Questions, answered straight

Film one swing with your phone — face-on or down-the-line, normal speed, whole body in frame — and upload it to AnchorStance. In about two minutes it rebuilds your body in interactive 3D, tracks your club, and measures 20+ swing metrics against tour ranges. No sensors, no launch monitor, no second camera.

Across setup, backswing, transition, impact and tempo: spine angle, X-factor (shoulder–hip separation), hip sway, lead knee angle, stance width, early extension, swing tempo (backswing-to-downswing ratio) and more. Every metric is shown against its ideal range and labelled measured or estimated, so you always know how much to trust a number.

No. AnchorStance works from a single ordinary phone video. Computer vision reconstructs your body in 3D and tracks the club directly from the footage — the same clip you would already film at the range.

Film at normal speed (not slow motion), in good light, with your whole body and club in frame from address to finish. Face-on (camera in front, square to your chest) works best; down-the-line (camera behind, looking at the target) is also supported. A tripod or a friend holding the phone at hip height is ideal.

Early extension is when your hips move toward the ball on the downswing instead of rotating, forcing your upper body to stand up through impact — a top cause of blocks and hooks. AnchorStance detects it automatically, shows you the exact frames, and attaches drills like the chair drill to your Fix List so you can retire it with clean swings.

Yes — your first Premium 3D swing analysis is free, no card required. After that you can subscribe ($40/month or $400/year for 100 analyses a month) or pay as you go with credits at $2 per swing.

A 0–100 score never told anyone how to swing better, so AnchorStance does not show one. Instead, every measurement sits against its ideal range — in range, close, or needs work — and the analysis leads with the one fix that matters most. Progress is earned as consistency Levels across many swings, not one lucky number.

Yes. You set your handedness once at onboarding (changeable in Settings) and every metric, camera angle and drill is labelled for your lead and trail side correctly.
