The ONE

This is the RD app you’ve been looking for. The threat analysis displayed as a risk % is genius. It is HIGHLY customizable and the menus take a long time to learn. Skip that: have your preferred AI research all the settings off the developer’s website, then advise you on how to set it up for YOUR situation.

Quick Custom Feeds Broken

The quick setup of custom feeds is broken. Save button does not work - stays gray. Developer is completely unresponsive. I get that bugs can exist, but when a developer ignores people who take the time to report them, well then the 1-star is well earned.

Response from developer

If the Save button is greyed out, it usually means some of the information entered isn’t valid or a required field hasn’t been completed. I was also away on holidays for the past two weeks, so I apologize if I missed your message. I’m definitely not ignoring anyone, and I do my best to respond to everyone who reaches out. Feel free to email me directly and I’ll be happy to help you get your custom feed set up and working properly!

Notifications

I absolutely love this app, especially for my radar detectors to have them displayed through CarPlay. The only thing that would make it 10 times better is for example a KA band to pop up as a notification in CarPlay similar to how the escort radar detector app works if I’m on the music screen, it’ll pop up a notification and sound for the band frequency the only way I can see the band free frequency is if I’m on the map itself but overall this app is fantastic especially to connect radar detectors

Response from developer

Thanks for the review! Dukes does support background CarPlay radar alerts while using other CarPlay apps, including band and frequency notifications. Please check that CarPlay Background Alerts is enabled in Dukes under the CarPlay settings. If it is already enabled and alerts still aren’t appearing, please reach out through the app so I can help troubleshoot it.

Liking this new RD app

I am always interested in a new app to help my radar detector become a smarter, easier and quieter device to get along with. While i had some stumbling blocks with Dukes on day 1, I think I have gotten over those and making progress. And so far. I’m loving it. The addition of CarPlay connectivity is new and welcome. Im anxious to get more time on this thing and continue ti learn more, and watch the changes as updates and upgrades are made over time. Well done!
