Balancing play times and

simplifying rotations

for coaches of youth sports.

Who's On

One of the most challenging tasks for a sports coach is trying to balance play times while strategically assigning positions during a game. Who's On apps have been designed to make your life easier.

Each Who's On app remembers how long each child has played and in what positions so you don't have to. This allows you to focus on the game and make more informed rotation choices.

Using simple drag and drop of player icons, you indicate your position assignments. Who's On does the job of tracking play times and positions for each of your players so you don't have to. Remembering where Adam last played or how long Julie has been on the field will no longer be a problem.

We've design Who's On apps to be intuitive and robust. If you're interested, please watch the short videos listed below.
