FileMaker is a great toolkit for building an app like fmScoreKeeper. In a few hours I was able to build a multi-sport application that runs on macOS, Windows, and iPhone/iOS.
I got the idea for this app while watching my daughter play a volleyball tournament recently. Because of the way the seats were positioned I couldn’t see the scoreboard behind me…so I needed to track the score for myself. fmScoreKeeper was the answer.
