Swing4Eagle: AI Golf Coach

Dan Huang

About this app

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.

Just record. The AI does the rest: it finds every key position, grades your mechanics, and gives coaching tips. No clipping, no labeling, no signup. Your videos never leave your phone.

WHAT IT ANALYZES
Record or import a swing from face-on or down-the-line. Swing4Eagle automatically finds the 8 key moments of your swing and grades the mechanics at each — no manual frame selection.

FACE-ON CHECKS
• Stance width and lead shoulder tilt at address (driver setup)
• Hip sway through the backswing, top, and impact
• Posture and spine tilt
• Shoulder tilt and 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 A PRO
Tap any analysis to overlay a tour-pro reference — driver pros for driver swings, iron pros for irons. See your swing, then theirs, side by side.

FIX YOUR SLICE OR HOOK
Whether you're battling a slice, a hook, or just chasing more consistent tempo and form, Swing4Eagle turns your own video into a clear, position-by-position review.

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 gallery
3. AI finds the 8 key 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

For long clips, trim to just your swing for faster results — or mark the 8 positions by hand if you want full control.

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 players fixing fundamentals to single-digit handicaps chasing the next two strokes. Supports right- and left-handed golfers.
