Pearl Thermostat - how to see on/off

Just installed a Pearl Thermostat and it connected okay.
I can set the temp through Classic App without a problem. My system is only heat (no fan, no AC).
On the app, should it show when the heater is on or off? I can see what the set temp is and what the current temperature is, but is there any colour or flag or something to show the heater is on or off?
