ProTracker Tennis

I bought and tried most of the tennis stars apps before settling on ProTracker Tennis. Be sure to check out the documentation on the developer's website to really understand how thorough and powerful the App is, and how you can easily customize the level of detail you wish to capture.

Very impressed with this iPad/iPhone app and its "sister" PC app (which I think you'll need if you want a serious reporting/distribution capability). Yes, the two apps are pricey, but they have been obviously carefully thought through and everyone is amazed at how much quality data (and analysis) I can accumulate in a given match. And since most of the matches I'm covering are doubles, this pretty much eliminates the competition. Again, this program overcomes most of the complexity of catching all the important elements of a doubles match and attributing appropriate characteristics to teams and individuals as appropriate - again, very well thought out. Although fairly intuitive, this app will require a little bit of a learning curve, and some practice to keep up with the play and gather accurate data, but it gives you as much help as it can. After a little time practicing on, say, some televised matches, and then a few practice "live" matches to get the flow, you'll be busy but you can collect the data fairly comfortably. Finally, Eric (the developer) is very responsive and very helpful in answering questions. He will clearly not leave you high and dry if you're having a problem or needing a question answered. Kudo's!
