How does it work?

With Speedhero you can accurately measure the top speed of football, tennis ball, etc. and easily share the results. The measuring of the top speed is based on advanced sound recognition technology using the microphone of your mobile phone/PC - not the camera. Speedhero uses sophisticated 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 is important to get good impact sounds - so a hard shot against a wall, fence, tarp or other hard surface works well.

1. Choose the sport.
2. Measure from the wall and mark down the shooting point.
3. Place your phone/PC for example on the ground halfway from the wall.
4. After the whistling sound, shoot the ball exactly from the marked point directly against the wall. Speedhero will then measure your top speed*.

*) The Lite version can only measure your average speed.
