Sentry Mobile is the first parking application that actually interacts with your parking meter in real time! Sentry Mobile lets you buy time on an MPS parking meter and the meter instantly updates to show you your remaining time with an icon indicating you paid with the smartphone app! You, as a parker, will see an easy-to-view map of nearby meters including visibility into actual current parking space availability.

You can setup an MPS “stored value” Parker account and pay for parking at any MPS meter. The MPS mobile application allows you to make purchases on Legacy meters and in parking lots where municipalities permit this feature. You no longer have to carry coins or swipe credit cards to pay for parking! The Sentry Mobile application allows you to see your account balance at any time, and to replenish your account balance as needed.

When you pay for your parking and pull into your parking space, the MPS Meter will automatically update with the amount of time you purchased and display a smart phone icon to indicate that your time was purchased via the Sentry Mobile application. No more “guessing” about whether your mobile payment was actually properly applied to your parking spot!

You will receive automatic in-application alerts when your parking session time is running out, and you can see a quick summary of parking sessions you have purchased in the past. The “Where's my car” feature navigates you quickly back to your car.

Technical problems with app

At first I really liked using this app because it was so convenient to use when I don’t have quarters. Now, even if I add time on my phone, it would glitch and say that I have no active sessions left. This happened many times and I have to spend extra money to add time which I already paid for.

faulty app

this app was good at first when i was trying to pay my meter without coins handy, a few months later it doesn’t work at all. I put in $10 in this app that can’t even be used because the app keeps telling me they can’t find my parking meter which is the whole purpose of the app....
