I sincerely hope the app developer and any city infrastructure that uses it get professional mental help and also lose their jobs. ### 1/5 — Rip off!! *2025-07-24, version 9.10* Worst app!! Password site does not work and this needs to be shut down and reported. Please read reviews and fix immediately ### 1/5 — Crashes *2025-07-21, version 9.10* If you were hesitant to invest in a quality app, you could’ve just asked me to build you a reliable one for free. It looks like corners were cut to save money, and unfortunately, the result reflects that. It’s honestly disappointing. ### 1/5 — Very bad app *2025-07-16, version 9.10* Malicious practices. Unethical company ### 1/5 — WORST APP ON APP STORE *2025-07-01* This app is a complete disaster. Absolute trash. I couldn’t log in, couldn’t register, couldn’t even reset my password; just the same useless error message over and over telling me to “contact support.” For what? So they can waste more of my time? Who built this thing? It feels like a high school project that got abandoned halfway through. Nothing works. Zero functionality. And somehow, this still made it onto the App Store? Seriously, what is Apple doing? Did they stop checking apps altogether? The design is straight out of the stone age: clunky, outdated, and painful to use. It looks like it hasn’t been updated since iOS 6. After 10 minutes of trying to get in, I gave up and just left. Total waste of time. This app should’ve never seen the light of day. Avoid it like the plague. ### 1/5 — The longer walk is best *2025-06-27, version 9.10* The other reviews cannot display the amount of disappointment I felt when using their lot and app ### 1/5 — Basically unusable *2025-06-26* This is probably the worst app I’ve ever used. UI is very hard to navigate and select a parking spot. Sometimes the app fails to display how much time I have left. Most days it’s more time efficient to wait in line to pay than use this mobile app ### 1/5 — The worst! *2025-06-11, version 9.10* Cannot even get the app to open. Every time I click on it it shows up then closes. I deleted and reinstalled the app. Same thing. Royal Oak! Get a better system. I paid at the meter. If I get a ticket, I will be furious. ### 1/5 — The absolute worst *2025-06-07, version 9.10* Takes forever to load and faults a lot ### 1/5 — Horrible!!!!!!!!! *2025-05-08, version 9.10* This app is the worst of the worst thing ever. Crashes constantly, you have to load money onto the app. It’s just a bad bad system. Assume someone knew someone to get this contract. I mean it’s bad. Bad!!!! ### 1/5 — DON'T USE THIS APP *2025-04-26, version 9.10* Pay for parking just for a citation later. Not worth, go find parking elsewhere. The city of royal oak needs money so they find anyway to get it. Its actually really sad ### 1/5 — This app causes me to get tickets *2025-04-21, version 9.10* The app refuses to do it’s one job of letting me pay for parking and just force quits whenever I try to do so, resulting in getting a ticket everywhere that uses this ridiculous application ### 1/5 — Useless app, can’t add cards or money *2024-11-13, version 9.5* App never works. Can’t add cards or money. Constantly get tickets becuase of it. And it doesn’t work for anyone else in the area. Scam, just like the city of Royal Oak, Michigan. ### 1/5 — Terrible app *2024-09-20, version 9.3* The app looks like something on an Android phone in 2010 and works as reliably as a 80s General Motors product. Crazy the company would invest so much on the tech on the street and put out such a terrible app. I actively avoid parking anywhere that uses this service. ### 1/5 — terrible app *2024-06-30, version 9.3* Horrible user experience, very buggy. Feels like it was made in 2001, not 2024. ### 1/5 — App won’t even open on iPhone *2024-05-14, version 9.1* Every time I need to use this app for municipal parking, I have to completely delete and reinstall. When I click the app on the home screen, it tries to open but immediately crashes ## Most critical reviews (10 lowest-rated) ### 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. ### 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. ### 1/5 — Complete garbage *2025-09-13, version 9.10* Literally the only way this company stays in business is by defrauding customers into giving them $10 without noting that they don’t have to. They certainly haven’t spent any money on their app since 1995! ## Most praised reviews (10 highest-rated) ### 5/5 — Haters are going to hate *2024-11-02, version 9.5* Now take Apple Pay ### 5/5 — Positive Improvements *2024-04-30* Makes parking fast and is very convenient. This app is always improving! ### 5/5 — Set and Forget *2024-04-29* Concierge added money and don’t have to worry about parking ever, nice feature ### 5/5 — Great parking app *2024-04-26, version 9.1* Easy to use and really like the concierge feature. ### 5/5 — Easy to use! *2024-04-26* Very user-friendly and efficient app! ### 5/5 — Easy and Convenient *2024-04-25* Auto pay works great, I never have to worry about paying or did I buy enough time or getting a ticket. Apple Pay make loading funds into the account fast and easy. Great App! ### 5/5 — Great Update *2024-04-25* The latest update makes the sentry mobile app even better than before. So easy to use and still love the ability to see in real time where the open spaces are to save me time and gas. ### 5/5 — Good Stuff *2024-04-25* I like the flexibility to pay with this app or physically at the meter. Use the autopay feature! It helps a lot. ### 5/5 — Good APP *2024-04-25, version 9.1* Great app. Makes the parking experience seamless with ease of use. ### 5/5 — Seamless! *2024-04-25* User friendly and super helpful. Thankful to have had this during my visit, for parking! Parking made easy. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
