Club speed isn’t made by your arms — it’s passed up the chain: ground, hips, torso, arms, club. This tool watches your downswing and checks whether your chain fires in order.
The longest hitters don’t swing the hardest — they sequence better. The hips fire first, the torso whips behind them, the arms come along, and the club arrives last and fastest. Fire out of order — shoulders first, the classic over-the-top move — and you leak speed and cut across the ball.
Upload one swing. The AI pose-tracks your body and answers three things: how fast is your downswing, what’s your tempo, and the big one — do your hips move before your shoulders?
“Force comes from the order, not the effort.”
Phone vertical, propped on your bag, facing your chest. Whole body in frame, head to feet, about 8–10 feet away. Bright light helps.
Keep it short — 4 to 8 seconds, one swing. The tool needs to clearly see your hips and shoulders through the transition.
One swing. Face-on. Whole body.
Everything happens on your device — the video is never uploaded anywhere, and nothing is saved.
A 4× slow-mo clip makes your downswing look four times longer than it was. Pick how you shot it.
Force Score reads your sequence. For the full skeleton teardown — backswing time and hip drop — run the Swing X-Ray. If your chain fires out of order, the fix usually starts with tempo: Slot Score.
