This is an app I created for use in a tennis club, and I uploaded it because it's surprisingly useful.
There are no complicated settings such as names or fixed pairs, it is a tool that simply determines the number of players, determines the order, and plays a doubles game according to the progress table.
Feature 1: To determine the order, when you touch the screen, a random number for the number of people is displayed, and it is displayed upside down so that the person who touched it can easily see it.
Feature 2: You can check the progress on the progress table and check the progress. Furthermore, as long as you do not press the "back" button, even if you change the app screen or end the interruption, the progress table and check status will be displayed when you restart the app. Display again.
Feature 3 Progress table A is data created by the same person so that the number of games is the same without continuing as much as possible.It is not a random number. Therefore, multiple people can use the app to manage progress together.
Feature 4: Progress table B is calculated so that each player plays the same number of games as possible. In some cases, the same person may come in succession or the same pair may form. Also, the number of matches will increase depending on the number of participants, so please choose the matches according to the time.
*The increase or decrease in the number of people during the process is different between Progression Table A and Progression Table B. Progression Table A simply increases or decreases, so the pairs may be the same. Please change or replace the pairs and proceed.
