This app allows remote control of a Network Player or a Network A/V Receiver via the local network.
The app supports Onkyo/Pioneer/Integra released in April 2016 or later and Denon/Marantz with build-in HEOS technology.
Some TEAC models like Teac NT-503 are also supported.

The two most popular features of the app are music playback and sound profile management.

This "Premium" version implements exactly the same receiver control functionality as the free version, but has more flexible user interface.
It allows to create home screen widgets for playback control and shortcuts, reorder the play queue using drag-and-drop, change the font and buttons size and show/hide/reorder all control elements for all tabs.

Other benefits include:
