Hi,
I thought about writing a Squash-App by myself.
But I expect, it would be an easy thing to adopt the Tennis Score Tracker.
In my opinion there were only a few changes with the point counter...

Off course, the greatest thing would be, to release the Tennis-App as a sample within the SDK.
So everyone would be able to create his own Badminton/Squash/Tabletennis/AndSoOn-Application.
Have a nice easter!
