Ball Toss Analysis
Inconsistent toss? Our vision engine tracks the apex and horizontal drift of every toss. We overlay the ideal trajectory (yellow line) against your actual toss (dashed line) to help you find the slot.
Racket Drop & Lag
Deep racket drop creates the whip effect. We measure the angle of your forearm relative to the racket spine at the lowest point. Visual feedback confirms if you are truly letting the racket head drop.
Impact Point
Stop hitting the net. We analyze your contact point height and distance into the court. See exactly where you make contact compared to professional benchmarks.
