## UAFX Control Reviews in United States

### *---- "Useless"
Every time I try to connect to one of the pedals, the app crashes.
-- drlaine, 2025-01-01

### ***** "Worked Great"
I was super happy with the usability. I found the pedal and synced it easily. The presets were super tasteful. Very pleased with the entire experience.
-- skizzyler, 2024-12-14

### *---- "Why Why Why?"
I normally do not write reviews, but this amp in combination makes me speechless. How can a such capable company like UA make such a poor decision. This app and the connection to the pedal is so unreliable and slow. It would be a better world if that app would not exist. UA must really hate their customers.
-- xermantas, 2024-11-16

### *---- "Connects to Bluetooth one out of 50 tries"
I’ve tried everything UA suggested, re-downloading app, resetting app, resetting pedal, forgetting pedal, re-adding pedal, re-pairing pedal. Nothing works. I’ve owned the pedal for three years now, and the app has only connected perhaps once or twice.
-- tr1999, 2024-11-13

### **--- "More input"
What this app needs is the ability to edit settings in the app (like the Ox Stomp implementation). Needs the ability to connect to all pedals that are powered up and Bluetooth connected - - add tab pages for each pedal and allow the user to quickly go between pedals. Give the user more options to load more then 1 preset into the pedal, or open up the interface to connect to a midi floor pedal that could then bring midi into the UAFX and then UAFX connect to the pedal.
-- Buickwilson, 2024-11-13

### ***** "Nicely Done"
I just bought the Enigmatic and downloaded the app. The Bluetooth sunk up easily and all the controls worked well from my phone to the device. 

I had the pedal sounding fairly decent on its own but the extra features on the app were essential for getting it fine tuned.

Nicely done!
-- Jimmie Ingram, 2024-10-26

### *---- "Great HW crap SW"
Impossible to add the Lion pedal. Enigmatic was no problem.
-- Mjtyahd, 2024-10-24

### *---- "Enigmatic indeed"
I have always shied away from pedals that need app support, maybe I’m old school. I can see why this app has such bad ratings. Just received the brand new Enigmatic and the app is just frozen. I was initially able to connect the pedal to my phone via Bluetooth and the pedal loaded the presets as I expected however, since then I cannot access the pedal through the app, despite disconnecting from power multiple times, reestablishing, the Bluetooth connection, and closing and reopening the app, if this doesn’t improve immediately, this thing is going right back to Sweetwater.
-- T00min8r, 2024-09-28

### *---- "App stopped working"
After updating my Dream pedal as prompted by the app, the app will no longer connect to the Dream pedal.
I reinstalled the app, and no luck.
Amazingly lackluster performance from a first in class pro audio company.
-- zweebop, 2024-09-12

### **--- "Great products, weak app"
Everyone knows these issues with the Bluetooth connectivity exist but for whatever reason it seems to never be fixed.  Great products but make the app better - you must have great software developers for all of the plugins you have for sale.
-- TheGuy00781, 2024-08-28

### **--- "Galaxy"
I just updated my galaxy to the latest firmware and now the pedal has become a $300 paperweight. I’ve tried unpairing the Bluetooth from my phone, plugging into the computer and resetting via the online instructions. For pedals that are in this price range I’d never expect the tech issues. The 3 lights on the head select just flash red and I’m not getting any lights from the effects buttons. I have opened a ticket with UA but I would strongly advise against these pedals based on the connectivity issues. On the up side when the pedal works it sounds great. I was really looking forward to the reverb always on update.
-- MossWartortle, 2024-08-26

### *---- "Connectivity issues"
Most of the time pedal will not connect even restarting both the pedals and the phone.
-- andresriveros, 2024-08-13

### *---- "Didn’t work so far"
I got the Lion. Tried to connect on the app, it prompted me to update the pedal on my computer. After that, every time I select the pedal on the app, it crashes. Tried to reinstall, re-add the pedal, nothing.
-- Guitar Gear Geek, 2024-07-16

### *---- "Frustrating"
The app itself is an absolute pain to use with the OX STOMP. Precise adjustments are impossible to achieve with the sliders. Even more frustrating is how difficult it is to demo different sounds. — Want to spend 30 seconds trying out a cab? Oops, the phone went to sleep and now the app has disconnected from the pedal. Please start over — The OX BOX has a desktop app. It is ridiculous that the OX STOMP does not.
-- ppl_prsn, 2024-06-19

### ***-- "After updating pedal firmware, I can’t connect to the app"
Was working fine. Now o can’t connect at the latest firmware, did everything the faq said to do and still
-- Devbo butt punch, 2024-06-07

### **--- "Accessibility is a big problem in this app"
I've had no success contacting UA about the accessibility issues with this app. Not sure where else to turn. This app is very hard to use with the built-in iOS screen reader VoiceOver. 
I give UA some points for being able to change the presets with VoiceOver, but trying to use the edit page for the OX Stomp is a torment: It is impossible to change the values of some of the sliders, mic EQ and delay feedback being prime examples. And why some? It is also impossible to turn the delay and reverb on and off with the app, or to tell which things, delay, EQ bands, etc, are on or off. 
The last issue I'll mention is that while using VoiceOver, multiple pages appear to be on screen at once. Give it a shot: tripple click your home button to turn on Voice Over while in the edit page for OX Stomp. Drag your finger around the screen. You will hear items that are actually not still on the screen such as the list of your other UAFX pedals. It's even possible to remove a pedal from your app from within the edit screen!
I own six of these pedals. And frankly I think VoiceOver users, those who are blind or low vision, deserve a better experience for what these pedals cost.
-- VlindMan, 2024-05-25

### *---- "Can’t Use on iPhone 15 Pro"
It crashes whenever it connects. Every 👏 single 👏 time. I would love to be able to adjust my Lion 68, but I guess that’s not in the cards.
-- ezweave, 2024-04-02

### ***** "Works great here"
Using this app with the MAX Preamp & Compressor pedal.  Bluetooth connects quickly and reliably on both my iPhone and iPad.  This app works as expected with useful features.  No issue updating firmware from my MacBook Pro (took only 2 minutes - quick).  Overall, very happy with the pedal and this app.  One feature request - on the iPad version, support both portrait and landscape mode.  I gig with my iPad and it would be nice not to have to rotate from landscape mode, to use this app easily.  Beyond that - great job UA.
-- csemasters, 2024-03-18

### **--- "Super buggy"
It WORKS, but a lot of times it’ll either just not load, or the preset name editor just doesn’t save. 

Love UA but they REALLY need to work on this app.
-- Mayo Gg, 2024-03-05

### *---- "Bad app, critical to products, no effort?"
what I don’t understand is with such consistently horrible reviews, United audio doesn’t seem to be making any changes or exerting any effort to address the situation. I would caution anybody from buying these products. They’ll probably abandon the app entirely when they have their next new idea, they are likely to become very expensive boat anchors.
