Dirigo is a fast, focused iPhone remote for current Marantz and Denon AV receivers. It discovers your receiver over Wi-Fi and gives you a real control surface that goes well beyond what the bundled remote can do. WHAT YOU CAN DO • Power your receiver on and off • Adjust master volume • Switch between every input source • Pick from every surround mode your receiver supports • Browse and play HEOS streaming sources — Qobuz, TIDAL, Amazon Music, TuneIn, and the rest • Manage the playback queue, see what is playing, skip tracks, view history • Switch between zones on multi-zone receivers • Configure room correction, speaker levels, HDMI output, video settings, and the deep menus your physical remote pretends don't exist • Activate Quick Selects you have programmed on the receiver • Use Home Screen and Lock Screen widgets for at-a-glance status • Trigger common actions with Siri Shortcuts ("Mute the receiver", "Turn on the receiver") TELEVISION REMOTES Pair the television or streaming box in the same room and Dirigo becomes its remote too. Apple TV gets a touchpad — swipe to navigate, tap to select — along with transport buttons and the Apple TV's own Control Centre and app switcher. Android TV, Google TV and NVIDIA Shield get a D-pad, Back and Home, and play, pause and skip. Dirigo tells you which app is on screen, recognising the common ones by name. Either way, volume routes back to your receiver instead of the television, and a live now-playing card on your home screen shows what is actually on — title, artist, artwork, and how far through it is. Drag that progress bar to jump straight to a moment. Pairing is a one-time setup: Dirigo finds the television on your network, you type in the code it puts on screen, and that is that. Only televisions appear in the list — not every other device on your Wi-Fi. DEMO MODE No receiver to test against? Tap "Enable Demo Mode" on the Welcome screen to explore every part of the app with a synthetic receiver, Apple TV and Android TV, complete with something playing. PRIVACY Dirigo collects nothing. No analytics, no identifiers, no third-party tracking SDKs, no accounts to sign in to. All receiver and television control happens entirely on your local Wi-Fi network. The only public-internet activity is when you browse a HEOS streaming source — iOS loads album art directly from the music service's own image URLs, anonymously. Full policy at bit0100bitsoftware.com/dirigo-privacy. REQUIREMENTS A current-generation Marantz or Denon AV receiver with HEOS (Cinema 50, SR-series, AVR-X-series, and similar models). iOS 18 or later. Your receiver must be on the same Wi-Fi network as your iPhone. Apple TV pairing requires tvOS 18 or later. Android TV pairing works with Android TV and Google TV devices that support the built-in remote pairing service, including NVIDIA Shield. Dirigo is an independent third-party app and is not affiliated with, endorsed by, or sponsored by Sound United, Denon, Marantz, Apple, Google, or NVIDIA.
