The amp modelleling is great. The application is a disaster. Had it running on an Android phone then it stopped connecting. Tried every permutation of turning it on and off with every imagionable connection option. Nada. Uninstalled/reinstalled many times. Once the software appeared then quickly disappeared and im stuck with an error message that I need to connect. Please, hire some competent programmers.

I was really hoping this would work. I have used OTG with several other devices, this won't even connect. The app also seems half cooked. The opening screen alone that is supposed to read "Connect Device" is misspelled. It reads "Connet Device." This shows not a lot of care was put into development of this app. I love my amp academy pedal but I was hoping I could edit presets from my phone instead of having to use a PC. So this is really disappointing. I will probably sell the Amp Academy soon.

The App or the Pedal??? It is super handy to not have to get my laptop out to tweak the settings, but there appears to be issues with "dragging the effects" to change the order... however this could be a problem with my Amp Academy. Either way, it feels like there are a few little glitches that could be sorted, but not enough that I can't work around.... Cos the pedal is a Godsend - for the money 👍🏾.

The app worked fine for me even though I've seen a lot of negative reviews. Whatever problems it had seem to be resolved. Works great. You need to use the editor software to change amps and cabs, but everything else can be changed on the app. Very handy for making quick adjustments.

It doesn't work in my android phone. I'll change my review of this if you help me troubleshoot this problem. It can't read or connect my phone to my nux amp academy pedal.

It works fine but unfortunately it lacks the ability to change impulse responses including the IR low cut and IR level.

I have been very impressed with Nu-x as a whole, but this app needs improvements. Connection issues and no clear solution online? Nope, I've better things to do.

Does work on my old phone Oneplus Nord, recently upgraded to Xiaomi 13 and it doesn't work. I tried everything. Functionality is fine for little adjustment here and there. Full functionality only through PC. Software works good on my MacBook Pro M1.
