UNIDEN come on! ### 2/5 — It works…keep wishing for improvements *2023-05-07* Does it work?….yes it can 🤔 Is it finicky?….you betcha! 🫤 Is it unpolished?…yep! 🫤 Does it look like a high school class project?….definitely! 🫤 I’m not going to crab about the 3 second delay. It doesn’t matter if I’m in another part of the house. With all this said…as I write this…I AM listening to my BCD536 on my iPhone14+ in another part of my house via local LAN. Far away from the 536. Nice👍 If I switch to another app…Siren continues working in the background. Nice! 👍 I have waited years for this functionality! And it’s finally here! Frankly, I gave up on any hope of a remote control app. Perhaps it’s simply class action lawsuit avoidance. Don’t sue us…We fulfilled our promise(barely) My hope is that Uniden will continue to improve this app or at least let another development team clean it up. 7 YEARS WITHOUT ANY UPDATE ?!? I WOULD PAY (can you hear me Uniden? I WOULD PAY) to use a much more polished and stable app. Like many others have pointed out…this app looks and functions like a beta convention demo app. But it can work!! I enjoy using my Uniden scanners. I own 4 different models. They work well. Please don’t let Siren die 😵 on the vine. ### 2/5 — Please update!!! *2022-02-20, version 1.1.2* This needs to be updated. ### 3/5 — Bluetooth please!!! *2021-11-29, version 1.1.2* That’s all I ask for- audio out capability to bluetooth headphones. Otherwise the app is good enough. ### 3/5 — Works. But.... *2020-12-05, version 1.1.2* Does not output sound via Bluetooth or the headphone jack :( Tried on multiple iphone models. You’re forced to listen via the speaker on the phone, not ideal. ### 2/5 — Very basic and outdated *2020-04-11, version 1.1.2* Has not been updated for several years. Functional but only in very basic form, and could do much more. ### 2/5 — Just a selling point *2020-04-03, version 1.1.2* It has become obvious that Uniden created this app just so that they could claim they had an app that could control their scanners. And it does - to some degree. But functionality is very limited and is generally more trouble it is worth. The fact they have made little or no attempt to improve the app for years speaks volumes. Overall very disappointing, as it could be so much better. The iPhone has more than enough ability to provide and edit the entire database, but there is not even a token effort to do this. ### 1/5 — App doesn't work *2019-12-07, version 1.1.2* This app doesn't work and hasn't been updated in years. The scanner is still being sold and marketed with this functionality. I'll be returning the scanner if I can't get it working remotely as advertised. ### 1/5 — Garbage, complete and utter garbage *2019-10-09, version 1.1.2* App obviously not supported. Every function causes app crash. What a shame, come on Uniden! ### 1/5 — Disappointed and sad *2019-05-14, version 1.1.2* One of sadness applications in the app store. No support and app completely useless in IOS 12 and Android 9. I'm unable to up address of the scanner because accept button off the screen. Spend your hard earn money on trx2, DMR audio is much better. ### 1/5 — It could have been great *2019-04-02, version 1.1.2* After waiting over 3 years for Uniden to fix this app I have come to terms they aren’t going to fix it. This app had so much potential. Really a major ball drop from Uniden..... ### 3/5 — Room for improvement *2019-03-31* Useful around the house as radio itself is in office. A little buggy but not bad. I would gladly pay for it if it had more controls for the radio remotely. ### 1/5 — Worthless *2018-08-24* This app is is not useful at all. When will Uniden update it, so we can effectively control our BCD536HP scanners as well as listen to the audio. Applications like ProScan on Windoze works like a charm. Maybe uniden should work with that developer to make something useful. One drops $500+ for a scanner and expects good software for the device. Come on Uniden, get to work! ### 1/5 — Still no update *2018-03-11* Basic app with some basic functions. Really needs updating with the ability to adjust the volume. I have the scanner in the back of my truck hooked to a speaker up front. Was hoping this was going to be more of a remote with more functions. Not been updated in 2yrs ### 1/5 — Garbage *2018-02-17, version 1.1.2* This app WILL NOT work with iphone x. crashes and wont connect to scanner. Uniden should fix it properly or pull it from the app store. ## Most critical reviews (10 lowest-rated) ### 1/5 — Outdated *2026-03-21, version 1.1.2* Spend thousands of pounds with this company and they can’t get this up updated ### 1/5 — Awful. *2024-12-21* I try to use this on my SDS200. Rarely works even with a dedicated