In short
ParkChicago is a free Android app from PassportParking Inc. It is a great way to have in pocket.
Highlights
Super convenient to have in your pocket
Stores frequently required fields easiest way to park in Chicago
Great app that makes it easy to park in Chicago
I love using this app
This is the greatness of cloud services and internet
Saves me having to walk outside again to pay at the kiosk
Helps to avoid running out to feed the meter while out and about
Allows reminder to feed the meter
Allows you to add money without actually going to the car
Best app in the winter
There's no way to use this app for a small handful of parking spots
Its only for the millionaires not the for the normal people
Avoid the walk to feed the meter
It still asks me to add more money
What's up with the additional price gouging
The minimum amount for your account seems like a rip off
They're robbing more money for the parking
It still wont process the transaction
That's way too slow and old school
Never get another ticket for an expired meter again
