I quickly found out why this app has one star. It constantly disconnects, doesn’t remember my registration or login and I have sign up again only to be told I already have an existing account. I tried my Apple ID, Google, and email address and it’s hit or miss everytime. At this point I may have multiple accounts with Coway. Very frustrating just trying to login. Then after you can get on, it doesn’t really have much utility if you own multiple units, some of which doesn’t have the wifi component. As someone who has an air filter in every room, but only 2 with wifi, it’s useless to know what’s happening in 2 rooms and not the others. Way too expensive to get everything with wifi. It should be worth noting that this app is no reflection of their actually air filter products. Their air filters are the only ones I own and some of the best out there. But their app has got to be one of the worse I ever used.
