I have had Honeywell Thermostats before that I liked better. The mobile app is horrible and needs alot of work. The old app worked much better with no glitches.
Seems MUCH easier to use than other manufacturers. LOVE that it is on my phone, can control from anywhere. Houghton Lake Michigan company, All Shores, did an excellent job installing. Very happy. We have two, one in main area and another in basement. We leave for the south and only heat the basement, knowing that will heat the pipes, and a 'little' on the main floor. Can now easily monitor the temp from anywhere we go.
