Bad app, good purifier
The best way to describe the app for the Airversa AP2 is minimally functional. Pros: It lets you set a schedule and look at trends. Cons: All of the “current” values it displays are usually wrong, even the settings. Examples, - The PM2.5 value, arguably the most important data the app could report, is stuck at whatever value the purifier reported when the app first launches. - When the schedule kicks in with custom settings, those are not reflected in the app at all. You could schedule Sleep mode or the fan at max and the app would never show those settings changes. 2 stars because the app has potential, but the glaring issues need to be fixed. The hardware is great, but the software really drags it down.
