Performance improvements and stability fixes

User reviews

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!

Great App, Just Needs A Minor Fix

WONDERFUL APP! I love love love it! CarPlay Integration works very well and the features are outstanding. ONLY issue is it kills my battery, like bad… even with it plugged in. After this fix though I cannot wait to use it 24/7 when I drive! Keep up the great work.

This app is amazing.

My radar, police and accident crowdsourcing. Seeing my uniden radar detector update on CarPlay is awesome. Recommend wired CarPlay. I was using wireless CarPlay, streaming lossless Apple Music, and using this app all together and it’s definitely hard to charge your phone at the same time sometimes.

Great potential

I will start out by saying flat out that this app is buggy and there’s probably a reason it’s free right now. It doesn’t really seem to hold a connection to my V1G2 like the other apps and it also doesn’t seem to be logging encounters.

That said, it implements speed-based switching between Logic modes and it at least theoretically has GPS autolockouts. These features alone make it JBV1-like and are fairly groundbreaking for a Valentine user on iOS. I really want this to go somewhere, it just isn’t there right now. Seriously has the potential to be the best companion app on iOS for V1G2 users.

Response from developer

Thanks for the feedback. Just wanted to mention that Dukes will always be free. It's a passion project that I work on in my spare time because I enjoy building it and supporting the community. I did some digging into the V1G2 issues you mentioned and found a couple of edge cases that could affect connection stability and encounter logging. Those fixes are included in this week's update, so I'd be interested to hear if things improve for you after updating. If you'd like to help with testing, provide feedback, or follow development, feel free to stop by RDForum: https://www.rdforum.org/ I appreciate you taking the time to leave a review!

Really coming into its own, best app of its type

Long time user of Highway Radar on android, and found my way to this app after being disappointed in the IOS version of HR. The past few updates have turned this into a polished companion app for radar detectors and community sourced alerts, and the CarPlay implementation is far ahead of any of the other apps.
