R4 Companion App Reviews

Very impressed with the R4 companion app. Initial release was very polished and I encountered no issues! My rides have become much quieter with K band falses. I was also able to increase the sensitivity on my detector confidently knowing the companion app would help filter out those dang Hondas haha. Excited to see if any new features come out!

This is my first radar detector app and it has been an easy learn. Does what it’s supposed to well. Recommend!

This app is a solid companion and a must.

After using the radar alone and trying the this app with it I was amazed how it helps turn downs false signal on normal roads. I do have one feature or bug I still can’t figured out. The city over speed warning comes on even when I turn it pass 60. I want to go faster than 60 and it does it on the toll road too. I have to reset to factory settings to get rid of it. I hope they can tell me how I can turn it off or and fix the bug even when I’m on the highway with speed faster than 60. Update: lo

Excellent app very well thought out! Use it everyday no glitches, thank you!

This App takes the R4 to a new level. Love the customization options. As someone who operated a radar unit for 30yrs and knows what radar units are being used I was able to narrow down the alarms to just police radar. A suggestion for a future update, I would love the ability to auto MUTE the startup process. I don't need the radar detector making all those annoying announcements and beeps every time I start my vehicle.

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

This app is a great utilization of the R4’s Bluetooth compatibility. Adds some really useful features to my R4. Does especially well at filtering out false alerts. Great app, easily worth 10 dollars.

Love this app so awesome how it works as a display for my radar can’t wait to see what’s coming next love my radar too.

I typically don’t write reviews for apps, but since this is a paid app and an app that performs flawlessly, the developer deserves to have a positive review written. I would’ve paid $20 for this app. It allows you to adjust most settings that you would normally have to do on the R4 itself. Also, you can see many more details of what the R4 is detecting that the small display can’t show. If I had one recommendation it would be to have a Landscape option that also flips the display so you could

Great app for $10! Makes your R4 a new device if you don’t already know how to use the basic functions

The app works great, connects to my r4 fast and has a easy interface. Only problem for me is the advanced false assist, I live in a small town and the cops here still use k band. More times than not the app will “ghost” the cop car and act like it’s a Honda/acura. My solution would be able to tweak the advanced false assist, make it so your able to turn off ghost mode, while keeping the other options so you don’t have to completely turn false assist off.
