(pensez a faire une traduction anglais-francais)

Speedhero Tennis is the next generation of affordable sports radar in your pocket. With Speedhero Tennis you can accurately measure the top speed of the tennis ball by serving directly against a wall and easily share results.

Choosing the serving distance:

Single player => Settings => Distance. Multiplayer => Play => Settings => Distance. The measurement of top speed is based on advanced sound recogition technology using the microphone of your mobile phone – not the camera.

To measure the top speed: Place your phone, for example, on the ground, halfway from the wall.

Measure from the wall and mark down the serving point (6.4 m / 21.0 ft or 11.9 m / 39.0 ft, depending on your selected distance setting). After the whistling sound serve exactly from the marked point directly against the wall (with no bounces or large shooting angles) and Speedhero will then measure your top speed.

Speedhero uses certain algorithms to detect the first impact sound (your contact with the ball) and the second impact sound (the ball’s impact on the wall). Then, using a tested sport specific flight time dynamic formula and the processing power of your mobile phone, Speedhero instantly calculates the top speed of the ball. It's important to get good impact sounds – so a hard serve against a wall, fence or other hard surface works well.

If you can’t get any readings go to Settings and increase the Sensitivity. If you get incorrect readings or Measuring failed notifications: a) check your Distance; b) eliminate the source of the noise and possible echos; c) decrease Sensitivity; or d) shield the phone against the wind. It is recommended to allow Speedhero to always record sound and/or use multimedia. Refer to your phone manual for how to do this. Have fun!
