Swing4Eagle

Just record. AI does the rest — finds every key position, grades your mechanics, and gives pro coaching tips. No clipping or labeling. Free. On-device.

Why does the pro's swing look smooth, and yours doesn't? Swing4Eagle's on-device AI breaks down your swing video frame-by-frame — from any angle — and shows you exactly what to fix.

Free. No signup. Your videos never leave your phone.

WHAT IT ANALYZES Record or import a swing video from face-on or down-the-line. Swing4Eagle automatically finds the 8 key moments of your swing and grades the mechanics at each.

FACE-ON CHECKS • Stance width and lead shoulder tilt at address (driver setup) • Hip sway through the backswing, top of swing, and impact • Posture and spine tilt • Shoulder tilt at mid-downswing • Lag angle at mid-downswing • Knee extension, head movement, and reversed-K shape at impact

DOWN-THE-LINE CHECKS (NEW) • Address hand position (driver- or iron-specific) • Trail hand vs trail hip at toe-up • Swing depth and shoulders vs lead arm at the top • Hands vs chest at mid-down • Trail-arm bend at impact
• Spine tilt maintenance through the whole swing • Early extension check (address to impact)

COMPARE TO PRO Tap any analysis to overlay a tour-pro reference — driver pros for driver swings, iron pros for irons. See your swing, then theirs.
