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.

Verdict

The call

The clearest difference is rating: Offline Guide at 4.6 against Sentry Mobile's 2.8. Offline Guide also leads on update cadence (every 10 days vs monthly) and ratings volume (1.4K vs 112). Sentry Mobile's advantage is ads (none vs shown). On price, review sentiment, in-app purchases and device support there is nothing between them.
