iRewardChart is an app for parents to track your children's good behavior for reward later.
And really, that's all there is to it. You can define points for certain activities, more, less, with objectives, bonuses, and so on.
In other words, you create a formal credit / debit system to reward kids for "good behavior", no more "mommy forgot" and "you promised!"
Not a bad idea... if you have kids ad they are not behaving.
