Why? *2026-01-28, version 1.0.7* I have never been asked for the LAN network password when installing a bluetooth product. it is bluetooth so it is direct from one machine to another. To me this is an invitation to get hacked. ### 2/5 — Primitive scheduling *2026-01-06, version 1.0.7* For an air purifier, all you can schedule is turning it on and off. How hard would it be to implement also being able to specify the mode?? Just one more digit added to the web stored schedule would allow this to be done. This means you can’t do something as simple as automatically scheduling quiet sleep mode every night and returning to auto mode during the day. It just stays in whatever mode was last used. It seems like such a simple thing to add. Over half the bad reviews are about this kind of limited app functionality. ### 2/5 — Summary of Features *2025-10-24, version 1.0.7* Here’s what you CAN do with the space heater: 1) Change Temp (has to be on eco mode) 2) Turn it on and off 3) Change Speed 4) Set a Timer That’s about it… Not much different than a non-‘smart’ heater with the same features Devs! You need to add automation and functions ### 3/5 — Scheduler is very basic *2025-07-01, version 1.0.7* The app allows control of the purifier. The schedule feature is lacking. It does not allow the selection of mode (auto) or fan speed. It only allows the unit to be powered on in the lowest fan setting ### 1/5 — Always disconnects *2025-05-07, version 1.0.7* First one never worked and the second one always disconnects ### 1/5 — App is complete garbage *2025-03-03, version 1.0.7* Constantly disconnecting everytime I add my device to the app. Have to unplug device and plug back in. ### 1/5 — STUPID. SUPER BUGGY APP *2025-02-27, version 1.0.7* Don’t waste your time ### 1/5 — Don’t recommend *2025-02-25, version 1.0.7* Boooo! Won’t even connect to air purifier! ### 3/5 — Thermostat Doesn’t Work Properly *2025-02-18, version 1.0.7* The thermostat doesn’t read correct temperature unless the unit is turned to cold setting then wait for it to start recording correct temperature. ### 1/5 — Temp Control Doesn’t Work *2025-02-12, version 1.0.7* I’m unable to adjust the temperature—it’s stuck at 77 degrees, just like others have mentioned. Since it doesn’t come with a remote, the app should work seamlessly, but it doesn’t. Overall, this product is poorly designed and not worth keeping. I’m returning it. ### 3/5 — Some bugs with Google Home *2025-02-04, version 1.0.7* When connected to Google Home, I cannot switch the light colour. Also when I turn on the device, the light colour will always default to blue. ## Most critical reviews (10 lowest-rated) ### 1/5 — Terrible *2026-01-20, version 1.0.7* You can connect the device but you can’t manage the temp! You can set the temp in eco mode. But it won’t shut off. It’s worthless ### 1/5 — Worst app ever *2025-12-26, version 1.0.7* App is completely worthless as it won’t connect. ### 1/5 — Buggy app *2025-12-05, version 1.0.7* Only way to control temperature is in eco mode. ### 1/5 — Does not work *2025-12-01, version 1.0.7* The app only works to cut the heater on and off. It does not allow to adjust temperature or setup smart scenes. So it’s basically useless. ### 1/5 — Worst app ever *2025-11-16, version 1.0.7* The app is totally useless after weeks of trying to use it I still have no idea how to turn on the heater. It just randomly shows up and you can turn it off or on maybe. Avoid this heater at all cost. ### 1/5 — Doesn’t work *2025-10-27, version 1.0.7* Boxing it up and sending it back. Will warn people where I purchased it that it’s useless. So disappointing. ### 1/5 — It’s always something *2025-09-26, version 1.0.7* I was able to connect my air purifier to the app but a day later I am not able to connect to it. ### 1/5 — NON STOP SCREECHING *2025-08-15, version 1.0.7* oh my goodness every time I try and turn on my heater I get this long, consistent never-ending beep like an alarm or something, but I have made sure that the dead man switch is good to go. It's plugged in correctly. It's updated and still it screeches unless it's on Eco mode and the temperature turned down far enough that it automatically shuts off. It is no value to me anymore. Super annoyed because I specifically bought this off of Amazon because it had functionality with Alexa. But who cares about that when nonstop screeching is happening! ### 1/5 — Absolutely ridiculous *2025-07-29, version 1.0.7* Are you kidding me this app is useless ### 1/5 — Mandatory Login Required *2025-05-21, version 1.0.7* This now requires a mandatory login before I can access settings for my air filter. Deleted. ## Most praised reviews (10 highest-rated) ### 5/5 — Works great *2026-02-01, version 1.0.7* I’m not sure why this app isn’t rated higher. It is so functional, visually appealing and easy to use. Been using it for my space heater for about a month and have no issues. The scene automation is amazing for preheating my bathroom in the morning before I’m even awake. ### 5/5 — It works how it should *2026-01-07, version 1.0.7* I’m able to turn it on it off switch the mode set timer and see how the air is when I am not home ### 5/5 — It works *2025-11-04, version 1.0.7* Got a heater, it was easy to set up in the app. Everything has been working great so far. Only thing I noticed is things can get reset if you unplug the device, so just watch for that. ### 5/5 — Useful *2025-10-15, version 1.0.7* The App is quite useful as I can control everything from my phone if needed. ### 5/5 — Device *2025-05-07, version 1.0.7* It doesn't connect ### 5/5 — Works great! *2025-01-23, version 1.0.7* Not sure what all the bad reviews are about. I can control my heater just fine. The app is very fast and responsive. My biggest complaint is the lack of Siri Shortcuts and the UI isn’t very pretty. I’d give it 4 stars, but I’m trying to balance out these senseless reviews. ### 5/5 — Works great, recently discovered Shortcuts integration *2024-02-22, version 1.0.4* App works as intended, connect with my ear purifier easily and controls it without an issue. I recently discovered that you could do tap to run shortcuts and then integrate that with Siri, which then allows you to use shortcuts to control devices with the app, pretty cool. ### 4/5 — Crashing!! *2026-01-27, version 1.0.7* App suddenly crashing can’t control heater now. Need fix asap. ### 4/5 — Nice Unit *2025-09-05, version 1.0.7* Just received this air purifier. Already liking it! Only problem is that I cannot get the Fahrenheit indicator to hold or reflect a temperature. If this could get fixed, it would make this unit “outstanding!”. ### 4/5 — Work Well *2025-06-01, version 1.0.7* I would have given a 5 star, but there is no way to turn of the device from beeping every time it changes filtration modes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
