Ok when it works properly

They recently fixed a bug preventing history from working so that’s a positive. However scheduling is still hit or miss if it’s going to work or not. Sometimes it changes settings like it’s supposed to, but the next schedule to put it back to “normal” doesn’t work. Sometimes it doesn’t change the settings at all. Without this function working it kind of makes scheduling pointless.

Best air purifiers!!

I have a few other air purifiers, which are good, but one of the most popular other models is much louder — plus it app it’s terrible certainly comparison to this one. The pink noise thing here is real. The units are very easy to onboard and they work extremely well. The app is utterly fantastic. I don’t know why it has such a low rating. It’s very well designed easy to get around and it’s just getting better. If you’re looking for an air purifier look no further. I evaluated a dozen of the top ones and again I have several other brands but this one is by far the best!!

App update crashes on start

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.

Fix the app

Since the last iOS update the schedule and graph are broken. I love our air purifiers but the app is poorly maintained. Either Alen and/or their developer are asleep at the wheel. It’s not the first time an update has broken features.

Achilles Heel

The biggest issue holding back the Alen air cleaner is the worthless app.

Customer service doesn’t understand the app and can’t help, while the people who we are told are working on the app won’t speak to the users.

The scheduling feature some times works, but just as often doesn’t. In addition when the time changed for daylight savings time, I had to reprogram the scheduled times because the app couldn’t automatically adjust.

The readings on the app are questionable at best, and seem to change as time goes on. If you check the readings, and then check the readings for the same time and date a few days later, the numbers are often different. No one seems to be able to say which readings are the correct numbers.

The most recent OS update broke the graphing function altogether.

Everything is supposed to be fixed with the next app update, even though they didn’t appear to know some of the problems even existed.

And of course that magic update has been promised for months now, with no expected release date in sight.
