R4 Companion Updates and Release Notes
"Feels like a new detector!", -e This is what people are saying after using R4 Companion™ - See what all the fuss is about, try it for yourself!
Version 1.16 Updates:
• New detector settings menu.
• Instantly see your changes when modifying detector settings.
• More reliable BT connections.
• Compiled with latest iOS 26.1 XCode.
Other recent big updates:
• 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 on and off and a voice announcement will occur. 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 actual day of the week you are traveling, increasing the accuracy on any given day.
• Latest historical BSM/CAS data for better protection against K falsing.
• New accessibility option flashes the screen when an alert occurs.
• New iOS 26 Liquid Glass UI elements.
• New light, dark, & tinted icons.
• Improved speed calculations providing better accuracy and smoothing.
• Updated NZ Firmware detection.
• Additional fix for "Spot Lock" voice announcement ducking audio not returning to normal volume.
If you liked R4 Companion before this release, you are going to LOVE it after! Modify settings on your R4 radar detector right from the app! 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!
Other noteworthy updates:
• First major update to "SpotLock" system (location based lockouts) since its release.
• New and improved SpotLock 2.0 and Advanced False Assist 3.0. Both data driven systems have been updated using 5 years of historical data. This takes your detector to a whole new level of quietness and safety against real threats.
• Added ability to backup/restore all, or just backup SpotLocks, POI, and Ka and Laser Alerts individually.
• Added the option to have the radar detector's alert tones play through the app.
• The app will read your detector's settings for each signal type's alert tone (1-12) and use the associated alert tone within the app for alerts.
***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.
• New 'GPS Warmup' feature that keeps the detector quiet for a 'user set' number of seconds or until a GPS connection is established with your detector and/or iPhone. Useful for parking garages etc.
• Added ability to tun ON/OFF the function of SpotLocks automatically writing the location to your detector's "manual mute" memory when a locked SpotLock is created (This setting is found on the map screen).
• Added the ability view and change the R4 mode between Advanced, Highway, City and Auto to the main alert screen.
