Golf Head Lock is a focused motion-coaching tool that uses your AirPods to help you stabilize head movement and build a more consistent golf swing. It delivers clear, real-time feedback on three key movement dimensions so you can practice with purpose.

• AirPods-powered motion tracking
• Connect your AirPods, tap Refresh, and stream live motion data directly into the app.
• Visual connection status and readiness confirmation keep setup simple.

• Three core stability metrics
• Stillness (Gyro Z): Measures rotational movement (turning left/right). Ideal for monitoring head rotation during setup and takeaway.
• Sway (Accel XY): Tracks side-to-side movement by analyzing horizontal acceleration magnitude. Helps reduce lateral drift.
• Bobbing (Accel Z): Detects up/down movement to minimize vertical bounce or nodding.

• Real-time thresholds with color feedback
• Each metric shows a live value and a target threshold.
• Green indicates you’re within target; red signals excess movement.
• Designed for quick at-a-glance decisions during practice.

• Adaptive coaching by skill level
• Select Pro, Amateur, or Beginner to adjust sensitivity and thresholds.
• Start with more forgiving targets and tighten as your consistency improves.

• Stillness baseline and smart stabilization
• The app automatically detects periods of stillness and resets baselines.
• During steady moments, values pin to zero for a clean, calm visual state.
• When movement resumes, the display updates instantly with meaningful deltas.

• Smooth, readable metrics
• Low-pass filtering reduces jitter on rotational movement for a stable display.
• Clear typography and large numeric readouts make values easy to read from a distance.

• Raw data for deeper insight
• View gyroscope (Z-axis) and accelerometer (X/Y/Z) values in real time.
• Use raw numbers to validate your setup or fine-tune sensitivity.

• Simple controls for practice flow
• Start/Stop streaming with one tap.
• Prominent Refresh button to re-establish connection quickly.

Golf Head Lock helps you eliminate unnecessary head movement, tighten your setup, and groove a repeatable swing. Whether you’re working on pre-shot routine, takeaway stability, or impact consistency, the app gives you immediate, actionable feedback to train smarter.
