The purifier itself is a beautifully designed and brilliantly executed product. However the fact that I need the app to do basic functions like set a timer or turn the bright light off at night is pretty unfortunate considering how poorly Coway has executed on the app. Having to log in every time is annoying but fine if you can just set a routine and leave it but of course that’s not what happens. Automations (like turn of light at x time) work maybe a few time (if that) then stop. Now, every night, (unless I want a bright blue nightlight) I have to go to the app, log in, navigate to the device, scroll down to manage, down to lighting, switch to off. [3/4/26 update] The routines seem to be working now. Guessing Coway is slowly working through issues. Changed rating to 3/5 ### 3/5 — 자동화 기능 부실 *2026-02-01* 자동화 설정 기능이 부실해요. 그 외에도 타 사에 있는 자동 켜짐, 자동 꺼짐 기능이 자동화 설정으로만 가능하고 공기청정기의 경우 전원이 꺼졌다가 다시 켜지면 설정해둔 모드가 초기화가 되어 매번 켜질때마다 다시 눌러줘야 하네요 (전면 집중으로 켰다가 끄고 다시 켜면 전후면으로 켜진다던가) ### 3/5 — 로그인 *2026-01-27* 들어갈때마다 로그인을 해야해서 불편해요. ### 3/5 — needs improvement *2026-01-17* Initial WiFi set took forever and had to reconnect a few times before the app screen finally said it only worked on the 2.4GHz band. Also, the scheduler feature on app does not include locking of the unit’s physical buttons (it can only be locked in the present; cannot preset lock in the scheduling. I have a cat and he never fails to mess up the pre-arranged settings because he jumps on the unit during his nighttime zoomies. If the developers can include such a feature in future updates, that’d be great. ### 1/5 — Awful *2025-12-05, version 2.17.0* The company really needs to wipe the slate clean on this app. ### 2/5 — 아쉬워요 …. *2025-12-03* 아이콘 얼음 정수기와 노블2 공기청정기 20평형을 같이 사용하는데 한 어플에서 2개의 기계가 각각의 어플로 사용해는게 너무 아쉽고 불편합니다 ㅜㅜ 한개의 어플로 다 같이 사용할수 있으면 너무 편할것 같습니다 ### 1/5 — 왜 실행이안되나요 *2025-11-28* 와이파이에서도 그냥도 앱이실행이안됩니다 ### 1/5 — Prefer the old IoCare app *2025-11-16* I have two coway app connected air purifiers. All I want with the app are notifications when the air quality is bad, and collected long term data to review when I want. I see there are these new “routines” and can’t tell if they’re active or inactive. I’d like to be able to clearly inactivate them with a slider switch, or delete them all together. The Home Screen of the app shouldn’t be showing routines unless they’re active, otherwise it’s an annoyance and not a feature. ### 1/5 — Horrible app *2025-11-06, version 2.16.0* The old app sucked because it made you login every time you use it, well this new app does the same thing except has a much worse layout and extra steps to get to the same settings. I spent an extra $100 for a headache… ### 1/5 — 제발 *2025-10-27, version 2.16.0* 과도한 다단계 영업 지겹다 ### 1/5 — So many bugs…. *2025-10-23* I keep getting notifications that the air quality is low and to turn on the filter. It is on. The app also says the air filter isn’t connected to WiFi, but the filter says it is, and how did I get an air quality alert if it’s not connected to WiFi? I also don’t understand the Routines thing. How do I delete or disable a routine? They don’t seem to work anyway, so maybe it doesn’t matter. This app is basically useless and just annoying. **Developer