What's New in R8 Companion

1.40.4

October 10, 2026

Works with CarPlay!! "Feels like a new detector!", -e This is what people are saying after using the Radar Companion™ apps - See what all the fuss is about, try it for yourself! Version 1.40: • Hi-res signal strength meters for both front & rear horns added to the alert banner. See what your detector is seeing, not just the standard bar strength. Front strength shown as a thin line at the top of the banner, rear strength shown at the bottom of the banner. Turn it on by using the option found in both the CarPlay & iPhone menus. • "Active" Banner - K&X noise meter added to top of banner. Enable in the "Map screen" menu under the 'Active Banner' section. • "Active" Banner - MyRadarIQ threat level meter added to bottom of banner. Enable in the "Map screen" menu under the 'Active Banner' section. • Text notification customization. Enable / Disable types of phone & watch text notifications. Found in the R8 Companion's "iPhone" settings menu. • Battery optimizations. Other recent big updates: • SpotLock engine version 2.0.09012026 - latest historical data. • Advanced false assist engine version 3.0.09012026 - latest 6+ years of historical data. • New audio engine handles navigation, speech & detector tones seamlessly with options for output style, voice, speech rate, etc. • Option to include all Detector audio for nav mute tap (kill switch). • CarPlay background-alert controls. • Live Activities for CarPlay, iPhone, Apple Watch. • Alert banner "SignalScope" Shows signal strength over time of the current priority alert. • Alert screen (portrait & landscape views). Option to view classic or new alert screen with a tap of a button. • Ability to turn on/off posted speed limit (US, CA, AU, NZ). • New alert screen banners showing detailed alert, false assist, POI, MyRadarIQ, over speed warnings & other detailed detector status information. • Alternate Route selection with highway, & toll avoidance. • Shows arrival time, distance & trip time remaining. • 'Show traffic' option while navigating. • “Free Drive” (map / no map) alert screen. • MyRadarIQ™ - Threat assessment intelligent system for the radar companion series of apps. A new meter, visible at the top of the main alert screen, will show a graphical representation of the probability of a police presence (Ka or Laser) in the direction of your travel. Using your personal alert data, whenever a high probability exists for an encounter ahead, you will know about it well in advance of facing the actual threat. The meter will go from yellow (low threat), to orange (medium threat), to red (high threat) and flash aa a voice announcement occurs. The meter will also flash red when a Ka or Laser alert is actively being received to help draw attention to the alert. Probabilities are calculated down to the day of the week you are traveling, increasing the accuracy on any given day. If you liked R8 Companion before this release, you are going to LOVE it after! Modify the most popular settings on your R8 radar detector right from the app! See the list below for a complete list of the settings you can modify (more settings coming in future updates). Spread the word, it is only going to get better. If you have an idea / suggestion you would like included in a future update, please visit https://crackedpixel.com/contact-us to let us know. Thanks! Noteworthy info: • Supports both R8 & R8w detectors. • Firmware update notifications via main alert screen. • Option to have the radar detector's alert tones play through the app. • Accessibility option to flash the screen on alert. ***TIP: Setting the main volume for the detector to 0 on the main alert screen and enabling the detector alert tones, will eliminate the brief audio "blips" you would normally hear when a mute command is first sent to the detector. Only potential threats will then trigger audio through your speaker or audio system providing an extremely quiet ride.

Best app for r8w

I didn’t want to spend the 10 dollars to buy this all thinking I wouldn’t use it and it wouldn’t be worth it but I have it running ready to pick up when I get in the car and connect right to my detector. Hands down best 10 dollars spent would never use any other app

Very Good—But Outdated Maps

I like the app very much, but parts of the map view are archaic. Wish you’d replace the current location circle with a directional vehicle/arrow or small car icon that clearly shows the direction of travel, something similar to Apple Maps or Google Maps—especially in Perspective view. Currently, the outdated moving circle reminds me of the old PONG video game from the 70’s.

Finally!

It took a while to find this app, this is what I’ve been dreaming of since I started driving. Dynamic modern maps, integration with the detector, muting of false alerts…I could go on. Please keep up the great work team!

Great! But..

One request, can you get the detector to automatically connect via Bluetooth when CarPlay starts? I have to manually go in and find the r8 each time and I have a lot of Bluetooth devices

Response from developer

Hi JOhnDoeeeee1231, Could you reach out to our support site https://crackedpixel.com/contact-us and help us understand your request? The detector will automatically connect to the app when you turn on the detector. There should be no need to manually go in and do anything. Reach out and let us know the details of your connection problems. Thanks. -Mark

Almost perfect

Great app. I originally gave it 4 stars and said 5 stars if it worked with CarPlay. It does now so I changed it to 5 stars.

FAQ

What does the R8 Companion app do?

The R8 Companion app is designed to enhance the functionality of your Uniden R8 or R8w radar detector. It provides intelligent alerts, advanced muting features, and GPS-based location services to help silence false alerts and improve your driving experience.

What are the key features of the R8 Companion app?

Key features include SpotLocks for location-based false silencing, intelligent voice announcements, a customizable heads-up display (HUD), a proximity meter to better understand signal sources, and advanced muting options for various radar bands. It also allows you to adjust your R8's internal detector settings directly from the app.

How much does the R8 Companion app cost?

The R8 Companion app is a paid application. All future updates to the app are included free of charge for purchasers.

What are the compatibility requirements for the R8 Companion app?

This app requires a Uniden R8 or R8w radar detector with US Version 141 (R8) or 137 (R8w) firmware (or earlier) to function correctly. The app will not work properly without the appropriate firmware installed on your radar detector.

How does the SpotLocks feature work?

SpotLocks enables location-based false silencing. You can enable intelligent location-based learning, and the app will automatically learn and silence false alerts at specific locations. You can also manually 'lock' or 'unlock' locations directly from the main alert screen, and these changes will sync with your R8's built-in auto mute memory.
