Application to assist referees in the evaluation of katas. Use the criteria defined by the World Karate Federation - WKF.


This app is a tool to aid in the evaluation of kata using the criteria defined by the World Karate Federation.

The referee or judge will move the white balls that meet each of the criteria to the side of the competitor who presented the best performance. As soon as the ball changes to the athlete's color, the score will be calculated.

If there is a tie in any criterion, the ball should remain white.

If there is a fault during the execution of the kata, the missing button should be clicked. It can be activated according to the number of faults.

After all the criteria are evaluated, click on the results button and a screen with the winner will be displayed.

- in case of a tie the evaluator must choose one of the athletes according to his preference.

To exit the result screen, click the close button in the lower left corner.

To prepare for a next assessment, click the Clear button.
