There's no one "right" swing. You decide what your ideal is - a pro, a friend, your own best. We line up both swings and show the real gap. Unlimited analyses, no ads. 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. No account, no login. 【Pro】 • Build a custom angle set per phase + derived metrics (Free: choose Simple or Detailed) • Unlimited real-time use (Free: 5 min/day) • 5 round observation cards and first/second-half comparison (OB/penalty roundup is free) • Best swing per club • Watermark-free video and summary sharing • Up to 5 ideal swings Terms of Use (EULA): https://past-dandelion-e58.notion.site/Terms-of-Service-Swelta-367372952c8580e498a1c6304391b375 Privacy Policy: https://past-dandelion-e58.notion.site/Privacy-Policy-Swelta-367372952c8580cca79cf66d2bed8171