response:** Hello, I'm sorry for the inconvenience of using the app. To use IoCare+, you will need to re-register your existing product. If you have any problems registering your product, please send us your product serial and app screen at iocarecs-g@coway.com and we will check and inform you. ### 1/5 — New Update? *2025-10-21, version 2.16.0* App is stuck saying I need to download the new update. I already did that. I also deleted and redownloaded the app. Still says I need the new update.??? ### 3/5 — Login sticking *2025-10-16* New update as of 10/16 seems to finally keep you logged in. The issue of changing your fan speeds & having that action reset your lighting to the default setting is still occurring however. ### 1/5 — Horrible Replacement app *2025-10-07, version 2.15.1* This app is horrible. It offers less functionality than the old app. I bought my Coway air purifier specifically so I can set routines and timers. As others have noted that is no longer possible. Fix the app or lose customers, starting with me. ### 1/5 — All Style, No Substance *2025-09-25, version 2.15.1* All that effort to make the app look prettier, only to take so much functionality away. Can no longer set a detailed, customized schedule as you are forced into only limited options and need to use manual controls to dial it in. Not sure why I payed for the “smart” version. ### 1/5 — Almost like it’s *trying* to anger you *2025-09-22* This app seems to do whatever it can to irritate you. You want to login? It won’t prompt you for a saved password in your keychain. Thought that your products would have migrated over from the previous app? No way. This app isn’t built to even the lowest of standards, and Wirecutter should take note of these app reviews before recommending these products. **Developer response:** Hello. I'm sorry for the inconvenience of using the app. Please let me know your login ID at iocarecs-g@coway.com and I will check the problem. ### 1/5 — Terrible *2025-09-14, version 2.15.1* The app has no information on air quality, logs you out every time, and is basically useless. ## Most critical reviews (10 lowest-rated) ### 1/5 — Features suck *2026-07-28, version 2.24.0* This app is genuinely atrocious. Imagine paying this much for an air purifier to have an app that doesn’t show real time data like what other companies do. ### 1/5 — It really is a pile *2026-05-29, version 2.23.0* Maybe hire someone to write an app. You all have no clue how to do it ### 1/5 — Can’t link my unit, going back to older app *2026-05-26* I’ve been trying for days to link my unit. Been using it for over a year without issue, decide to try upgrading to the newer app because I’ve changed the main filter but the older one wouldn’t register that it’s been changed. Cant even connect to this app. ### 1/5 — Devices will not connect to WIFI *2026-05-01, version 2.22.0* The old app worked a fine. The new app will not do over nearby network and will not connect manually to our 2.4ghz only network. We have no mesh system and the very little bit of help available online has not worked. Basically we no longer have smart devices even though we paid more for the exact feature. ### 1/5 — 블루투스 연결 누가 만들었냐? *2026-04-06* 최근 영업당해서 비데를 더블케어2로 바꿨는데 그전에 잘되던 와이파이 연결방식을 어쩌자고 블루투스 연결방식으로 바꾼건지 이해를 못하겠다. 