R4 Companion App Comments & Reviews
R4 Companion Positive Reviews
Edit : Great app for the R4Edit: After being advised of the one setting that made me dislike the app was in a different tab. Now the settings I was looking for are now changed I really like this app! Thank you for pointing it out from the Developer and have now given the app a 5 star. I like the look of the app and its functions. I have a big issue with the app changing settings on me automatically. Example is the speed limit warning. Just having the app open and not even going into settings on the app will change it for you every time. Very annoying when on the freeway and get a warning of going over 70mph. I cannot find this setting in the app which means I have to change it on the device every time I open the app. Not easy when driving and the R4 is in a spot not easy to get to. Also not all the settings are available on the app. You get the most of the basic settings. These are reasons why I give it a 2 star..Version: 1.14.1
Good appAfter 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: love this app as they provided instructions how to turn off the speed warning limit. 5star app!.Version: 1.06.8
IndispensableIt 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..Version: 1.07.3
Must have app for R4 ownersI 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 use it as a Head Up Display against the windshield. That would be awesome..Version: 1.02.11
Great app, definitely worth the $10, 1 small problemThe 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..Version: 1.05.16
Very Good App - well worth the $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..Version: 1.06.8
ExcellentWonderful app, works extremely well, worth every penny. Optimized and runs better than 95% of apps I’ve used and is actually very functional. I love the report at the end of the drive; as someone who is enthusiastic about tech, it’s cool to see what it’s actually doing for me! Bravo.Version: 1.17.2
Bluetooth connectivityThe 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 iPhone is less than a foot. Good Bluetooth signal strength. It also happens with both vehicles. Any other suggestions? Thank you.Version: 1.07.3
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!.Version: 1.01.11
Modern radar detectors are complex.This app demystifies what is going on in the radar detector and eases customization. I would like a more detailed manual, but I think that since I’ve only used it for about 6 days, the info will come organically. Nice app..Version: 1.08.9
Interface is limitingThe 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..Version: 1.07.3
Good, Not Yet CompleteAn improvement in controlling the R4 and worth its modest price. However, the IOS version has no options to change the R4’s primary display settings for speed, compass, scanning, time, etc. I was disappointed these major user interface choices are missing and would rate the app 5 stars if it had them..Version: 1.09.4
Amazing.I’ve downloaded countless apps, however, this is the only app I’ve ever bothered to write a review for. This app exceeded my expectations and more. If you think $9.99 is too much, consider you spent $300 on the r4. This enhances the R4 greatly. Much appreciation to the developers..Version: 1.09.4
R4Works well with the R4..only issue is if you are not US based you need to change your phone account region in IOS to be able to install the app.Version: 1.14.1
Very Useful for R4This 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..Version: 1.02.11
SimplicityGreat app for $10! Makes your R4 a new device if you don’t already know how to use the basic functions.Version: 1.03.13
You need this.Makes having a radar detector more effective and less annoying! I highly recommend it to every R4/R4w owner..Version: 1.14.1
Love the appLove 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..Version: 1.02.11
Only on thingLove the app. Only thing keeping me from giving it 5 stars is no ability to change the screen colors. Other than that love it..Version: 1.07.3
Why no Apple CarPlay?This seems to be a pretty good app except it be better if you could put it on the Apple CarPlay in your car. this way if you get a phone call, you can still see the alerts on your car display..Version: 1.07.3
Great AppThis is my first radar detector app and it has been an easy learn. Does what it’s supposed to well. Recommend!.Version: 1.02.11
R4 companionExcellent app very well thought out! Use it everyday no glitches, thank you!.Version: 1.06.8
The R4 is so annoying without this appTruly works like magic it removes the false alarms and visually looks great.Version: 1.17.2
Great for settings.Be amazing if this app was added as an option for CarPlay..Version: 1.09.4
Must haveIf you own an R4, just get this app..Version: 1.17.2
Must have appThis app is a solid companion and a must..Version: 1.03.13
Uniden Radar Detector R4Love this app works like a charm, and it looks futuristic..Version: 1.15.10
R4 Companion is the perfect companion to quiet your Uniden R4I just wanted to thank the developer(s) of this app. I can tell that She has a lot of inside experience and expertise with radio signals and this app is a reflection of that. A driver that knows what they got. High performance vehicles and where and how the bogies get detected. This app was coded for admins who understand what it takes to connect fast and customize what you want. This $9.99 app is a total game changer. I now have a quiet device with data logging to a map. My only feedback or maybe Christmas wishlist. Built in media player that lets the user choose the preferred player and allows controls on screen. When using said media player. Lock all volume to its mode or stream. I have a stereo that auto switches from Spotify to Carplay dock mode when Any alerts come on. I tried HFP but it’s too slow between my phone and Kenwood head unit even with adjusting delays. Please add mini player mode that can allow alerts without total music stoppages. Apple Music, Spotify, Youtube Music. My second wish is for Waze integration. Tell me where the bogies are planned based on the API and tell me to slow it up. In conclusion my Kenwood likes to dance between two modes when selecting this app to view bogies and speed. I know she will understand like she always does and will fix this. Anyways this is the best app for the R4 ever! 🥰 Much Love and Merry Christmas and Happy Holidays..Version: 1.17.2
