I meant ease of use. The application is simply used instead of the remote control, e.g. turning on the device, adjusting the volume, etc. There is no need for an ordinary remote control (by the way, one, not two or more...), not to mention manual "control". By the way, the Heos application is very simple and intuitive to use and works stably. The Wiima application is "perfect" for enthusiasts due to the multitude of functions, but we do not use all services...
