I made an app that allows you to track the score of up to 20 players of two teams. You can choose all names yourself. Plus and minus points can be tracked and undo is also possible. As an extra, the app counts your steps and calculates the distance.
You can test it here
Don’t worry, I added an english translation (I need some English screenshots btw). Please post all issues with this app here.
