Why I can't install apps on my watch from IQ store just using Garmin express? They demand to install the android app on my phone device
Based on my research, it appears that Garmin made the decision to require the use of the IQ Store app rather than add app-installation capabilities to Garmin Express. This is not illogical if the watch has wireless connection capability to an android phone. Cardo, the headset manufacturer, has done this too. You can update the firmware using software on a PC but can only manage settings with their iPhone or Android app.
