Try not to use this app. Yes, it's convenient, but you can get ripped off. When you register with the app, you have to link it to a form of payment. After it detects a pattern of parking, like for example for school at GA General Aasembly, it automatically drafted money for parking, even though I was not parked at school that day, I was out sick. Once you register with the app, you can't delete the form of payment, unless you replace it with another form of payment, PayPal or park mobile wallet.
