Measure the tennis serve speed with the help of high-resolution audio recording with 48,000 samples per second! You don't need to play touch screen reaction heroes like in other apps - let your phone or tablet determine the flight time!
Two parameters are required to determine the speed: distance and time. Set the distance by selecting the ball impact position on the virtual tennis court. The time is automatically determined by the application by the distance calculation with millisecond precision between two audio pulses - ball contact with the tennis racket and ball contact with the ground.
The application displays three determined speed values:
1) very accurately measured average speed;
2) approximate starting speed (as in professional tournaments), depending on the impact type (FREE version only with the kick-serve type);
3) approximate pre-impact speed of the ball.
More information on application usage you can find in the integrated help.
Have fun with your tennis serve measurements!
