Welcome to CheetahTS, The Youth Soccer Sub Planner.
This is an small, open source, web app that anyone can use to plan their soccer team's substitution schedule.
The app was made to work well in a browser and on a phone at game-time. Every change is stored in the URL so all you have to do to save the game is bookmark the (very long) url!
You can create a game and start using the tool with the form below, or click here to find the documentation and the source code.
