★★★★★Wow!
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!
★★★★★Great App
This is my first radar detector app and it has been an easy learn. Does what it’s supposed to well. Recommend!
★★★★★Must have app
This app is a solid companion and a must.
★★★★★Good app
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
★★★★★R4 companion
