I Head Coach a baseball team and 1 of 2 possible scorerkeepers will be using iscore on their personal ipads. Do each of them need to purchase the iscore app separately on each device in order to load the software? Or can we just purchase it once and share?

If the two devices use the same iTunes account, then only one purchase is required. If they are separate iTunes accounts, then they would each need to purchase iScore.