비데에서 조금만 멀어져도 끊겨서 지동연결도 안되는걸 뭐하러 저딴식으로 해놨는지 거의 쓰레기급이네..다시 연결할려면 휴대폰들고 변기에 앉아서 어플켜고 비데에 버튼 누르고 연결하는데 일보고 거실에 나가면 다시 끊김...아무짝에도 쓸모없는 기능..업데이트할 계획은 있는가? ### 1/5 — 어플 업데이트 후 계속 오류 뜸 *2026-04-02* 어플 업데이트 후 계속 오류 뜸 ### 1/5 — 로그인자체가 오류뜨는데 *2026-04-02* 로그인자체그 오류뜨는데 어쩌라는거야 ㅡㅡ 코웨이가 어떻게 이렇게 만들어놔 쓰라는거야 말라는거야 되지도 않는거 왜 설치하라해 어이없네 진짜 ### 1/5 — 취침설정 횟수 변경 *2026-02-24* 취침시간 설정을 1번 -> 하루에 2타임으로 할수있게 변경해 주세요. 낮시간에 다 출근하면 집에 아무도 없는데 얼음 만들고 있고 그렇다고 매번 끌수도 없고! 2타임 설정할수 있도록 변경해 주세요!! ### 1/5 — 제품 삭제 어떻게 하나요 기기 바꿨는데 *2026-01-29* 기기 바꿨는데 기기삭제도 안되고 , 비데는 앉아서 블루투스 해야지만 계속활성화 되고 어떻게 하라는거에요? ### 1/5 — Serious issues for a premium product *2026-01-04* I really want to love Coway. The purifier itself is a beautifully designed and brilliantly executed product. However the fact that I need the app to do basic functions like set a timer or turn the bright light off at night is pretty unfortunate considering how poorly Coway has executed on the app. Having to log in every time is annoying but fine if you can just set a routine and leave it but of course that’s not what happens. Automations (like turn of light at x time) work maybe a few time (if that) then stop. Now, every night, (unless I want a bright blue nightlight) I have to go to the app, log in, navigate to the device, scroll down to manage, down to lighting, switch to off. ## Most praised reviews (10 highest-rated) ### 5/5 — Bad software *2025-12-19* The best part is you can turn the lights off on your unit if you have it in a bedroom and are light sensitive. But there are a lot of bad parts. 1. The “remember me” button for staying logged in has a Terrible design that makes it look checked when it isn’t 2. If you switch the fan speed mode it forgets the setting you chose for the lights. So if you change speeds you have to turn the lights off afterwards. Every time. 3. No graphs of air quality. 4. Overly complex design for people who just own one coway device and want to use their phone as a remote for it. ### 5/5 — 앱도 안정적이고 만족합니다 *2025-07-07* 전체적으로 만족합니다. 앱도 빠르고 안정적이에요. 앞으로도 더 많은 기능과 개선이 되길 기대하겠습니다!! ### 5/5 — 사용하기 편리하내요 *2025-07-07* 화면도 직관적이고 기능도 다양해서 이전 앱보다 많이 개선된것 같아요~! ### 5/5 — 너무 편리하네요 *2025-07-03* 장소 설정 기능이 추가되서 너무 좋아요!! 앞으로 자주 사용할듯! ### 5/5 — Fantastic Upgrade! *2025-05-13* I am always a huge fan of Coway Airmega and have 250S and 400S at my home. With upgraded IoCare+ app, I can see the big improvement on connectivity with automatic pairing. Hope they do the regular maintenance! ### 5/5 — 엡이 깔끔하고 사용성이 좋네여 *2025-03-20* 엡 반응속도나 구성등 사용성이좋고 노력이 느껴지네요 앞으로도 좋은 서비스 기대하겠습니다 ### 5/5 — 좀 좋아졌네요. *2024-11-21* 이번꺼는 괜찮네. 기존앱은 너무 구려. 기존 제품은 언제 연결되나요. **Developer response:** 안녕하세요. 고객님. 기존 제품은 25년중 순차적으로 이관 예정입니다. IoCare를 이용해 주셔서 감사합니다. ### 5/5 — 너무 좋아여 *2024-11-19* 기존 IoCare앱 쓰다가 플러스가 새로 나와서 사용중인데 전보다 훨씬 편한 것 같아요 너모 편해용 따봉 ### 5/5 — 사용성 뿐 아니라 제품 사용 정보를 잘 알려주네요. *2024-11-19* 코웨이 제품 구매하고 앱에서 간단하게 제품 등록할 수 있어서 편리하게 사용하고 있습니다. 제품 제어를 할뿐 아니라, 제품 사용에 따라 리포트를 분석해주니 더 유용하게 제품을 이용할 수 있네요. ### 4/5 — 매트리스 느려서.. *2024-11-22* 매트리스 구매하고 처음 연결 했는데 제어 하러 들어가면 시간이 오래 걸립니다 앱은 깔끔하내요 속도문제좀해결해줘요 **Developer response:** 안녕하세요. 고객님. 말씀해주신 부분은 개선할 수 있도록 내부검토 하겠습니다. IoCare를 이용해 주셔서 감사합니다. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
