Basic control

I agree with those who say this app offers only basic controls of the thermostat. I’m glad to have that well enough — it is indeed nice to control the temp from anywhere and even turn on the energy saver. But we should be able to update the programming, too, and even set the desired humidity. The desktop app also is shockingly as basic. Why can’t the app be the same as that on the in-home thermostat itself? I see other reviews go back years here; is there never an update coming?

Good but could be better

The features programmed into the app work well. I am giving 3 stars because the functionality is basic - mainly adjusting the temperature or enabling/disabling the "away" mode. I believe improvements should be made for additional stars. For example, users should be able to view and edit schedules, view energy consumption, and manage additional settings like the background picture and brightness. Additionally, I believe Armstrong should consider partnering to integrate with Apple HomeKit.

It’s Never Updated

I have had this app for three years and do not recall that it has ever been updated. I agree with others who say it is severely limited in what it can do still It just keeps getting further and further behind other thermostat manufacturers.
