Great app

After the last update you can’t tap the phone screen or CarPlay screen to mute the detector.

Must Have!

Great app to run with along side Waze for any police stationary laser. Reduces a lot of false alerts

Speed limit issue

Not sure why speed limit is enabled even after I disable it, it keeps coming back on.Never had this issue until the update.

Much improved

Blue tooth connection is more reliable now if you keep the app open and ignore the apple warning it is using your location which isn’t correct if Bluetooth isn’t connected on R4 display.
If the Bluetooth is your only connect to your helmet on a bike I would recommend a secondary warning system like the LEDs that plug into your audio out.
It is great to have audio choices for information on a bike so you don’t look at a phone.
Having logged GPS speed and radar frequency is helpful if you do get an infringement as the police are not honest about the calibration and accuracy of their equipment. They ignore and hide the manufacturers specifications for their measuring equipment.

Excellent App. Saves me lots of money 😜

Excellent app. I love the configurations to disable the frequency voice announcements that are totally irrelevant unless you’re a power user. I use it on a motorcycle and it works like a charm.

What I would love to see is carplay support.

Use to like it

R4 keeps disconnecting via Bluetooth. 40 mins or 1 min is the connection time. Other apps do not disconnect.
Tried factory reset on radar, iphone, delete app and installing old firmware on r4. Still the same issues, resorting to using other apps until fix. If not well….

June 6: the connection between the phone and the radar was excellent, with the distance between them being less than two feet. However, it appears that wireless car play is interfering with the proper functioning of this app due to the same Bluetooth frequency or within the same parameters. Wired CarPlay is the only method that works without connectivity issues with current 1.39 firmware. For some reason 1.36 and 1.37 works without connectivity issues while using wireless CarPlay.

The R4 is so annoying without this app

Truly works like magic it removes the false alarms and visually looks great

Must have

If you own an R4, just get this app.

Excellent

Wonderful 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

R4 Companion is the perfect companion to quiet your Uniden R4

I 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.

Inconsistent Bluetooth

If you are relying on the Bluetooth connection between the R4 and the App to get warnings, it may not reconnect after stopping and power to the detector cycling. You will be riding blind with the app unaware the detector is screaming slow down!

Uniden Radar Detector R4

Love this app works like a charm, and it looks futuristic.

R4

Works 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

Edit : Great app for the R4

Edit: 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.

Response from developer

Hi Ruckinjoe, Sorry you couldn’t find the setting. Tap on the ‘audio settings’ button on the bottom of the main alert screen. On the audio settings page, you can set the ‘limit speed’ warning. Turn it on/off or set the speed for the warning. Please reconsider your review now that you know where the setting is. Thank you. -Mark

You need this.

Makes having a radar detector more effective and less annoying! I highly recommend it to every R4/R4w owner.

Almost

I would give 5 stars but the app asked for a review as I passed a cop….

Great for motorbike

Works great and gives an easy interface to the detector. Easy way to route the alerts to the helmet via Cardo etc. if you don’t need laser detection the detector can go anywhere.

Great for settings.

Be amazing if this app was added as an option for CarPlay.

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.
