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 takes your detector to a whole new level of quietness and safety against real threats. • 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. • Option to have the radar detector's alert tones play through the app. ***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.

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

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.

Good R8 companion

It’s worth it

The best.

Incredible adaptability.

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.
