Saves you money!

Everyone who rides the subway knows how annoying it is to have leftover change on a metro card. NYC transit actually plans it that way. They get free money for all the unused metro cards. This app saves you money by telling you exactly how much money to put on the card so that you have a zero balance after riding. This is a must-have app.
