What Is This App?
Dukes Radar is a driving companion app for your iPhone. It connects wirelessly to a radar detector and displays alerts on your phone with detailed information like signal direction, strength, and distance.
Even without a detector, the app shows crowd-sourced police reports (real-time sightings reported by other drivers), speed camera and red light camera locations, community hazard alerts, and turn-by-turn navigation — all on a single map. Think of it as a smarter, more visual way to stay aware of what’s ahead on the road.
Quick Start
Get up and running in under five minutes.
Pair Your Detector
To connect your radar detector to the app, open Bluetooth & Detector settings and tap Scan. Your phone will search for nearby detectors over Bluetooth (a short-range wireless connection). Select your detector from the list once it appears.
Supported detectors: Uniden R4, R4w, R8, R8w, R9, R9w and Valentine One Gen2 (V1G2).
Don’t have a detector? No problem — enable Standalone Mode to use the app without one. You’ll still get police reports, camera alerts, navigation, and everything else.
Set Your Units
Go to Settings → General and pick your preferred units: KM/H (kilometers per hour) or MPH (miles per hour) for speed, and KM or Miles for distance. Every screen in the app will use the units you choose.
Download Police Enforcement Overlays
Go to Settings → Map & Overlays and download the overlay packages for your region. These paint a heatmap (a colored layer) directly onto your map showing areas where police have historically been reported setting up speed traps — warmer colors like red and orange mean more activity. Packages are available for all of Canada, the United States, Australia, and New Zealand.
Configure Alerts
Visit Settings → Alerts & Sounds to choose your on-screen alert size and colors. “Bands” refer to the different radio frequencies that police radar guns use (like K, Ka, and X) — each can have its own color so you can tell them apart at a glance. Enable Voice Alerts for hands-free spoken announcements. For camera warnings, go to Settings → Safety Alerts and make sure Speed Camera Alerts and Red Light Camera Alerts are turned on.
Drive
Keep Screen On enabled, mount your phone where you can see it, and hit the road. The app takes care of the rest: it automatically reconnects to your detector, shows you alerts as they happen, and quietly memorizes locations with harmless signals (like automatic store doors that trigger false alerts) so it stops warning you about them over time.
