## What is Sentry Mobile?

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.

Concierge Autopay Program allows mobile parkers to automatically pay for parking without the need to interact directly with the parking meter or their mobile device.Payments will automatically be applied to your parking session from you MPS account. During your Concierge parking session you will not receive a violation as long as you do not exceed the maximum time allowed or park during “No Parking” hours. You will receive notifications and reminders during your parking session unless you disable them.

### 1/5 — Predatory parking service

*2026-01-06, version 9.12*

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.

### 1/5 — Unable to park and pay

*2026-01-05, version 9.12*

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

### 1/5 — Awful app you’re forced to use

*2026-01-04, version 9.12*

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.

### 1/5 — Horrible Experience

*2025-12-27, version 9.12*

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.

### 2/5 — App doesn’t work

*2025-12-13, version 9.12*

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

### 1/5 — Worst app ever

*2025-11-22, version 9.12*

Can’t reset password, try 5 times, reset. Cant log in. I hate this app and I hate that I have to use it to park.

### 1/5 — Royal oak parking payment

*2025-10-21, version 9.11*

Worst app in history of apps and wasted my time and money

### 1/5 — App is horrible. Parking system is worse.

*2025-10-08, version 9.11*

Absolute worst parking system I’ve ever used in metro Detroit or any other city I’ve visited and the app was garbage to boot. Any city or area considering using this system will likely be sued for fraudulent parking tickets due to how utterly useless Sentry is at monitoring parking and accepting reservations in the app.

### 1/5 — Nonfunctional

*2025-10-02, version 9.11*

I wonder how much this app fleeced the city of Royal Oak for.  Tried to install, uninstalled & reinstalled trying to create an account and just got error messages. Trash.

### 1/5 — Will not accept payment

*2025-09-24*

This app is awful. I tried removing and adding again. Won’t accept credit card without crashing. Won’t accept Apple Pay. Cannot pay for parking. Need to pay directly at meter otherwise doesn’t work.
