Mobile app is not user friendly!

Verified Purchase:Yes
The mobile (phone) app is not very user friendly. Sure one can adjust temp but you cannot review specific times the system was on/off the previous day!
The thermostat is great, but the app is less than par compared to others.
I would recommend this to a friend!
