-exact, additive Strokes Gained model straight from the 2011 research, and learns your per-club carry and roll over time. Nothing is guessed in the cloud.
Built by golf-tech experts and AI + computer-vision engineers — instruction knowledge, paired with the engineering to measure it.
3D world landmarks per frame drive posture, spine, alignment, sway and tempo — measured, not guessed from a silhouette.
A rotation-fused detector segments your swing so each cue lands on the exact frame it belongs to.
GPS shot tracking on a real course map feeds a Broadie-exact, additive model — off the tee, approach, around the green, putting.
Your per-club carry and roll, learned from your own GPS rounds — your yardages, not a generic chart.
One focus, the drills for it, and next time we re-test that exact fault. You advance only when you've earned it.

No. Just your phone. Film face-on, the phone steady at waist height, and that's it. Normal 30/60 fps is fine — no slow-motion, no tripod.
Precise on what a camera can truly measure — 3D body motion, posture, spine, alignment, turn, tempo, early extension, sway — and plain about what it can't. Clubhead speed, ball speed, spin and club-path degrees need a launch monitor, and we won't pretend to be one. We never hand you a number we didn't earn.
Yes. The analysis is identical. The level — beginner to pro — changes only how the read is explained, never the analysis underneath. We don't inflate a score to flatter anyone.
Yes. Your swing video never leaves your device for analysis. EXIF and GPS are stripped on upload, the raw video is deleted shortly after processing, and a swing is shared only if you create a link — private and revocable. No public feed.
Anytime, from the app. No commitment.
