    R4 Companion Reviews


    • Why no Apple CarPlay?

      This seems to be a pretty good app except it be better if you could put it on the Google CarPlay in your car. this way if you get a phone call, you can still see the alerts on your car display.

    • Only on thing

      Love the app. Only thing keeping me from giving it 5 stars is no ability to change the screen colors. Other than that love it.

    • Interface is limiting

      The speedometer and compass features on this app are very distracting. The creator of this app should take a page from Uniden and allow the option to minimize visual distraction when radar/laser updates are not happening. Uniden detectors come with a 'scanning screensaver' that can be turned off, atleast.

    • Bluetooth connectivity

      The only reason this isn’t 5 star is Bluetooth constantly disconnects and reconnects, over and over. Update: thank you for your quick response Angela. All suggestions are in place as suggested. Distance from R4 to Android is less than a foot. Good Bluetooth signal strength. It also happens with both vehicles. Any other suggestions? Thank you

    • Indispensable

      It is difficult to imagine that this app works so well with just its default settings that it made me believe my R4 wasn’t working properly. The truth is, I was getting a vast number of false alerts that this app helped to mute - while Keeping track in the log for later review. The only thing I haven’t figured out how to do it to use the map function in the app to go back and mark certain spots as false alerts. You can mark the type of alert, but there doesn’t seem to be away to mark as a false alert. Otherwise perfect. The in app settings config for the R4 is very helpful too.
