With a focus on simplicity, R8 Companion™ delivers a powerful boost to your R8’s functionality. Set it, forget it, and drive… It just works! *FEATURING* SpotLocks™!

R8 Companion™ is a feature rich app, designed to give you the most out of your R8 radar detector, while enhancing your driving experience along the way. Featuring intelligent alerts and advanced muting! R8 Companion™ is the COMPLETE solution to enjoying your R8.

The R8 Companion™ app leverages years of optimizations and features from V1 Companion™ (Available separately on the app store for owners of the Valentine One radar locator).

Enhanced GPS location based 'false muting' via SpotLocks™ - All future updates to this app are free to purchasers of R8 Companion™

R8 Companion™'s alerting and muting systems are fully optimized for the R8 platform. Intelligent voice announcements and on-screen visuals will always keep you informed and aware of the situation around you.

NOTE: R8 Companion™ requires a Uniden R8 radar detector with US Version 127 firmware to function correctly.

R8 Companion™ full feature list:
• SpotLocks™ - Location based false silencing has never been this good or easy. Turn on the intelligent location-based learning and let R8 Companion™ do the rest. Or you can manually 'lock' or 'unlock' locations with ease from the main alert screen.
• Ability to set the R8’s internal detector settings ‘Quiet Ride’, 'Limit Speed', 'Rear K Mute' and ‘Units’ from within the app (More detector settings coming in free future upgrades). *Requires US Version 127 firmware.
• SpotLocks™ works seamlessly with your R8’s built in 'auto mute memory' locations. If you create or delete a location from the app it will apply the changes to your R8 at the same time.
• 'Proximity' meter - leverages the high resolution signal strength and direction information provided by the detector to show you a better representation of the signal's source.
• 'K & X falses in area' meter shows you how many possible false alerts exist in the area you are travelling based on the accumulated SpotLock data™.
• 'Custom Phrases' for a given threat's audio announcements.
• High resolution meters for the priority alert (Not limited to the # of bars on the R8 display).
• Customizable heads-up display (HUD).
• HUD displays the priority alert's band, signal strength, frequency, & direction. The HUD is color coded between real threats & muted false signals.
• HUD of the secondary alerts' bands, signal strengths, frequencies, bogey counts & directions.
• Mute rear K & X band signals independently.
• Advanced BSM/CAS/Ka False Muting (Optimized for the R8 platform).
• 'Ghost' muting quiets false alerts when you are stuck traveling near a false emitting vehicle.
• "Passive Mute™"- Quiets the R8 below user set speeds & during weak K & X signals.
• Bogey count display showing total number of threats.
• Vehicle speed (MPH or KMH) display. Speed is color coded for each alert type.
• Mute status with the ability to manually mute/unmute alerts as you need.
• Detailed & intelligent voice announcements of direction, band, frequency, strength, number of alerts, occurrences of mixed signals and more.
• Automatic muting of Ka, K, and X bands ('Time before mute' set for each band).
• 'Reduce Speed' notification for user set speed.
• ‘Urgency Alerts™’ - Unmutes growing threats & announces these alerts via voice & notifications.
• ‘Alert History’ - View your past alerts with detailed information about each encounter.
• Compass heading.
• Imperial/metric units.
• Detailed trip summary at the end of your ride including duration, distance, alerts, muting stats, battery, and more.
• Automatic connection via Bluetooth.
• iPhone & Apple Watch notifications of direction, band, & frequency of each alert.

Feels like a new detector.

I got this app when I saw Vortex mention it. The options this app provides are excellent. It’s like having a new detector. The app had blocked most BSM from setting off my detector. Threats from KA seem to be better too. I’m not sure why that is but I’m not complaining. If you have an R8, I highly recommend you get this app.

Great Start

Great start to this app. Really enjoying the ride. Makes everything more quiet and make the R8 feel like a new detector! I can’t wait to have some live activity’s and time sensitive notifications built in, so this can run in the background.

R8 Heaven

So pleased to have the ability to customize my R8. Definitely looking forward to updates and new features like a home screen widget and/or a carplay app. Thanks for supporting iOS too.
