I’m sorry but this app is trash or the machine has defects - every time I connect the machine to the app, it works for a day, then the app loses connection to the machine in another day. The setup is supposed to be a one time deal. No? This bug gotta be fixed or else the app is useless. Also, the app doesn’t have a lot of features like some other air purifiers on the market - i.e. the dyson purifier shows analytics throughout the day so you can track which time of the day has the most particulates in the air and it even shows what kind of matter it is so you can be more aware of things to look out for. On this app? No such thing. I think the hardware technology on this air purifier is impressive but the software tech is basic and boring.
