Sotto is a native iOS remote for Denon and Marantz A/V receivers - calm, instant and built for the couch, not the settings tree. Its signature volume dial moves in half-steps, jumps the moment you touch it, and settles when the receiver confirms - it never flickers back to a stale value. Scenes run power, input, volume, sound mode and Zone 2 in one tap. Works with Siri, Shortcuts, widgets and Control Center. Private by design - it only talks to your receiver on your own network. Free open beta.
