Pretty rad, if you live downtown or ever use a parking meter this FREE app is perfect! It's called Parking Time.
You put in how long you have and it counts down for you, you also can have it give you a 5, 10, or how ever long you chose minute warning. Other dope features...notes, pin point your parking spot, it will even give you directions back to your spot with "find my car"!
Hope you love it as much as I do.
