Duet for Mac

Product overview

Duet Display, created by Duet, Inc., is a productivity app that turns phones and tablets into additional, touch-enabled monitors for macOS and Windows computers. It extends your desktop to a connected mobile device so you can move windows, use touch gestures, and expand workspace without noticeable lag or visual artifacts.

How the connection works

The app links a computer and a mobile device via a wired charging cable (Lightning or 30‑pin), then discovers and configures the external screen automatically. Once paired, the mobile device behaves as a second display and accepts touch input for navigation, zooming, and fast scrolling. The software is engineered to keep latency and pixelation to a minimum so interactions feel responsive.

Touch, gestures and drawing support

Beyond basic touch controls, connected devices can provide features useful to creative workflows. You can add a virtual touch bar to your mobile screen, perform multi-touch gestures for navigation, and use the device as a drawing surface. For artists, the app supports advanced tablet-like capabilities such as pressure sensitivity, tilt recognition, hover detection, and palm rejection—effectively turning a tablet into a graphics tablet for illustration apps.

Supported platforms

• macOS laptops running 10.9 (Mavericks) or later
• iPhones and iPads with iOS 7.0 and newer
• Windows PCs with Windows 7 or later

Reliability and performance

The application is designed to address common cross-platform connection issues and maintain a smooth experience during everyday multitasking. It focuses on stable video output and touch responsiveness so users can rely on their mobile device as an extension of their main workstation.

Upgrades and productivity benefits

An optional Duet Pro subscription unlocks additional professional features for creators. In general, using a synchronized display setup lets you keep tool palettes, reference material, or system status on the secondary screen while preserving the primary workspace—helping to streamline multitasking and boost overall efficiency.
