And I loved having the information. It lost connection and will not reconnect, so I guess I will call customer service again. ### 2/5 — Updates break app-appliance connection *2026-03-17* 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. **Developer response:** griffinhunt - Thank you for reaching out and sharing your experience with us.

Thank you, Digital Product Experience Team ### 3/5 — Works great when it works *2026-03-16, version 4.5.2* 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 ### 3/5 — Daylight savings and other opportunities *2026-03-09* 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 I also assume the firmware may be outdated, but there is no indication that it is, or how to check for it.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. **Developer response:** GreatCompa - We apologize for the inconvenience. For your appliance, please follow instructions here: https://www.subzero-wolf.com/assistance/answers/multi-brand/time-sync-on-connected-products. Thank you, Digital Product Experience Team ### 3/5 — 3/7/26 - Login from app not working. But, login from web browser works. *2026-03-07, version 4.4* 3/7/26 - Login from app not working. But, login from web browser works. ### 3/5 — App is unstable *2026-02-28, version 4.4* 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. ### 2/5 — Hangs after iOS 26.x *2026-02-15* Takes a long time to launch, allow changes in set points in app but this doesn’t result in changes inside the SZ. Quickly hangs after that. All this started after the iOS 26.0 update. This has been going on a long time now without a fix even though we’re now on iOS 26.3. Yes using the latest app. Prior review: This app is simple to use and provides notifications for door open or filters needing replacement. While it does report set points, it does not give any warning when actual temperatures increase well into warm conditions. Consequently you get no indication that you have a problem until it becomes obvious when you see food thawing or open the door and check temperatures. There are virtually no diagnostic flags. **Developer response:** Good morning, bck17 - We are sorry you are experiencing an issue with the SZG Owner's App. Our developers are actively working on a solution to the issue you mentioned. We appreciate your patience. Sincerely, Digital Product Experience Team. ### 2/5 — Regressive update! *2026-01-08* Whatever you guys have done in your most recent update, you have introduced regressive bugs into your application. Whenever I open the app now it takes forever to load my appliances….” loading additional appliances.” another issue I’ve noticed is that when I change my refrigerator from short vacation to normal or normal to short or any variation there of while the change is submitted to my refrigerator the application does not reflect the change. Come on guys test your applications better. **Developer response:** Erased94 - Thank you for your candid feedback. Our team is actively working to improve the app, which will address your concerns. Please contact our Customer Care Team at (800) 222-7820, Monday-Friday 7:00 a.m. - 7:00 p.m. if you have questions or would like assistance. Kindly, Digital Product Experience Team ### 3/5 — Won’t allow me to set Night Ice *2025-12-29, version 4.4* Has this been updated for iOS 26? I can’t set my ice maker to night ice (or anything else) and the app is saying my ice maker is off when it is on. Wondering when this will be fixed. ### 2/5 — Big disappointment *2025-12-19* I expected much more from this app and this appliance at this price point. I purchased this and it was installed new 4 weeks ago. I assumed it would provide current internal temperature for both refrigerator and freezer. It did not. I lost power 5 days ago when a breaker tripped and I was out of town. No notifications. Went I got home everything inside was warm. My app only said ‘refrigerator offline’ while I was out of town. But it will notify me if someone changes the internal temperature set point. I have yet to figure out how that would be helpful. **Developer response:** Levarlaw - Thank you for reaching out. We are sorry to hear you experienced a power outage, which interrupted connection, impacting the ability to send notifications. We appreciate your suggestion to improve the user experience and will share your feedback with our developers. Best, Digital Product Experience Team ### 1/5 — Garbage app *2025-12-13, version 4.4* Get constant notifications about replacing air purifier, when you go to order the parts through the app you get endless cycles of the app crashing, asking you to sign in and error after error. They just use juveniles do app developers. What a joke. ### 2/5 — Water filter notification *2025-12-03, version 4.4* After replacing the water filter in our Sub-Zero refrigerator there is not option to reset the filter life in the water filter section of the app. I was able to reset the air purification filter’s life but tapping the “Reset cartridge life” option. But no such option is available for the water filter. It continues to show 0% for “filter life remaining”. Am I doing something wrong? ### 1/5 — It doesn’t work *2025-11-27, version 4.4* Where are the WiFi settings that let me connect to the appliance ??? All it does is let me register ### 1/5 — Garbage… *2025-11-26, version 4.4* This app only has the use and care guide.. and recipes, which doesn’t work anyways… there’s NOTHING on this app about actually controlling the oven or seeing the status of what you’re cooking…. WHATEVER.. ### 1/5 — Constant connection trouble *2025-11-22* Constant connection trouble. I have this app for several subzero devices in a vacation home. They constantly go offline and SubZero support says to go to the circuit breaker to reconnect. This is obviously disappointing, especially for use in a vacation home, as we are not usually there and