NAD OSD is a free utility and tool application available for iPhone, iPad, and Mac. Developed by Markus Mehlau, it allows users to view comprehensive status information from their NAD audio/video receiver directly on their iOS device or Mac.

With NAD OSD, users can access important and hidden settings of their NAD receiver and control them remotely, all with visual feedback. This convenient feature eliminates the need to manually navigate through the receiver's on-screen menus.

The app supports various NAD receiver models, including T 758 V3, T 777 V3, M17 V2, T 778, M15 HD (requires AM 17 and VM 300 upgrade), T 187 (requires AM 17 and VM 300 upgrade), and T 787 (requires AM 230 and VM 300 upgrade).

NAD OSD provides users with a seamless and user-friendly experience, allowing them to easily manage and control their NAD audio/video receivers from the convenience of their iPhone, iPad, or Mac.
