Not sure if everyone already knows about this iPhone App (and maybe Android, I don't know). It was free. It is just called Disney Gift Card. You can enter in all your Disney gift cards. As you use them, it will update the current balances when you refresh. It also shows where and when each was used. It is particularly useful when you have multiple gift cards. I have a bunch because I got many $50 ones during the Stop & Shop gift card promotion (where you get back a $15 Catalina coupon for every $50 gift card you purchase).
