Do you find that tennis scoring apps usually require your full concentration on every point in order to get good statistics? Stop you watching the game and applauding the good plays? Leave you stressed when you make an error? If so, then TennisTrend is the app for you!
It has four simple screens, one to enter (or recall/delete) the match details, one to keep the game score and some useful details by simple taps, one to see graphically (and uniquely) how the state of play is changing over the match, and one to give some key performance statistics. All the data is preserved locally for each match scored, so you can always look back.
As a tennis father myself, I developed the app after trying to use the sophisticated offerings around, and finding them too intimidating. My daughter also didn't want to know the fine details - she knew if and how she got it right or wrong. But the graphical record and the basic statistics helped her recall the details later when ready to assess her performance. And helped her prepare to avoid those problems in future.
Give it a try!
