The unit itself works okay, but it won’t allow me to set the unit on auto and change the temperature. When I change to auto, it sets the temp at 77 degrees, and is stuck there. The app is slow and clunky. They need to put some serious thought into the app and update it. I’ve had this unit for 2 years now and wish I had gone with a different brand. Don’t waste your money unless you are good with simply changing this manually every time you need too. ### 3/5 — Only works in landscape mode on iPad? *2026-03-19, version 1.1.2* I have no issues using this app on Android but to my surprise when installing it on my iPad, I find it only works in landscape mode. Looking at the design it was obviously made for portrait mode thus making it all the more confusing why it is stuck this way. It still works fine setting up schedules, for instance. They just need to fix its orientation, better yet give us a choice. ### 1/5 — Same problem *2026-03-07, version 1.1.2* Went away for six weeks and came back and could not sign on, tried everything. Same problems as previous review. Absolutely not happy. Three days of trying to get it back on my Apple phone with no success. ### 1/5 — Now a useless app *2026-02-26, version 1.1.2* App got updated and now anything I request from the app for my units will just revert back to what it was before. It’s been fine for 9 months and just started recently ### 1/5 — Was a good app *2026-02-19, version 1.1.2* Around the end of January I lost the ability to use this app with my unit. Tried to uninstall and reinstall to no avail. Hopefully this gets fixed soon ### 1/5 — Terrible app *2026-02-13, version 1.1.2* This app never works! ### 1/5 — Horrible *2026-01-29* This app is nothing short of awful. It continuously logs you out to where you have to reconnect to the device all over again - which takes forever. The interface can be confusing and difficult to navigate as well. Very frustrating when you pay a large sum for a product and supposedly get phone features but the features are extremely faulty. ### 1/5 — APP UPDATE LOST ALL MY DATA *2026-01-24* This app (Della+) was genuinely great before the recent update. It let me control my Della mini-split AC units smoothly from anywhere no issues for months. Then the update hit, and it wiped out all my saved devices, settings, and configurations. I had to completely re-pair and re-set up every single AC unit from scratch, which was a huge hassle (multiple WiFi resets, waiting for connections, etc.). Worse, it feels like the app lost all my previous data without any warning or backup option. I’ve tried troubleshooting, clearing cache, reinstalling - nothing restores what was there. If an update is going to force everyone to start over like this, at minimum there should be a clear heads-up or data migration tool. Unfortunately, this has ruined what was otherwise a solid experience. I’m deleting the app and switching to manual controls or another solution until they fix this properly. Really disappointed, Della - please address the data loss and reconnection issues in the next update. Thanks for what used to be a working app. ### 1/5 — 2 years, 2 different networks, no connection *2025-12-27* It just doesn’t work. Everything seems to be on WiFi, from my garages to my water heater. Not these though. I scan the barcode, it just takes me back to the page to download the app. Which I have so I just open it. Tried everything. Remotes are just fine though. I would only use the app. If say I left town for a week and I forgot to turn these down. ### 1/5 — App doesn’t work on iPhone 17 *2025-12-12, version 1.1.2* You cannot change many of the functions on the unit you press +\- it doesn’t adjust the temperature you can’t change heating or cooling modes terrible design. Being WiFi enabled was a main purchasing point for this mini split. ### 1/5 — needs an update or something *2025-10-10, version 1.1.2* idk app is basically frozen , try to change temp to 75 and it goes back to 72 after 5 seconds , turned off unit with remote and went back onto app and it shows unit is still on at 72. app is easier to control unit than remote bc now i can’t figure out why it’s not giving me heat on auto mode which it was doing perfectly fine before , please fix its cold. ### 2/5 — Feels Unfinished *2025-08-27* This app works but falls short of making my units “smart”. For one the user interface between my ceiling cassette and high wall unit is totally different. I understand functionality is somewhat different but feels like two separate apps. My biggest frustration is that I can’t set the ceiling cassette fan mode to auto in the schedule. Such a simple feature that isn’t there. This could be refined and could have functionality like my old Nest thermostat but instead they market this app as if it’s feature rich and instead it falls very short of a full functioning app. Will probably buy 3rd thermostats like Cielo Breez Max. ### 2/5 — Clunky *2025-08-12, version 1.1.2* The app works…when it works. Not user friendly to add units. If something goes wrong (for example, wifi goes offline), it won’t seamlessly reconnect like ALL MY OTHER APPS WITH EVERYTHING ELSE I OWN. With this app, I have to go back in and make them start talking again. Again - clunky app and not user friendly ### 2/5 — Can’t use the schedule feature anymore *2025-08-07* I had a schedule that worked but I needed to change it. So I deleted the current schedule and started to create a new one. Once you’ve set all the parameters and click confirm, the button doesn’t do anything and the schedule will not save. Please fix this ### 1/5 — Bad app *2025-06-28, version 1.1.2* 2.4ghz doesn’t come up for pairing. Tried 2 phones. What is this, a 2010 model? ### 2/5 — 🙄 off the 🏏 *2025-06-27, version 1.1.2* Just the thought that--before even being able to PAIR my new, $450 portable AC to the app--I NEED TO CHANGE my 2.4GHz Wi-Fi Channel NAME, in order for this APP to RECOGNIZE it as a 2.4GHz bandwidth router, is pro'lly the most half-baked, ridiculous programming I've ever seen. While the app tells you the URLs for SOME popular brands, which you need to access/change the name (specifically by adding "-2.4G" to it), it's insane that not only does the app/unit REQUIRE a 2.4GHz bandwidth connection (yes, this IS the middle of 2025, a decade past Marty McFly's trip to the future). What's worse, that also means I'll need to figure out EVERY DEVICE I HAVE on my 2.4GHz bandwidth and re-connect them using new 2.4 network name. PERHAPS WORSE is that I need to CONNECT my PHONE to the SAME, slow-connection network as the app/device, in order to have the phone/app on the same network as the device, itself. That this REQUIRES a 2.4GHz connection is ridiculous, from the start, because the mid-Aughts (when 2.4 GHz Wi-Fi bandwidth was king) were 20 years ago, but that it can't recognize a 2.4 GHz network bandwidth makes it like a baby's toy... 