Does iScore utilize the restrictions that Little League places on pitch counts and rest periods based on a players League Age? I could only find a global pitch count warning.

iScore will display the pitch counts for your pitchers, and has the per game pitch count warnings as you noticed, but it does not do anything to stop you from using a pitcher when limits have been reached. That would be up to the league / umpire / coaches to actually enforce something like that. iScore is just used to score what actually happened during the game.

I understand that, however regarding the limits, iScore doesn't take into account the "League Age" as defined by Little League. For a league age 7-8 they are only allowed 50 pitches. But a 9-10 league age pitcher can throw 75. So it's dependent on the age of the pitcher. Then there is a mandatory rest period based on their age and the number of pitches they threw that day. This determines when they are eligible to pitch again. For example a league age 8 pitcher that threw 41 pitches on Monday must have 2 calendar days rest and is not allowed to pitch until Thursday. This would be a fantastic feature to maintain on the app and allow coaches to readily see their eligible pitchers.
