What's New in R8 Companion

1.36.8

July 21, 2026

Now 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! This new version is a major overhaul in alert presentation and navigation experience in preparation for future CarPlay integration. New for version 1.36: • CarPlay support - Fullscreen/Dashboard • CarPlay background alerts • Live Activities for CarPlay, iPhone, Apple Watch. Other recent big updates: • New alert banner "SignalScope" Shows signal strength over time of the current priority alert. • Option to hide "Active" banner from free drive dashboard. • Full navigation functionality. • New 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 and other detailed detector status information. • Set detector mode from new alert screen. • Alternate Route selection with highway, and toll avoidance. • Navigation screen shows arrival time, distance & trip time remaining. • 'Show traffic' option while navigating. • 'Recent trip' quick selection. • Nearby points of interest selection. • Quickly switch back from navigation screen to classic alert details screen. • “Free Drive” (map / no map) alert screen when not in navigation mode. • Free Drive without map display option (battery saver). • 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. • Posted speed limit displayed on main alert screen (Currently supported markets: US, CA, AU, NZ). • Customizable low speed muting based on the speed limit. • SpotLock engine version 03012026 - latest historical data. • Advanced false assist engine version 03012026 - latest 5+ years of historical data. • Accessibility option to flash the screen on alert. 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. • New and improved SpotLock 2.0 and Advanced False Assist 3.0. Both data driven systems are updated regularly using 5+ years of historical data. This takes your detector to a whole new level of quietness and safety against real threats. • Option to have the radar detector's alert tones play through the app. The setting is found in the 'Audio Settings' of R8 Companion. ***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.

Amazing App & R8 Tool

This app is simply amazing. This is a perfect tool to complement the R8. The app seems to be updated pretty regularly and it’s amazing how it works. Great app Angela keep up the awesome work, please!

Incredible

At every opportunity, I recommend this app to anyone that can benefit from it. It has been a miracle on my somewhat noisy R8W and has made the auto-lockout function much better. It would be foolish not to have this, and add R/Tach app while you are at it, and you will have the perfect setup. As a bonus, and I just saw this today, apparently CarPlay was added. Thank you for all tour hard work, and smart work, in getting this created and continually making it even better through updates. I never drive without my radar detector, and I never drive without R8 Companion.

Absolutely the BEST

This app works flawlessly, now that you added car play it’s a must have for every owner of a R8 or R8w

Thank you for having the best app out there! My drive just got a lot better

Connected finally

After I updated my r8w I tried connecting and it wouldn’t connect… Until I turned it off and then turned it back on and it connected right away.

Great but needs custom frequency filter

My 2026 CT5 constantly falses at Ka 35.100 one bar strength , probably from the entertainment system. Lowering Ka sensitivity to 80% doesn’t help. Need a low strength Ka frequency filter without merely blocking off an entire Ka segment.

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.
