Film a forehand, backhand or serve on your phone. RallyMax finds the professional swing closest to yours and shows you exactly where the two split apart.
Ask for early accessHow it works
Prop your phone behind the baseline with the net in view and record a forehand, backhand or serve.
The sound of the ball hitting the strings marks the contact frame. Filmed without sound? Tap the frame yourself.
Your movement from take-back to finish is lined up, moment by moment, against every pro swing of the same shot.
You get the closest pro swing side by side with yours, a 0–100 similarity score and the change to make first.
The comparison set
Each one is cut to a single shot with its contact frame marked, so your swing is always compared from the same moment.
