### 1/5 — Horrible

*2026-05-26, version 3.0.5*

Could this be any worse?  It constantly drops connection with my ox stomp. I have to restart it constantly just to change one microphone. Sometimes it will change cabinets, but not microphones. Sometimes it will change microphones, but not cabinets. Sometimes it won’t let me rename something. Sometimes it crashes getting it to work is basically impossible. I have updated both the firmware and the app to the latest versions as of late May 2026 what a joke fix this or just go away.

### 1/5 — Buggy, unreliable, and poorly designed

*2026-04-02, version 3.0.4*

Multiple attempts are required to connect to a pedal (either wired or bluetooth). Then when the pedal does connect, don’t you dare let it go idle, or exit the app. You’ll have to start all over again. At times only certain adjustments will reflect on the pedal. And the Bluetooth connectivity is really buggy, causing presets to not be saved, and the app crisscrossing parameters into the wrong preset and messing up the ones you did have saved. I have the Ruby, Lion, and Ox, which all sound great. But the app is nearly useless and makes me consider selling the pedals.

### 1/5 — You thought Source Audio was bad?

*2026-03-31, version 3.0.4*

Ok. Let me start here. The pedal sounds incredible. Every bit what I had hoped for in a versatile delay. Great. Good job. 

The bad:

The midi interface is frankly, the worst I have ever worked with. I have been SCREAMING INTO THE VOID trying to get this app to acknowledge that I am pressing ‘CONFIRM’ trying to assign a PC preset. It WILL NOT WORK. Why? Tell me why? It worked once. Hadn’t worked since. I bought this in the hopes that it would be a high quality addition to my gigging board and work comfortably alongside my boss and eventide pedals WHICH HAVE ON BOARD MIDI FUNCTIONALITY THAT WORKS SIMPLY AND EFFICIENTLY. 

I have bought a secondary hub for $50. I bought a new USB C cable for $14. I had to upgrade my power supply to support the 400 mA requirement. $279. I have to use a slot to power the midi interface. I had to download a SECOND app to exit the midi interface. I have had to interact with computers 8 times. 

I still haven’t successfully midi switched this G*D damned pedal. W. T. A. F. 

I SHOULD BE PLAYING GUITAR RIGHT NOW.

### 1/5 — Horrible

*2026-03-31, version 3.0.4*

Bought 2 UA pedals. This app is so bad I returned both of them.

### 2/5 — Pretty bad

*2026-03-29, version 3.0.4*

Whenever the phone locks itself you lose the connection to the pedal and you have to wait strangely long to reconnect (latest firmware on the pedal ofc). Another really strange design choice is that there is no way to see what the settings were for a preset, because the primary pedal controls are not represented within the app UI. (There isn’t even a way to sync up your physical knob positions with a preset so you can continue adjusting it. It would be easy to light up LEDs on the pedal to indicate whether a knob is greater or lesser than the preset value). The app doesn’t work well on the iPad either… controls don’t follow your finger.

### 1/5 — the app is terrible

*2026-03-24, version 3.0.4*

control and the pedals themselves are not great

### 1/5 — It doesn’t work

*2026-03-16, version 3.0.4*

I have a UAFX Dream and honestly I want to return it because I can’t get it to work…

### 2/5 — Good but problems remain

*2026-02-05, version 3.0.4*

It used to be faster to connect, but with latest firmware updates I now have to wait for the app to fetch preferences from the pedal. This is new, slows me down and is just a bit irritating. 
Also only having one saved preset accessible from the pedal is a bit poor too.
Good job it sounds amazing, but the clunky interface lets the whole experience down.

### 1/5 — Pretty useless - really disappointing from UA

*2026-01-30, version 3.0.4*

This app is terrible, and it ruins some good-sounding pedals. UA support is condescending and dismissive. They will tell you recent updates fix the many issues, but nothing has changed. Still totally unstable and virtually unusable.

### 1/5 — ox stomp...

*2026-01-16, version 3.0.4*

attack slider for 1176 works maybe 1 in 50 times after lots of reconnecting to bluetooth, restarting, forgetting, pairing ect.  Sooooooo bad overall.
