A few things would make this app GREAT.

1. Unable to track stats over a season unless using the website, which requires an expensive subscription fee. Given the already expensive cost of the app, this seems unnecessary.
2. Some uploaded info is incorrect (serve %, for one.)
3. A few crash issues, which hopefully will be addressed soon.
4. Unclear (to me) the difference between "service winner" and "no return" stat options.
5. Need for match types to add flexiblity for sets of less than 6 games (some junior tournaments use this). User set parameters for number of games, sets, and tiebreaker types would be helpful. However, the match types listed cover most adult formats.
6. Needs an upgrade to the interface graphics, but button sizes are perfect the way they are.
7. Needs persistent match preferences to eliminate the need to toggle the same options for every new match.

The actual in-game stat tracking is excellent, and after looking at over a dozen stat apps, this one is the most complete, with the simplest interface to use. Though you can opt to use graphical ball placement (which I find impossible to do in real time when watching a match) you can turn off this function if you dont want/need it.

Summary: biggest negative: seasonal stat tracking cost is prohibitive-- should be included in the price or should allow data storage on device. Biggest positive-- robust stat tracking.

Thanks.
