Revised from 1 to 4 stars
My original review was 1 star. The app would not connect and would not even load the tutorials. After some experimentation, I got the app to work. If you are having trouble connecting to the fan, try the following. Create an account. Log in. Turn off cell data, Turn on wifi and connect to the fan. Configure the fan. Turn cell data back on. That did the trick for me. The app has some issues but works pretty well once you get used to it.
