Swelta vs SwingDiff

See exactly where your swing drifts from your ideal — measured in joint angles, not opinions. Swelta is a mirror for your swing, not a coach. Register your ideal swing — your own best, or a reference you choose — and Swelta shows, frame by frame, how closely your swing matches it. Just your angles next to your ideal's, so you can see what changed. ◆ No limits, no ads Analyze as many videos as you like — there is no cap, even on the free tier. And there are no ads, anywhere. ◆ One video, measured Record a swing and Apple's on-device Vision detects your skeleton. Swelta computes your joint angles — shoulders, elbows, hips, knees, spine tilt and more — at each phase, and shows your Sync Rate against your ideal. The angles on screen are exactly what the Sync Rate is based on, so the number is never a black box. Free lets you choose Simple or Detailed angle sets; Pro adds Custom, built phase by phase. ◆ Your swing vs your ideal Set your ideal swing, then see the angle gap at Address, Top, Impact and more. You choose which angles to compare — and those are the angles the Sync Rate uses. What you see is what's measured. ◆ Side by side, or overlaid Place two swings next to each other, or overlay them at the skeleton level, with automatic size and position alignment. Read the difference angle by angle. ◆ Real-time mirror Hold a pose in front of the camera and see your Sync Rate live, with per-joint color and the largest gap called out. (A quick cue while you practice — for exact angles, use Video Analysis.) ◆ See it over time Every swing is saved. The Sync Rate trend chart shows how your swings line up with your ideal across days, with milestones and streaks surfaced automatically. ◆ Share Export a skeleton-overlaid clip in one tap, adjust opacity, trim, and post it. A mirror, not a coach — just your angles vs your ideal, so you see exactly what changed, every swing. Swelta shows only what one 2D camera can honestly measure — joint angles and body lines. It does not estimate 3D rotation, clubhead speed or distance, so every number stays something you can see for yourself on screen. On your device: your videos, skeletons and Sync Rates stay on your iPhone.

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.

Position the camera so you appear on the left and the ball on the right of the frame. 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.
