Predatory parking service

Parked here because all other parking near movie theatre was taken. Intentionally does not let you renew parking beyond a time limit that is less than the length of a movie. As a result, forced to pay a citation.

Unable to park and pay

App doesn’t work. Entered the parking spot number on the meter but app could not find it.

Awful app you’re forced to use

The meters I’m parked at aren’t even listed in the app, so I guess I’m gonna get a citation. Thanks for nothing! Perhaps actually developing your app would benefit the people who have no choice but to use it.

Horrible Experience

Not sure how you losers won the contract with the city of Royal Oak, Michigan. This is the worst and most predatory parking system I’ve ever had the displeasure of using. Glad to see you going away. It amazes me how things like this can even happen.

App doesn’t work

Every time I try to use this app pages don’t load

FAQ

What does Sentry Mobile do?

Sentry Mobile is a parking application that allows you to interact with parking meters in real-time. You can buy time on an MPS parking meter directly from your smartphone, and the meter will update instantly to reflect your remaining time and payment method.

How does Sentry Mobile make parking payments easier?

It eliminates the need to carry coins or swipe credit cards at parking meters. You can set up a stored value Parker account, pay for parking at eligible meters and lots, and easily replenish your account balance through the app.

Is Sentry Mobile free to use?

The application itself is free to download and use. However, you will be making in-app purchases to pay for your parking time, which is a cost associated with using the parking services.

What features help me manage my parking sessions?

The app provides automatic in-application alerts when your parking session time is running out. You can also view a summary of past parking sessions and use the "Where's my car" feature to navigate back to your vehicle.

What is the Concierge Autopay Program?

The Concierge Autopay Program allows for automatic parking payments without direct interaction with the meter or your device. Payments are applied from your MPS account, and you won't receive a violation as long as you adhere to time limits and parking restrictions.
