Good but a couple of issues need addressing

I have used this app to track two matches now. Overall, it is quite good and I recommend it although I feel that it is a little expensive for the current feature set. That said, we have already found the statistics to be useful for helping our son develop a better understanding of his game. The things that I like:
1. The statistics display and email capability are quite nice.
2. The user interface if fairly intuitive with easy to read and hit buttons
3. The ability to time the game and points is nice.

There are, however, a couple of issues that I would recommend be addressed in future updates.
1. The biggie is that there is no undo so there is no way to correct a mistake and it can get you completely messed up and out-of-sync with the match. This is especially important for tracking junior players. While I marked the outcome of points correctly, the players on occasion make incorrect calls or even get the game score confused and there is no way that I found to fix this in the current app. Likewise, on a couple of occasions I incorrectly scored a point for the wrong player and then couldnt fix it.
2. Related to #1 is the fact that there is an annoying popup to confirm the outcome of each point. This is needed right now because there is no way to fix things if you make a mistake so you need to think twice before confirming the popup. Once there is an "undo" feature, this popup confirmation box should be removed as it will greatly simplify and speed entry.
3. Right now, there is no way to record a service winner. Instead, you have to mark it as a forced error which is okay but I would rather know that it was a service winner.
4. There currently is a way to edit the game score in a given set but there is no way to correct the point score in a game. This would be really nice, again, especially for a junior match where they sometimes score points incorrectly but you still want to capture the correct shot statistics.
5. There should be a "pause" button to stop the game clock if needed.
6. The statistics should also record the time per set and, ideally, the time that each player was serving.
7. You might consider adding the capability to record whether a volley winner/error is forehand or backhand.
8. Another bigger issue is that there are only a limited number of scoring rules available and they dont currently fit well with junior tournament. I would recommend that you either add a significant number of additional rules or allow the user to build a custom rule. For example, the matches that I tracked today were two sets (with 7pt tie-breaks for each) and a 10pt tie-break in lieu of a third set. There should also be the option for no-ad scoring.

Hopefully these suggestions will be helpful. Great app, and again recommended.
