The idea for this App originated from the Tennis Warehouse Community where more than 750 people up voted for this App to be made.

This App has been created with dedication and passion to improve the most powerful skill a tennis player can have: ‘the serve’. It uses advanced algorithms to calculate the initial speed (ISS), which corresponds to the speed shown on TV. The calculation is based on the position from where the ball was hit ‘till its landing location inside the service box. Holding in account the player’s height and most important the travel time of the ball. Taking advantage of the iPhone’s great camera, this App allows you to record your serve at 240 FPS (frames per second) that provides the best precision!

Using a simple 4 step intuitive interface, which includes the graphical representation of the court with a moving scale that will further enhance the precision of data entry, you can calculate the serve speed within seconds.

There’s a free feature in this app that allows you to save your serve videos including the speed and date. This will help you to keep track of your serve’s history, making it easier to review and compare them to your opponents.

This app has been updated by Apple to use the latest Apple signing certificate.

!- IMPORTANT NOTE => there is a problem with the app on the iphone 7 and 8: the app does not allow you to select and calculate videos in your camera roll. However you can instantly record and calculate serves! Due to sickness I currently cannot fix this, but I will come with an update later this year. :( -!
-----------
Improved accuracy by adding functionality that allows you to select the service box from the video frame, which makes it very easy to determine the exact bounce position of the ball!
