We have used this for 5 years and feel it could improve, but hasn't changed. You are forced to view the app in landscape mode. Sometimes the thermostat doesn't respond to one user, but I'd more responsive to another. We feel that you should also be able to change your password within the app. It is clunky and unintuitive. This app could use an update.

Extremely unreliable. It goes through carrier's server first, instead of directly through wifi. Their server often won't properly relay commands to my thermostat. I'll turn the temperature up one degree on the app, and I'll think it went up, but then half an hour later I'll wonder why it's still cold, and the actual thermostat will still be on the previous temperature. When it does work, it works great. But it only works 90% of the time, so it's not reliable at all. Don't use Carrier thermostats

Not a terrible app, but not good either. The app is clearly not designed for Android phones. Most of the buttons go off the screen and the text overlaps at parts. There isn't any way to change the scale and zoom out. Basically I can do a few things from the app, but for anything more complex (like changing the schedules), I'll just walk over to the wall unit instead.
