Features
Read full description

Turn your iPhone or iPad into a custom control deck for your Windows PC or Mac. Put app-volume faders, OBS controls and macros together in Custom Modes. BUILD YOUR DECK Arrange and resize blocks, use a template or start with your own layout. Free includes one mode with up to six blocks, two assigned audio apps and six saved macros. Pro supports up to 20 modes with 40 blocks per mode. Saved Pro macros are uncapped; each macro button still uses a block. CAMERA & MIC FOR OBS With Pro, send your iPhone camera and microphone to OBS over local Wi-Fi. Use supported lenses, zoom, background effects and face-tracked AR props. Effects and lenses depend on your device. AUDIO AND OBS CONTROL Balance app volume from your deck and add OBS input faders or mute controls. Pro adds dedicated broadcast action blocks, scene switching, live previews and hold-to-talk or hold-to-mute controls. Supported OBS hotkeys and the current-scene block are available on Free. MACROS AND WIDGETS Run saved desktop macros from your deck, Home Screen or Lock Screen widgets. Your paired desktop must be reachable.
