Swing4Eagle

AI Golf Swing Analyzer & Coach

Free

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) 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. HOW IT WORKS 1. Pick your handedness, club (driver or iron), and camera angle (Face-On, Down-the-Line, or Auto) 2. Record live or import from your photo library 3. AI finds the 8 key swing positions — address, takeaway, top, mid-down, impact, follow-through, and more 4. See annotated frames with pose overlay and metric callouts 5. Tap "Compare to Pro" on any screen for a side-by-side reference WHY ON-DEVICE No cloud upload. No account. No data collection. Works offline at the range — even with no signal. Built for serious improvement, from weekend hackers fixing fundamentals to single-digit handicaps chasing the next 2 strokes. Supports right- and left-handed golfers.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

• New down-the-line checks: torso lean at address, shoulder tilt at the top, and a "did the club shallow?" check at mid-down. • Fix events yourself: a new "Mark" button on the results screen lets you set the 8 key swing frames by hand when auto-detection isn't quite right. • More reliable swing detection on faster and lower-frame-rate videos, with a heads-up before analysis if a clip is below 30 fps. • Left-handed down-the-line improvements, refreshed pro reference clips, and various accuracy and display fixes.
