Begin in a neutral position
Hold your iPhone steadily at a comfortable distance. Make sure your face stays inside the camera view. Relax your expression before following the first prompt.
Follow each prompt
Work through the movements shown in the app. Use expressions that you can repeat comfortably, without moving the phone around to compensate. Pause and reposition if tracking becomes inconsistent.
Check the result in practice
Enter a practice match and try one control at a time. Return to calibration if the controls don’t feel predictable. Better lighting and a stable phone position can help more than exaggerated expressions.
Take a break if you feel uncomfortable. The goal is to find repeatable, comfortable controls.
