Paying for parking without having to involve my phone or credit card is pretty nice.

My pants don't have big enough pockets to carry enough change given the parking rates in California.

I like paying for parking with my phone. It lets me extend when the time is about to run out and cancel the remainder when I leave early.

Does cancelling refund the extra to your card? I assumed most systems would just eat it so I may as well leave it for the next guy.

Canceling refunds the extra amount to my balance. The app only charges the balance once a month.

You can't leave it for the next guy, because it's not a parking spot that's paid for. Instead, you pay to park a certain car in any spot in a larger parking zone.
