Refill My Metrocard!

[NOTE: THE MTA DOES NOT ALLOW FOR ADDING TO YOUR METROCARD VALUE OVER THE INTERNET. This app tells you how much to add to your Metrocard so you don't have a remainder.]

Don't want to pay $1 for a new metrocard? Having trouble figuring out exactly how much to add to your NYC Subway Metrocard in order to end up with an empty balance after the MTA's bonus?
No problem! Just type in how much your current balance is and you'll get options of how much to add so you don't have a leftover balance! Works quickly and requires no internet connection so it'll work underground; just fire up the app when the MTA machine tells you your balance.
