Constantly drops my appliances and forgets registration information

I am going crazy with this app. It keeps dropping my appliances and requesting me to re-enter registration information over and over and the support just tells me to turn off the breaker pannel and turn back on which supposedly will push some firmware and keeps repeating the cycle again. I have 4 appliances, Subzero tower refrigerator and freezer, beverage center and Wolf dual fuel range; which are not cheap and gives me this kind of performance. I was expecting a lot more.

What a complete mess and joke of an App

One star is too high a rating for this POS app. Wolf is a joke. It took 2-3 times to register the appliances - and they lost all the warranty information I entered each time. Cloud latency makes the app completely unuseable in real time. The interface looks like somebody in grade 9 developed it. Hit and miss whether there’s an info on what you’re actually changing in the settings – totally sloppy work. Two days in and dishwasher and oven just disconnect. Can’t reconnect and I don’t want to even bother. You don’t really see anything in app you don’t see or can change on the display of the appliance itself. And no , it’s not my network - i’m latest ASUS high-end meshed 3 routers on 2 Gbs pipe.

From initial sale to pre-inspection, installation registration, iPhone app, makes the wolf experience a clown show. AI Gemini or ChatGPT agree with me. Not ready for prime time – wolf is in the minor leagues. Can’t say I’m surprised after the factory certified professional installation where they left all appliances full of fingerprints smudges after install and all the packaging garbage for me to cleanup

Every new car I’ve ever bought., the dealer washed it before I got the keys. Wolf at twice the price of my last new car leaves it to me to clean and polish.

Highly overrated..Wolf is now the word for the exact opposite of white glove service. Example use: “they really wolf-ed that one didn’t they?”

Worst purchase I’ve ever made.

Recent update broke the app

Please fix this issue. I am no longer able to login.

Basic. Useless. Avoid Subzero

I’ve had subzero appliances over 30 years. Just installed high end new kitchen with the classic fridges, wine columns, glass induction cooktops, the whole nines. The kitchen/house was featured on a TV show in Magnolia Network, Dwell magazine and won a National Architectural Design Award 2025.

But we hate it because the wine column has a screen with the temperature for each section and the screen CANNOT be dimmed. The whole kitchen looks ghetto because of the wine fridge screen being super bright - like a Samsung or lg fridge.

And the app cannot manipulate the appliance. It would be the simplest thing to dim the screen until the door is opened or something like that. But Subzwro appliances are going backwards/downstream. And the appliance is a dumb privacy grab to get your information but doesn’t actually provide any benefits.

Wish I had moved away from this brand. Never again.

Buggy and intermittently works

Lacks troubleshooting. Also prompts me to register or enter serial number after it’s already been done. Edited and gave more stars—I had to reboot the fridge at the circuit breaker (not ideal) but now it works. I would like the fridge itself to include more troubleshooting options including a hard reboot from the menu. The app itself is fine but in this pricey ecosystem I think it’s fair to offer a full system review for this app as only potential big spenders will be looking at this app and it’s important to give them a review of how this smart fridge operates. The devs were super responsive at my initial one star review and this is great.

Temperature Alertd

Unfortunately, the app doesn’t provide temperature alerts resulting from a component failure. This is a must and without it the app is useless.

Horrible Experience

We installed the app, connected to the refrigerator through bluebooth. The firmware update failed! Afterwards, it denied to connect. The service center is useless. They told us they could not solve any technical problems. The so called local office is not open over the weekend. By the way, the brand new refrigerator failed the 2nd day after it was installed. The same response was given. No service is available over the weekend.

Connection Error

The basic requirement for the App is to connect to the appliance.
It stays connected for a few days and then the dreaded connection error shows up.
I’ve never experienced this with other brand IoTs.

For a luxury appliance like Sub-zero/Wolf/Cove, this App is a big embarrassment.

I have the double oven, Sub-zero and Cove and all three are showing connection errors.

Why is this so very difficult?? I have stopped using the app now.

No HomeKit integration

It’s 2026 and this app still doesn’t have HomeKit integration. It works with Alexa and Google but why not Apple?

Works when it finally connects

I had to have Wolf help me connect my appliances when I first set up the app. It worked for a while. And I loved having the information. It lost connection and will not reconnect, so I guess I will call customer service again.

Wi-Fi will not connect in three of my Ford devices

I have a brand new 3050 refrigerator 1850 wine cooler 2450 freezer and Wolf oven. Only the freezer can connect to the Internet. The others don’t find the Internet, even though it’s extremely strong signal. The app does not allow you to delete a network you’ve entered.

Bad update

Latest update breaks everything. Cant connect at all. Hangs on Bluetooth. Then hangs on wifi. Horrible.

Fix the app!

Everyone complaining that the last update caused appliances to lose connection and can’t reconnect and your only answer is to tell everyone to call customer service??? High end equipment, ridiculously low end app!!

Keeps breaking with connection error

I initially thought I had a problem with my brand new subzero but after adding the new wolf dual range, both frequently break with connection errors. I have to delete the Bluetooth connections and redo the setup. Absolutely annoying.

The only thing that is required is to be able to connect to the appliances when you open the app. How difficult could that be? I believe there are serious quality issues before releasing the app to production. I have now stopped using this app altogether.

Updates break app-appliance connection

The app is great when it works. However, every so often a bad app or server update is pushed that breaks the app’s ability to communicate with my SZ fridge. I have an older Integrated/Designer fridge that does not have an internal control panel (only physical options for power/ice maker/alarm). Everything else from fridge/freezer temperature controls, ice maker settings, and filter status are only visible and accessible via the app. So when the app breaks, the functionality of my fridge is particularly limited. I wish Sub Zero had better QA or testing prior to releasing their app updates. The bug is usually fixed within a week or so, but it is nonetheless frustrating to lose control of your expensive appliances even if it’s only temporary.

Works great when it works

After recent update my appliances can no longer connect and keeps telling me to pair my device to the appliances but it will not pair with Bluetooth

Update broke connection

I just updated to 4.5.2. My iPhone account t was logged out and my connection to the subzero refrigerator was broken. App will no longer connect to fridge. I logged out- I logged in. No connection. I deleted app and tried to reconnect- no connection. Really surprising how finnicky/useless this app is.

Daylight savings and other opportunities

I woke up today to the clock of the oven not updated. I assumed the app would do it, as there is a setting for the time zone (PST in my case) that it is still as PST.
I also assume the firmware may be outdated, but there is no indication that it is, or how to check for it.
For an item that consider “luxury” it is really under performing, as the oven should have auto updated over WiFi or the app should have signaled to do it, and indicate that the oven firmware is updated. More basic devices, like my cat feeder, have that functionality.

App is unstable

When this app is working, it is very helpful. Unfortunately, it drops appliances randomly, and then you have to put the appliance back in again and again and again. It also randomly requires your id and password, which is very annoying.