wired LAN connection. Frustrating to operate and often just stops responding. Tapping the mute button on the app is an automatic crasher. Hasn’t been updated in 9 years. This app is an orphaned afterthought. Too bad. It could have been very useful. I’d have paid for a robust mobile solution. ### 1/5 — Trash ... *2023-12-02, version 1.1.2* Don't wast your time. Drops connections and packets. ### 1/5 — Not very practical *2022-03-27* Considering then large wad of money I spent on the BCD536HP, I am not impressed how unstable this app is. I would have expected Uniden to have fixed this app by now. ### 1/5 — No Audio on SDS200 scanner *2021-08-23, version 1.1.2* The siren app worked fine with my BCD536HP connected to WiFi. My new SDS200 is connected to the Ethernet port and I get no audio from the siren app. ### 1/5 — Needs work. *2021-07-06, version 1.1.2* The possibilities are endless! But …still not right. ### 1/5 — False advertising *2020-12-08, version 1.1.2* Anyone who has purchased the bcd536 scanner and were lied to about this function, I ask you to go to consumeraffairs.com to sign up and write a review of how there is no U.I. For the wifi function. It's time for retribution! This scanner cost too much for them to get away with this! Got a reply from consumer affairs. They need more reviews to publish a uniden page. Sign up! Speak up! ### 1/5 — Bad app *2020-12-02* At the highest price of the scanner I hope a better app and update for all scanner products. ### 1/5 — Needs help *2020-11-22, version 1.1.2* Still use the app but it keeps crashing now. Needs an update. ### 1/5 — Terrible *2020-05-22, version 1.1.2* This app almost never works.. such a shame they abandoned it ## Most praised reviews (10 highest-rated) ### 5/5 — Run with No issues *2025-06-28* I have Zero issues with this program run off a SRS200 ### 5/5 — This app works great *2022-02-23* Remember to use the app and get the most out of it. 1 put your WiFi in the BCD536HP 2 look inside the radio WiFi information To see that the ip is there. 3 on you siren app. Information; settings; before you hit agree, check you have to put the same IP address in the siren as the radio has. 4 if you ever have a issue hit on the app. Information; setting agree. It will come right back. 5 if the app. Is not responding pull the USB out of the BCD536HP and plug it back in. I’ve used this app. For two and a half years. Most of the problems people have with this is they don’t know what they are doing. ### 5/5 — Works perfectly!! *2020-06-26* Had no problem setting up or operating app! ### 5/5 — Works fine *2018-03-20* This ap works fine for me over wifi. I haven’t tried it mobile. I wish it provided total control over the scanner, but it does not. ### 5/5 — Works Great *2016-05-05, version 1.1.2* I almost didn't buy the BCD536HP because of all the bad reviews on this app. I was leaning toward the Home Patrol 2 because of the interface. Luckily, I found a local guy selling one and asked if I could bring my Ipad to make sure it works. I was able to connect just fine after have both on same wifi connection. Sound quality is good and works on iphone too just fine. There is a learning curve to setup and youtube provides a few good videos to help you set it up. The only issue with audio I found is what others have found is that if you have something plugged into the headphones jack when you start app it still goes to iphone or ipad speakers. You simply unplug and plug it back in and its works fine. All I can suggest to ppl having issues is make sure you have up to date iOS and find the right ip on the same network on your scanner by going to the wifi settings in the menu and hitting the show wi-fi Information. Even though this scanner has ez to program HomePatrol zip code features you still need to be good at tuning in exactly what you want to monitor. Good luck out there and happy scanning the bands!!!! ### 5/5 — Updated review *2015-03-24, version 1.0.9* After doing my research and updating the scanner & wifi dongle firmware, it's now working like a charm. ### 5/5 — Works as advertised *2015-03-21, version 1.0.9* Not sure of why some say this doesn’t work, or work well. Must be operator error. And the hurt feelings because it doesn’t magically let you listen to your scanner from home yet is just silly. NOT “buggy" at all. SOLID and works great! ### 5/5 — It works! *2015-03-16, version 1.0.9* Looking forward to future updates of this app! ### 5/5 — Siren app works great so far!!! *2015-03-16, version 1.0.9* Works well connected right up!! :) ### 4/5 — Works fairly decent with SDS200 *2023-07-24* This is probably an orphan app but it is still usable, at least within a local area network… --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
