Golf Swing Analyzer vs SwingDiff

Record a golf swing and the AI traces your skeleton, then turns it into four numbers you can act on: tempo ratio, X-Factor, shoulder turn, and lead elbow at impact. Built for golfers who want honest feedback without an expensive lesson. No subscriptions hidden behind every screen, no fake metrics — just what 2D pose detection can measure reliably. KEY FEATURES Skeleton overlay Google ML Kit pose detection visualizes your body line through the entire swing — address to finish. Four numbers that matter - Tempo ratio (backswing : downswing, pro target 3 : 1) - X-Factor (shoulder vs hip separation, pro 40 to 50 degrees) - Shoulder turn (pro 90 to 100 degrees) - Lead elbow at impact (pro around 160 degrees) Side-by-side compare Star your best swing and put any other swing next to it. Tempo, X-Factor, and shoulder turn deltas appear at a glance. Slow motion and drawing Drop the playback to 0.1x and mark up the frame with line and circle tools to study the position you care about. Chicken Wing detection TPI-style fault watch flags lead-elbow collapse at impact. Per-club analysis Driver, iron, wedge, and putter — pick the club so reference values match what you are practicing. Two camera angles Face-on and Down-the-line are both supported. Right and left handed Switch the calculation logic so the metrics work whichever side you swing from. On-device processing Pose detection runs locally. Your swing video stays on your phone.

See what's off in your swing — through your own skeleton. SwingDiff analyzes your golf swing video on-device, then overlays your skeleton against a reference swing or one of your past swings so you can diff (compare) your way to a more repeatable swing. ON-DEVICE SKELETON ANALYSIS Skeleton extraction with Vision Framework. Address, Top, Impact, and Follow-through are auto-detected as the four key phases — no manual frame scrubbing. 15-POINT AUTO DIAGNOSIS Spine tilt, axis lean at the top, hand position at impact — 15 repeatability-critical points are graded pass / fail with a clear overall score, so you know exactly what to work on next. DIFF (COMPARE) VS. REFERENCE OR PAST SELF Overlay your skeleton on a built-in reference swing, or on a previously analyzed swing of your own. Phase by phase you can see where you drift — and that's where repeatability comes from. PROGRESS TRACKING Every analysis is saved to your history. Watch your score trend over time to see whether your practice is paying off. iPhone Slo-Mo videos (120fps / 240fps) are fully supported. PRIVACY-FIRST Videos, images, and skeleton data never leave your iPhone. No account, no sign-in. Every feature works offline.

Bright outdoor light, a simple background, and enough distance to capture your full body all help detection accuracy. LEFT-HANDED SUPPORT Right- and left-handed swings are both supported.
