Ever come across a situation when you need to randomly select a person from a group to pit against another randomly selected person from another group? Or a random team from one group against another random team from another group?
Use case include if you are a teacher and you want to conduct some simple classroom games, you use this app to pair off each student from two groups. If you conduct your own local competition like soccer, you use this app to pair off each team among two groups. And many more possible uses as long as you need to random select one member from one group against a random selected member from the other group.
Granted most can be achieved by drawing lots but the app will be faster when you want to re-randomize again in comparison to the draw lots mechanism whenever we want to re-draw again.
The application support English, Simplified Chinese, Traditional Chinese display.
