Reduces a lot of false alerts ### 3/5 — Speed limit issue *2026-08-09, version 1.24.2* Not sure why speed limit is enabled even after I disable it, it keeps coming back on.Never had this issue until the update. ### 5/5 — Much improved *2026-07-08, version 1.21.10* 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. ### 5/5 — Excellent App. Saves me lots of money 😜 *2026-07-02, version 1.20.2* 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. ### 1/5 — Use to like it *2026-06-06, version 1.20.2* 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. ### 5/5 — The R4 is so annoying without this app *2026-03-28, version 1.17.2* Truly works like magic it removes the false alarms and visually looks great ### 5/5 — Must have *2026-02-15, version 1.17.2* If you own an R4, just get this app. ### 5/5 — Excellent *2026-01-25, version 1.17.2* 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 ### 4/5 — R4 Companion is the perfect companion to quiet your Uniden R4 *2025-12-22, version 1.17.2* 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. ## Frequently asked questions about R4 Companion ### What is R4 Companion and what does it do?

Thanks! • MyRadarIQ™ - Threat assessment intelligent system for the radar companion series of apps. A new meter, visible at the top of the main alert screen, will show a graphical representation of the probability of a police presence (Ka or Laser) in the direction of your travel. Using your personal alert data, whenever a high probability exists for an encounter ahead, you will know about it well in advance of facing the actual threat. The meter will go from yellow (low threat), to orange (medium threat), to red (high threat) and flash on and off and a voice announcement will occur. The meter will also flash red when a Ka or Laser alert is actively being received to help draw attention to the alert. Probabilities are calculated down to the actual day of the week you are traveling, increasing the accuracy on any given day. • Instantly see your changes when modifying detector settings. • Flashes screen when an alert occurs. • Pair it and forget about it! It just works. *New* - Robust Bluetooth connection engine works seamlessly in the background to manage all your R4 devices. ***TIP: Setting the main volume for the detector to 0 on the main alert screen and enabling the detector alert tones, will eliminate the brief audio "blips" you would normally hear when a mute command is first sent to the detector. Only potential threats will then trigger audio through your speaker or audio system providing an extremely quiet ride. ### 1.23.3 — 2026-07-22 Now works with CarPlay!
