Swing4Eagle

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
• 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)
