It would be great if there was a practice mode so that I could track pitching sessions which documented the number of pitches thrown, location, ball/strike, and pitch type for each player with the date. This data would be great to track a player's progress all season. It could be accessible on the stats page. The players we coach are just learning to pitch and watching trends would be powerful. Data like this could also alert you when a pitcher may be getting too much work on a long season and help to keep arms fresh and prevent injury.
New user. Love the app so far.

We have plans to create a separate pitch tracking application in the future that could be used for this type of thing, but iScore Baseball itself is focused on scoring games.
