App of Quality


Do what it is supposed to do and does it very well. I like the follow me and show the closest stations.

Crashes every time I connect


The app was working, now it crashes every time I open it up with my phone over wifi and try to access the connected unit to check its status and why the purifier isn’t running anymore and the purifier hasn’t run in days. What a waste of $350 and to just have a unit that doesn’t work properly and to hand over your personal info because they require you to sign up via social media and agree to their terms and conditions.

Does exactly what it should


Does exactly what it should. Displays historical data in a clear and convenient way. Appreciate being able to access locations all around the world.
