Film from face-on.

Set your phone 8-10 feet away so GOATY can see your full body, club, and ball.

Face-on view: camera points at your chest, not down the target line.
Full body visible: keep feet, hips, shoulders, hands, club, and ball in frame.
Short clip: one swing, good light, trimmed to about 3 seconds.

Enter your email, then upload your swing. This keeps the results tied to your account so GOATY can coach you after the initial analysis.
