Does not even recognize my devices

I have two units and neither one can connect to the app. Customer service can’t help either - none of the troubleshooting steps worked. It’s hard to justify keeping these expensive purifiers where a basic functionality like this is not working.

Great Air Purifier, Terrible App

The Alen app doesn’t work. I downloaded the app 3 days ago and it constantly drops and disconnects from my iPhone and iPad. I can’t even get it to pair anymore. Not a deal breaker though. I love the machine.

Finally got app to work!

After a few tries to connect to WiFi, I was able to pair my unit. The only negative is the app will show a different color of the sensor than the unit.

Constant logouts and dropped devices make this frustrating

I keep getting logged out randomly, which forces me to sign back in every few days just to control my purifier. On top of that, my devices constantly disconnect from the app — the purifier just drops off and I have to re-add it over and over. When I finally do stay logged in, scheduling is a nightmare. The interface for turning the purifier on or off at specific times is confusing and cumbersome. It should be straightforward, but instead it feels like I need a manual to figure out how to set a simple timer. Fix the stability issues and redesign the scheduling UI — this app shouldn’t be this difficult to use.

App update crashes on start

Edit: Just tried the latest update. Still crashes on open.

I was prompted to update the app this morning. I checked out the dev notes and clicked update. I no longer have a working app. It vanishes on start up. No error. No warning. I see the app start. The logo appears. And woosh! It's gone. No more convenience for me. No more managing my device from mobile. Another unnecessary digital disappointment disguised as an update.