🤦‍♂️ (This app had better make me lunch, too, at this point... ) ### 1/5 — Bad updates *2025-06-21, version 1.1.2* It was wonderful. Now I can’t figure out how to get the air conditioner back onto the app. ### 1/5 — Too much *2025-06-14, version 1.1.2* This app requests wayyy too much to connect the mini split and then doesn’t work for me. Waste ## Most critical reviews (10 lowest-rated) ### 1/5 — Stupid engineering *2026-08-02, version 1.1.3* You can tell this company pays their engineers very little and engineers their products stupidly. Every once in a while they will update their app, and surprise! All your devices are unpaired, you have to factory reset them all to get them to connect to WiFi again. All of your schedules are deleted, and you have to spend half an hour setting it all up again. So smart, Della. ### 1/5 — Excelent unit, terrible app *2026-08-01, version 1.1.3* Excellent 220 volt cooling unit. The mobile app is terrible; can only adjust temperature to lower, not higher. You have to change mode and circulate back to cool to make plus work. Also, stuck on celsius, cannot change to Fahrenheit ### 1/5 — Bad *2026-07-26, version 1.1.2* Gets out of sync with remote . ### 1/5 — Sorry app *2026-07-05, version 1.1.2* It takes forever to download the app got a code for error 8 can’t find the code inside the ln book that came with the ac ### 1/5 — What happened?! *2026-07-01, version 1.1.2* Used to work perfect now barely works ### 1/5 — Horrrible App *2026-06-30, version 1.1.2* Cant log into the app. Plain lame & sorry app. ### 1/5 — Stop changing stuff!!! *2026-05-11, version 1.1.2* Stop changing stuff that works! I can’t even get to my schedule anymore!!!! Now I’m stuck on heat when it should be on dehumidifier!! ### 1/5 — App Is Terrible *2026-04-24, version 1.1.2* Before the update. It use to let me control temp and allow me to turn it on from anywhere i was at the time. Now i have to be within 5 ft to even turn it on from my phone. It wont allow me to set a schedule! Please Fix! ### 1/5 — App Stopped Working *2026-04-23, version 1.1.2* The app worked great for a year, now it’s not connecting to the unit. ### 1/5 — App is unusable *2026-04-19, version 1.1.2* At this point the app is unusable at best. Most of the time less than half buttons work. Also Alexa integration is just as bad. Alexa shows temp is set to 144 but the app shows 62. Actually unit is set to 67. Thank god the remote and unit functions correctly. ## Most praised reviews (10 highest-rated) ### 5/5 — Della mini split *2022-10-24, version 1.0* Is very good mini split for my garage I love it ### 5/5 — Pretty good but *2021-12-26* The app is pretty good. Would be better if it reported actual temp indoors and outdoors as well as the current set point for temp management. Some other makers have that bit and it is a real help ! Possible update? ### 5/5 — Easy to use *2021-12-08, version 1.0* Integrated seamlessly with my AC. Would recommend to everyone I know. Della makes great items at affordable prices. ### 5/5 — The future is now *2021-11-19* Recently purchase a Della dehumidifier which can be controlled through the app. The app is fairly easy to use and controls all the functions on the dehumidifier. It also seems it can connect to other Della products which is convenient. ### 5/5 — Works well with Della product. *2021-11-19, version 1.0* I have a della portable AC/Heater and this app works very well. You can control your product through this app simple and easy. Well made! ### 4/5 — Small Issue with Siri Shortcuts *2025-08-01* Im enjoying my unit so far, connectivity is great and im able to control all listed features from my phone. My only issue is im looking to integrate the appliance further into my smart home, and have used the provided "add to siri" option within the app. However nothing works when i try to use any of the shortcuts, the unit beeps so it is receiving the commands, but then never actually turns on. would love any kind of assistance on troubleshooting this ### 4/5 — App glitching *2024-12-02* The app started off great but now it’s glitching all the time. It will go back to different settings after trying to set specific settings and it makes the unit beep 3-6 times with each change. ### 4/5 — Greatly Improved App *2024-07-13* New App is great. Only thing I can think of would be the ability to save a schedule, so you can easily get rid of it if you won’t be home for a few days then add it back when you get home, especially if it is a complicated schedule. ### 4/5 — IOS 16 - Della UI Needs Update - Stopped working for 2 devices *2022-09-24, version 1.0* Hi! Everything’l was great, I have two DELLA dehumidifiers and I can control them both. However, with the iPhone 14Pro / IOS 16, the “back” button no longer works to go back and change to the other devices (upstairs vs downstairs). You are “stuck” because the “back button” doesn’t work, so you need to kill the app , relaunch and select the other device. Needs recompile for new phone; developers please help. :-). Thanks and, zero issues otherwise. ### 3/5 — What Privacy Policy? *2026-07-21* I downloaded the app and in the Privacy agreement I began reading some of the data collection info. I clicked on the Privacy Policy for more information and the page had NO information. Whether it was a glitch, oversight or otherwise, I’m not really interested in an app if they can’t figure these things out first…I’ll just use the remote. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