expectations were to be able to remotely make sure all subzero products are running while not there, but this app has consistently failed to deliver for 2+ years now. **Developer response:** EMTapple - We are sorry you are experiencing issues with connection. If your product is offline, we recommend rebooting your Wi-Fi router. You may need to pair the appliance again. If you have questions regarding next steps, please contact our Customer Care Team at (800) 222-7820, Monday-Friday, 7:00 a.m. - 7:00 p.m. Central. Thank you, Digital Product Experience Team ### 2/5 — Problem with new update *2025-11-17, version 4.4* This new seat update caused the app to disconnect from wifi and can’t pair with range ### 1/5 — subzero fridge *2025-11-05, version 4.3.1* tried to connect multiple high end sz fridges to app. never once could connect. today you open app and ' we are experiencing technical difficulties and working to resolve issue. last updated 7/13/25' it's november 2025. epic fail ### 1/5 — Link to a non-exist page *2025-10-29, version 4.3.1* The very first page upon opening the app goes to login.subzero-Wolf.com, which doesn’t exist, so can’t move on whatsoever. ### 1/5 — Can’t log in *2025-10-29, version 4.3.1* I can’t log into my account from the app. Spent an hour on the phone with 3 different people from subzero-no luck. Deleted app 3 times, restarted phone, still nothing. ## Most critical reviews (10 lowest-rated) ### 1/5 — Connection Error *2026-05-07, version 4.5.4* 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. ### 1/5 — No HomeKit integration *2026-05-04, version 4.5.4* It’s 2026 and this app still doesn’t have HomeKit integration. It works with Alexa and Google but why not Apple? ### 1/5 — Wi-Fi will not connect in three of my Ford devices *2026-04-11, version 4.5.4* 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. ### 1/5 — Bad update *2026-04-10, version 4.5.4* Latest update breaks everything. Cant connect at all. Hangs on Bluetooth. Then hangs on wifi. Horrible. ### 1/5 — Fix the app! *2026-04-08, version 4.5.4* 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!! ### 1/5 — Keeps breaking with connection error *2026-04-01, version 4.5.4* 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. ### 1/5 — Update broke connection *2026-03-15, version 4.5.2* 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. ### 1/5 — Water filter reset *2026-01-25, version 4.4* There is now no way to reset the water filter life on my Subzero ic30ridx after this update. ### 1/5 — The worst app I’ve ever used *2025-12-25, version 4.4* Oven keeps disconnecting from WiFi and it’s nearly impossible to reconnect using this app. Total junk! Majority of our Wolf appliances have had issues and have been replaced. Don’t waste your money buying anything from Wolf. ### 1/5 — App is trash! *2025-12-14, version 4.4* We own 6 wolf /sub/cove appliances and not one of them will connect when using the app. Hoping all of them connect is a fantasy. It’s a series of can’t connect and error messages. Why is this group boasting a feature like this that is so unreliable? ## Most praised reviews (10 highest-rated) ### 5/5 — Celsius now available *2026-02-22, version 4.4* Finally, Celsius is available to be selected in the app! ### 5/5 — As outstanding as their appliances! *2025-01-29* The Sub-Zero Wolf app is exactly what a smart appliance app should be—intuitive, responsive, and actually useful. It doesn’t just look polished; it works flawlessly, making it easy to control and monitor appliances without unnecessary steps or frustrating lag. The layout is clean and useful, from changing temps and bake modes to maintenance reminders and timer alerts happening in real time without any hiccups. The app feels like an extension of the appliances, not just an afterthought, and that’s expected with Sub Zero & Wolf. There’s no alternative. **Developer response:** ThatcherLuv - Thank you for sharing your feedback, as the user experience and voice of the customer is extremely valuable. Sincerely, Digital Product Experience Team ### 5/5 — Very happy with all improvements over the last year *2024-09-09, version 4.0.1* As the title states I am very happy with all the improvements over the last year. Please keep it up. It is not taken for granted it will help you retain customers like myself. ### 5/5 — Wonky where attempting to register an appliance *2024-04-25* Wonky where attempting to register an appliance. Be prepared for ambiguous errors. You may need to call customer support to complete the process. Luckily, they are good about answering the phone and trying to help by making changes in their database. **Developer response:** Hi Jeff - We are sorry for any errors you encountered during the connection process and appreciate your feedback. As you mentioned, if you continue to experience issues, our Sub-Zero Customer Care Team is available at (800) 222-7820, Monday-Friday, 7:00 a.m. - 7:00 p.m. Central to help. Best, Digital Product Experience Team. ### 5/5 — Tad Bit Wonky *2024-02-11* I’ve recently changed my phone number since installing the app. It doesn’t allow me to change my login information for the two factor identification. It has my old phone number with no option for updating it. Called customer service but the only suggestion was to create a new account.. I expected a better resolve, especially since I no longer have the same phone number. **Developer response:** MzGlamourAddict - We apologize for the inconvenience and that we were unable to assist when you called.

Notifications are helpful and work across my wolf, cove and sub-zero units. Excellent job! I really love that I get a notificacion on my Apple Watch when the oven is preheated. **Developer response:** Thank you for your feedback, Nodine! ### 5/5 — Smart Appliances that work *2023-08-08* The app has appropriate and helpful features which make it more than just a gimmick.
