Very Disappointed
Once you overcome the nightmare of trying to pair devices, it looks fairly good. Major areas of disappointment are it downloads the digital repeater list only to your phone where the app accesses it. You don’t seem to be able to upload it to the radio which is crazy. It only deals with digital and not analog at all. Again crazy omission. Potentially it could be great, but let down by major omissions.

Nice basic app
This app has worked well in the past with my ID-52 but lately it has started crashing when I use the map function to see a station location. Annoying
Worst iPhone app I’ve ever used
This app is shockingly bad given it’s produced by a globally respected company like Icom. It is non-intuitive, looks terrible and crashes constantly. The only upside is that the Android version is even worse. Refresh this, please, or better still, open source it so that the community can start to make this usable.

Connection failure
I’ve spent 3 hours with iOS and the Android equivalent app trying to connect (pairing works) the ID-52E Plus and still haven’t succeeded. This is definitely not “seamless” in my case. Yes I have changed CI-V addresses and various other options, reset and reinitialised. I would give it zero stars if I could.

Crashing
Crashing ou on iPhone os26.4.2 when trying to use map to find repeaters
App crashes on map screen
This app works for everything except when on the map screen. The entire application will crash when looking at the map section. Icom needs to fix this.
Almost perfect. App closes when opening the map and moving about. Annoying!
App closes when opening map! Annoying.
Fails with ID-52A Plus on iPhone 16 and iPad Pro
Update, 2025-06-05. Got further along but still not staying connected to the app. I was mistakingly trying to pair using the iPhone’s Settings: Bluetooth: Pair. However; just using the ID-52A Plus’s Bluetooth pairing function and then pair in the RS-MS1Ii app. It says paired but then a notification on the iPhone says not connected. Tried numerous iterations of settings from YouTubers but no luck. This app, as advertised by Icom for the ID-52A Plus, does not work for my iPhone 16 Pro and iPad Pro. This is the major reason I upgraded from ID-51A. Bluetooth is a very mature and well understood technology and so there is no excuse for Icom to not fix this ongoing problem.

Fails with ID-52A Plus on iPhone 16 and iPad Pro
Error message on iPhone and iPad: “Connection Unsuccesful “ICOM BT(ID-52)” is not supported” Forget Device?” Bluetooth, as advertised by Icom for the ID-52A Plus does not work for my iPhone 16 Pro and iPad Pro. This is the major reason I upgraded from ID-51A. Bluetooth is a very mature and well understood technology and so there is no excuse for this failure to fix their error(s).

Not for ID-50
It would not have been difficult to make this app function with a USB connection to an iPhone, but it is Bluetooth only, so it’s not compatible with the ID-50
iOS 18 does not work
ID-52 and does not stay connected to iPhone 15 Pro on iOS 18
Once again quick fix from the Icom Devs
I reported a connection bug a few weeks ago and the excellent devs from Icom knocked this out quickly. Thank you! Once again, I am an Icom user for life. Their support is second to none!
Useless
I bought the icon ID 52 plus completely unusable to program and now I’m out like 800 bucks wish I would’ve went with another brand. The only thing I can get the radio to do is whether an FM radio.
Don’t bother- doesn’t work
Clearly they no longer support this app. Bluetooth implementation no longer works. Android app works. Try that.
Rubbish
Does not work either on the IC-705 or ID-52. Brilliant radios but this software that is supposed to support them is absolute rubbish.
Works fine
The app works great for me. Connected to my 705 even from another room.
IS-52 and iPhone 13 won't connect
The app is worthless. Cannot connect to iPhone 13 Pro Max. Tried two phones. Pairs and connects, then drops the connection. Too bad. Gave up.
ID-52
Connects and immediately disconnects from iPhone 14 with most current iOS. such a frustrating waste of time. The app looks useful, but cannot get it to connect to the radio for more than two seconds.
Needs better pairing instructions
Took me a long time to figure out how to pair the app to my ID-52. It’s very counter-intuitive. The trick is to use the menu setting “pairing reception” on the ID-52 NOT the “pairing / connect” option as you would expect. Once I got the app connected it’s pretty amazing to be able to have stations appear on the map in real-time. I hope Icom will continue to work on the app as it would be interesting to see what else might appear in future.
