How does it work?

With Speedhero you can accurately measure the top speed of football, hockey puck, 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. 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.
