With Android you can adjust the font size for all apps in the settings. If you select a non-standard font size, problems occur in the ThermoSmart app: The time indication, the display where you enter exceptions to the standard week, is no longer correct. In the accompanying image, the time (top right) is 11:29. The indicator for the standard week displays 12:45.

The solution is to change the font size to “normal” in the “display” option of Android.
