### 2/5 — Issues Connecting

*2026-08-14, version 1.1.0*

Barely wants to connect. Needs updating.

### 4/5 — iPad Landscape Mode needed

*2026-08-02*

The app works as advertised.  I’ve have no issues connecting to my iPhone or iPad.  Adding landscape mode for the iPad would make it more user friendly to keep app open while using the amp.

### 1/5 — Does not connect

*2026-07-06, version 1.1.0*

I have a gen 3 100w and when it scans for devices all it shows is a black screen it does not connect at all

### 5/5 — Needs work

*2026-06-27*

When I download a preset from tone exchange it takes 30 to 60 seconds for it to actually load on the amp. Also, the LEDs on the app go out of sync with the LEDs on the amp.

### 2/5 — eh

*2026-06-21, version 1.1.0*

great amp not as great app. definitely needs work, gotta sign back in every time i open the app. very rare it works like its supposed to.

### 1/5 — Terrible app that lets down Boss

*2026-06-08*

Update.  Impossible to use with Artist Series mk 3.  When I use in combination with a foot switch, app seems to discard effect settings that were previously selected on the patch and also things like amp volume etc. Found it is totally un-usable to make quick tweaks on the fly which makes it pointless.  Think there is a problem between interaction of foot switch, amp and app.   Boss - very disappointing and your developers need to fix this. Also, regularly loses connection with MIDI adapter and then can’t get it back.  Terrible user experience in UI. Way too clunky and no thought to how users might use it. Boss needs to put some investment into this as it is the way the industry is moving.  At the moment.. this app is terrible.

### 3/5 — Good but...

*2026-06-08*

The app itself is great it just needs landscape veiw and overall needs to have the bluetooth integrated into the amp also it just needs to be simplified

### 1/5 — I don’t get it

*2026-05-27, version 1.1.0*

Why does Boss make a great amp but garbage apps to go with them?  Really strange that they should get it so wrong.

### 1/5 — Forgets library

*2026-04-14*

Best part is how when it signs you out from the Roland account (forcibly) then forgets everything you had in your library… or if you shut off the amp while the app is still searching for the Bluetooth connection it also yeets all memory.

### 3/5 — I mean it works…

*2026-03-25*

If you can get past the outdated/slightly confusing user interface then this app is great! Additional FX and extra parameters in the app make dialing tones that much more fun. With all the extra control you get in the app, the Bluetooth module is very worth it. Just wish they would overhaul the UI. I want landscape mode on my iPad!
