SmarTrip® is a free Android app developed by the Washington Metropolitan Area Transit Authority that allows you to pay for public transit in the Washington, DC area. It is the perfect solution for both new riders and regular commuters who want a safer and more convenient way to pay.

The app offers a lot of features for its users. You can add a new SmarTrip® card to Google Pay for a tap-and-go experience on Metro. If you already have a SmarTrip® card, you can move it to Google Pay without adding a new one. SmarTrip® also allows you to pay for any rail or bus trip using your Android phone, anywhere SmarTrip® is accepted. You can check your balance, add money, or set up Auto Reload, which means you'll never have to use a fare vending machine again. You can also manage your account, check SmartBenefits, or register a card. Additionally, you can buy money-saving unlimited transit passes anywhere and anytime, and pay for parking at any Metro-operated facility.
