Tennis
Measure your serve speed and racket swing speed with your iPhone or Apple Watch. Arm Speed Analyzer gives you instant speed data so you can train smarter and hit harder.
Track Your Serve Speed
The serve is the most important shot in tennis. Arm Speed Analyzer measures your arm speed and acceleration through the service motion, so you can see exactly how fast you're swinging.
Track speed across practice sessions to build a faster, more consistent serve. See your max speed after every attempt and watch your progress over time.
Improve Your Groundstrokes
It's not just about serves. Track your forehand and backhand swing speed to understand the power behind your groundstrokes. Compare different grips, stances, and techniques with real data.
Consistency wins matches. Use your speed history to see how repeatable your swing really is and identify where you can gain an edge.
